IEC 60068 2 1: Cold Temperature Testing

The IEC 60068-2-1 standard is a crucial international guideline used to evaluate the ability of components or equipment to function, be transported, or stored at low temperatures. IEC 60068-2-1 cold temperature testing is typically performed on products across various industries, including industrial, medical, and commercial sectors. At Delserro Engineering Solutions (DES), we specialize in conducting these tests to ensure products meet stringent low-temperature performance standards.

To learn more about the broader IEC 60068-2 series and its applications across different environmental testing scenarios, you can also refer to our comprehensive guide on IEC 60068-2.

Cold Temperature Testing: Categories and Procedures

IEC 60068-2-1 testing is divided into tests based on whether specimens dissipate heat. This cold temperature testing is designed to simulate low-temperature conditions gradually to determine product resilience.

Cold tests for non-heat-dissipating specimens
- With gradual temperature change, Test Ab
Cold tests for heat-dissipating specimens
- With gradual temperature change, Test Ad
- With gradual temperature change, specimen powered throughout, Test Ae

Test Ab: Cold test for non-heat-dissipating specimens with gradual temperature change
In this test, the item is placed in a chamber set at ambient temperature. The temperature is gradually lowered to the specified cold condition. Once the item stabilizes at the cold temperature, it is maintained under these conditions for the required duration to assess its performance.

Test Ad: Cold test for heat-dissipating specimens powered after initial temperature stabilization
For heat-dissipating specimens, the item is placed in a chamber at ambient temperature, and the temperature is gradually lowered to the specified level. After temperature stability is achieved, the item is powered on, allowed to stabilize again, and then exposed to cold conditions for the designated period.

Test Ae: Cold test for heat-dissipating specimens powered throughout the test
The specimen is placed in a chamber at ambient temperature and powered on from the start. A functional test is performed before the temperature is gradually lowered to the specified level. After stabilization at the cold temperature, the specimen remains powered and is continuously monitored for correct operation under test conditions for the required time.

After the specified duration, the temperature is gradually increased back to ambient levels. A post-test evaluation and visual inspection are conducted to check for any adverse effects. IEC 60068-2-1 provides recommended cold temperature severities and durations, which can be selected directly from the standard, adapted from known environmental data, or based on data sources such as IEC 60721.

In addition to IEC 60068-2-1 cold temperature testing, Delserro Engineering Solutions offers a wide range of environmental and climatic testing services to ensure that products meet rigorous standards across diverse environmental conditions.

How Do Extreme Shock Environments Impact Aerospace Components?

Have you ever wondered how aerospace components are designed to survive the extreme forces they face during space missions? Whether it’s enduring the immense pressure of a rocket launch or withstanding the violent jolt of stage separation, aerospace components are regularly subjected to some of the harshest conditions imaginable.

In the aerospace industry, failure is not an option. A single malfunction in a critical component can spell disaster for an entire mission, leading to enormous financial losses or even endangering lives. This is why aerospace engineers must take into account the extreme shock environments their components will face and ensure they are built to withstand these intense forces.

At Delserro Engineering Solutions (DES), we specialize in protecting aerospace components from the destructive impact of these shock environments. With over 30 years of experience in advanced shock and vibration testing, our team knows exactly what it takes to ensure that aerospace components thrive in the most challenging conditions.

Reach out to us today to learn more about how we can help ensure your aerospace components perform reliably, even in the most extreme shock environments.

Understanding Extreme Shock Environments in Aerospace

Extreme shock environments are one of the most challenging aspects that aerospace components must endure. These environments expose components to sudden, high-intensity forces that can cause immediate or long-term damage. Without thorough preparation and testing, critical aerospace systems may fail.

Aerospace shock events can occur during multiple phases of a mission, including:

Rocket launches: During liftoff, components face immense G-forces as the rocket accelerates. These forces can test the limits of structural integrity and function.
Stage separations: When a rocket’s stages disengage mid-flight, the explosive force of separation can create a sudden shock wave that impacts all connected components.
Ballistic impacts: Collisions in space, whether intentional or due to debris, generate shock waves that can damage mechanical and electronic parts.
Reentry forces: As spacecraft reenter the Earth’s atmosphere, rapid deceleration and high-intensity vibrations place extreme strain on their components.

Each of these events creates stress in the form of acceleration (measured in G-forces) and vibration frequencies. Although these forces last for mere milliseconds, they can lead to significant wear or immediate failure.

Why Shock Environments Matter

For aerospace engineers, these extreme shock environments present a critical challenge. Without the proper design and testing, components are vulnerable to:

Systemic failures: Sensitive electronics or mechanical parts may malfunction due to shock stress.
Structural damage: High G-forces can result in material fatigue, cracks, or deformation, threatening the overall integrity of the spacecraft.
Shortened lifespan: Continuous exposure to extreme shocks, without sufficient testing or design improvements, can reduce the functional lifespan of vital aerospace components.

MIL-STD-810 Pyroshock Testing

MIL-STD 810 Method 517 Pyroshock Testing is performed to evaluate whether products can withstand the shock effects caused by the detonation of a pyrotechnic device, typically found in missiles or rockets. A pyroshock test can also be used to determine an item’s fragility level experimentally. This allows for the application of shock mitigation techniques to protect its structural and functional integrity. The latest revision of this test standard is Method 517.3 from MIL-STD-810H.

DES is a leader in MIL-STD-810 Pyroshock testing, having performed hundreds of tests using our state-of-the-art Mechanical Impulse Pyroshock Simulator (MIPS).

Understanding Pyroshock

A pyroshock creates a stress wave that propagates through the structure into components that are mounted to the structure. A Pyroshock has the following characteristics:

Frequency range from 100 Hz up to 10,000 Hz and beyond
High accelerations from 300 G’s up to 200,000 G’s with low structural velocity and displacement response
Short-time durations less than 20 milliseconds

Common Failures caused by Pyroshock Impulses?

Destruction of the structural integrity of micro-electronic chips
Electrical relay chatter causing operational faults
Circuit board malfunction and/or damage
Electronic connector failure or momentary disconnects
Cracks and fractures in crystals, ceramics, epoxies, or glass envelopes

Pyroshock definitions are from MIL-STD-810H, Method 517.3

Near-field Pyroshock. The stress wave propagation effects govern the response. Near-field pyroshock tests require frequency control up to and above 10,000 Hz for amplitudes greater than 10,000G’s. A pyrotechnically excited simulation is mostly used, although in some cases a mechanically excited simulation technique may be used.
Mid-field Pyroshock. The pyroshock response is governed by a combination of material stress wave propagation and structural resonance response effects. Mid-field pyroshock tests require frequency control from 3,000 Hz to 10,000 Hz for amplitudes less than 10,000G’s. A mechanically excited simulation technique other than shaker shock is typically used.
Far-field Pyroshock. The pyroshock response is governed by a combination of material stress wave propagation and structural resonance response effects. Far-field pyroshock tests require frequency control no higher than 3,000 Hz for amplitudes less than 1,000G’s. An electro dynamic shaker or a mechanically excited simulation technique is typically used.

Method 517.3 Pyroshock has Five Testing Procedures:

Procedure I – Near-field with an Actual Configuration. For Procedure I, the pyroshock is replicated using the actual material and the associated pyrotechnic shock test device configuration.
Procedure II – Near-field with a Simulated Configuration. Procedure II replicates the pyroshock using the actual material, but the associated pyrotechnic shock test device is isolated from the test item. For example, by being mounted on the back of a flat steel plate.
Procedure III – Mid-field with a Mechanical Test Device. For Procedure III, replication of the pyroshock is performed using a mechanical device that simulates the pyroshock peak acceleration amplitudes and frequencies. A mechanical device such as DES’s MIPS is used. An electrodynamic shaker is not capable because of frequency range, peak acceleration and weight limitations.
Procedure IV – Far-field with a Mechanical Test Device. Procedure IV also replicates the pyroshock with a mechanical device such as DES’s MIPS. An electrodynamic shaker is not capable of performing Procedure IV pyroshocks because of limitations.
Procedure V – Far-field with an Electrodynamic Shaker. The pyroshock is replicated using an electrodynamic shaker to simulate the low frequency structural resonant response.

How MIL-STD-810 Pyroshock Testing is Performed at DES?

The pyroshock test criteria, including the required Shock Response Spectrum (SRS), are provided to DES. A specialized fixture is then fabricated to attach to our shock test equipment. The test setup is experimentally determined using a mass model to achieve the required SRS. Once the SRS is replicated with the mass model, the actual test item is tested on the shock apparatus. The shock pulse is captured using high-speed data acquisition and specialized shock accelerometers, with SRS plots calculated and analyzed using our specialized software.

The testing is performed along 3 orthogonal axes. In most cases, the required SRS is achieved in both positive and negative directions during a single strike. Upon test completion, DES promptly delivers a detailed report that includes pyroshock plots, test observations, results, and color photographs of the setup and any failures.

MIL-STD-810 Combined Environments Testing

MIL-STD-810, Method 520 Combined Environments Testing is performed to evaluate the synergistic effects of temperature, altitude, humidity, input electrical power, and vibration on airborne electronic and electro-mechanical material. Combined environments testing is critical as it may induce failures that would not be exhibited during individual environment testing.

Additionally, the combined environments can amplify stresses, making this testing more reflective of real-world conditions than testing each environment separately. It’s important to note that MIL-STD-810 Combined Environments Method 520 is not intended as a replacement for methods 500, 501, 502, 507 and/or 514 unless specifically tailored and specified in customer requirements. The latest revision of the Combined Environments Test protocol is Method 520.5 from MIL-STD-810H.

DES is the right choice because we are a MIL-STD-810 accredited lab and will help you navigate through Method 520 Combined Environments testing.

Some of the Failures caused by Combined Environments are:

Shattering of glass vials and optical material.
Binding or loosening of moving parts.
Separation of constituents.
Performance degradation in electronic components due to parameter shifts.
Electronic optical (fogging) or mechanical failures due to rapid water or frost formation.
Differential contraction or expansion of dissimilar materials.
Deformation or fracture of components.
Cracking of surface coatings.
Leakage of sealed compartments.
Failure due to inadequate heat dissipation.
If the material is powered, component over-temperature failures.
Circuit Card Assembly failures due to short circuiting.
Failure of Electromagnetic Interference (EMI) filters.
Errors due to input electrical power frequency variances.

Method 520 Combined Environments has three Procedures

Note: It is recommended that single environment tests be performed prior to these procedures to verify system performance under discrete environmental parameters.

Procedure I – Engineering Development. Procedure I is used to find design defects in new or modified equipment while it is still in the development stage. After anomalies are found, a root cause analysis is performed to determine the corrective action. Subsequent testing may be performed to aid in the root cause analysis. The subsequent tests may use higher stress levels than the product is likely to encounter on a regular basis in the field. Test durations are based on the time required to induce expected failure modes. This procedure is not a substitute for Environmental Stress Screening (ESS) or Highly Accelerated Life Testing (HALT).
Procedure II – Flight or Mission Support. This procedure is performed in preparation for a specific mission scenario. It can also be used to troubleshoot field returned materiel exhibiting specific mission problems. The damage accumulation in Procedure II should be no faster than in normal operational or flight testing. Test durations should be the same as the design mission or, if troubleshooting, sufficient to identify materiel anomalies. This procedure is not intended to be used in lieu of Procedure III.
Procedure III – Platform Envelope. The Platform Envelope test is intended to verify compliance with specific platform/equipment specifications. This testing utilizes the most significant combination of environmental stress conditions. A minimum test duration of 10 cycles is required.

Advanced Acceleration Testing Lab for MIL-STD-810 Standards

MIL-STD 810, Method 513 Acceleration Testing is performed to evaluate whether products can withstand steady state inertia loads and the effects of acceleration forces. It is also used to ensure that material does not break apart and become hazardous after exposure to crash inertia loads. The acceleration testing lab ensures that materials do not break apart and become hazardous after exposure to crash inertia loads. Inertia loading is also commonly referred to as G force. Typical applications for MIL-STD-810 Acceleration Testing are for products installed in helicopters, aircraft, aerospace vehicles, and missiles. The latest revision is Method 513.8 from MIL-STD-810H.

Some of the Failures caused by Acceleration Forces are:

Structural deflections that interfere with operation
Permanent deformation, structural cracks, and fractures
Broken fasteners and supports that result in loose parts within products
Broken mounting hardware that results in loose material within an assembly
Electronic circuit boards that short out and circuits that open up
Inductances and capacitances that change value
Relays that open or close
Actuators and other mechanisms that bind
Seals that leak
Pressure and flow regulators that change value
Pumps that cavitate
Spools in servo valves that are displaced causing erratic control system response

DES is the right choice for MIL-810 Acceleration testing. DES has extensive experience performing acceleration testing and has a state-of-the-art centrifuge capable of performing MIL-STD-810 Acceleration testing.

Comprehensive MIL-STD-810 Acceleration Testing Lab

MIL-STD-810 acceleration testing lab services are essential for products subjected to high acceleration environments. Delserro Engineering Solutions (DES) is equipped with the expertise and state-of-the-art centrifuge to perform these rigorous tests.

The product is mounted on a fixture using hardware that is normally used in its service installation. The fixture is then mounted to DES’s centrifuge. If it is an operational test, the device under test is powered and monitored through DES’s slip rings. The centrifuge is brought up to the speed required to induce the specified G level. The G force is maintained for at least one minute after the centrifuge rpm has stabilized. The testing is performed in six directions (1 positive and 1 negative direction along 3 orthogonal axes).

Upon completion of the acceleration test, DES will promptly deliver a detailed test report that includes acceleration plots, test observations & results, color pictures of the setup and color pictures of any failures.

Procedures in MIL-STD-810 Acceleration Testing:

Procedure I – Structural Test. This procedure is used to demonstrate that items will structurally withstand the inertia loads induced by in-service accelerations. The test item is non-operational.
Procedure II – Operational Test. Procedure II is meant to evaluate whether devices will operate properly while being subjected to a specified G-level.
Procedure III – Crash Hazard Acceleration Test. Procedure III is intended to verify that material will not fail and break apart during a crash, becoming hazardous to equipment or personnel. This is a critical aspect of MIL-STD-810 Acceleration Testing.
Procedure IV – Strength Test. Procedure IV is an alternative to acceleration testing. It is suitable for testing relatively stiff components, electronics boxes, instruments, or space vehicles. It is performed as a sine burst test in which the test article is subjected to a few cycles of sinusoidal input below its first resonant frequency to expose the hardware to a quasi-static loading.

MIL-STD-810 Salt Fog Testing

MIL-STD 810, Method 509 Salt Fog Testing is performed to evaluate the effectiveness of protective coatings and finishes on materials, ingress of moisture into connectors and sealed components. Salt Fog Testing does not correlate to field life, but it provides an indication of potential problem areas associated with exposure to the salt (marine) environment. The latest revision is Method 509.7 from MIL-STD-810H.

Ensuring Durability with Comprehensive Corrosion Testing

Salt is one of the most pervasive substances in the world, found in oceans, the atmosphere, ground surfaces, lakes, and rivers. It is impossible to avoid. Performing corrosion testing to exacting standards is crucial for product durability. Exposure to a salt corrosive atmosphere can lead to several detrimental effects, including:

Corrosion Effects

Corrosion due to electrochemical reaction
Accelerated stress corrosion
Formation of acidic/alkaline solutions following salt ionization in water

Electrical Effects

Impairment of electrical material due to salt deposits
Production of conductive coatings
Corrosion of insulating materials and metals

Physical Effects

Clogging or binding of moving parts of mechanical components and assemblies
Blistering of paint because of electrolysis

MIL-STD-810 Salt Fog Testing Procedures

MIL-STD-810 Salt Fog Testing is performed in a specially constructed chamber. DES has one of the leading brands of a salt fog testing chambers. MIL-STD-810 requires a 5% (±1%) by weight salt solution dissolved in water with a pH between 6.5 to 7.2. The salt solution is atomized into the chamber as a fine wet salt fog or mist while the air temperature in the chamber is maintained at 35 ±2 °C (95 ±3.6 °F). Two collection receptacles are placed inside of the chamber to measure the salt fog fallout rate. The fallout rate is required to be 1 to 3 ml per hour for each 80 cm² of horizontal collecting area.

Test samples should be configured and oriented as they would normally be stored, shipped, or used. The recommended duration is 48 hours of salt fog exposure followed by 48 hours of drying in ambient air with less than 50% humidity. An alternating 24 hour test cycle (24 fog, 24 drying, 24 fog, 24 drying) has proven to be more destructive and is the way the MIL-STD-810 Salt Fog Test is most commonly run. After the test, the samples are inspected for physical, electrical and corrosion effects.

MIL-STD-810 Humidity Testing

MIL-STD-810, Method 507 Humidity Testing applies to items that are stored or deployed in warm, humid atmospheres. The purpose of Method 507 Humidity Testing is to determine a product’s resistance to warm, humid environments. It is intended to provide an indication of potential problems associated with humidity. MIL-STD-810 Humidity testing provides stressful conditions intended to reveal potential problem areas in material. It does not attempt to duplicate the complex temperature/humidity environment. The latest revision is Method 507.6 from MIL-STD-810H.

MIL-STD-810 Method 507 Humidity Testing consists of two procedures, Procedure I – Induced and Natural Cycles and Procedure II – Aggravated.

Adapting to Humid Environments: MIL-STD-810 Testing

Procedure I contains three natural cycles for test items that are open to the environment and three induced (storage and transit) cycles. The natural humidity cycles are Constant high humidity (Cycle B1), Cyclic high humidity (Cycle B2), and Hot-humid (Cycle B3). The induced (storage and transit) cycles are Induced constant high humidity (Cycle B1), Induced variable – high humidity (Cycle B2), and Induced hot-humid (Cycle B3).

Constant high humidity (Cycle B1) represents conditions in heavily forested tropical regions where nearly constant temperature and humidity prevails during rainy and wet seasons with little solar radiation exposure. Cyclic high humidity (Cycle B2) conditions occur in tropical areas where solar radiation is a factor. Hot-humid (Cycle B3) is unique to materiel that is deployed specifically in the Persian Gulf or Red Sea regions. It is not to be used as a substitute for worldwide exposure requirements where B1 or B2 would apply.

Induced constant high humidity (Cycle B1) is defined as a humid environment with relative humidity above 95 percent with nearly constant 27 °C (80 °F) temperature for periods of a day or more. Induced variable – high humidity (Cycle B2) conditions occur when material in the cyclic high humidity environment category receives heat from solar radiation with little or no cooling air. Induced hot-humid (Cycle B3) exists when items in the hot -humid category receive heat from solar radiation with little or no cooling air.

The test durations for Procedure I are listed in Table 507.6-II from MIL-STD-810H.

high humidity environments table from mil std 810h standard

Procedure II – Aggravated contains more extreme temperature and humidity levels than those found in nature but requires shorter durations. The advantage of Procedure II is that it produces the effects of temperature-humidity faster than the natural or induced procedures identifying potential problems quicker. The aggravated 24 hour temperature-humidity cycle from MIL-STD-810H is shown in Figure 507.6-7. Although the combined 60 °C (140 °F) and 95 percent RH does not occur in nature, this combination of temperature and relative humidity has historically proven to reveal potential defects in most material. The minimum number of 24-hour aggravated cycles for the test is ten preceded by a 24 hour preconditioning step.

Oxidation and/or galvanic corrosion of metals.
Increased chemical reactions.
Chemical or electrochemical breakdown of organic and inorganic surface coatings.
Changes in friction coefficients, resulting in binding or sticking.
Swelling of materials due to sorption effects.

MIL-STD-810 Solar (Sunshine) Radiation Testing

The purpose of MIL-STD 810, Method 505 Solar Radiation Testing is to evaluate the heating effects of solar radiation on materiel and to identify the actinic (ultraviolet photo degradation) effects of exposure to solar radiation. The latest revision for radiation testing is Method 505.7 from MIL-STD-810H.

Solar Heating can cause some of the following failures:

Jamming or loosening of moving parts.
Weakening of solder joints and glued parts.
Changes in strength and elasticity.
Loss of calibration or malfunction of linkage devices.
Loss of seal integrity.
Changes in electrical or electronic components.
Premature actuation of electrical contacts.
Changes in characteristics of elastomers and polymers.
Blistering, peeling, and de-lamination of paints, composites, and surface laminates.
Softening of potting compounds.
Pressure variations.
Sweating of composite materials.
Difficulty in handling.

Solar Radiation can cause additional failures such as:

Fading of labels, fabric, and plastic color.
Chalking and fading of paints.
Deterioration of plastics through photochemical reactions initiated by shorter wavelength radiation.

MIL-STD-810H Tests for Solar Radiation

MIL-STD-810 Method 505 Solar Radiation has two procedures: Procedure I Cycling and Procedure II Steady State.

Procedure I is meant to investigate the effects of heat produced by solar radiation by exposing products to 24-hour cycles of simulated solar radiation at realistic maximum levels typical throughout the world. It contains two 24-hour cycles to choose from, A1 and A2. Category A1 represents the hottest conditions in the most extreme month at the most severe locations throughout the world that experience high temperatures accompanied by high levels of solar radiation. Category A2 represents less severe conditions at locations that experience high temperatures accompanied by high levels of solar radiation, winds, and moderately low humidity, namely, the most southerly parts of Europe, most of the Australian continent, south central Asia, northern and eastern Africa, coastal regions of north Africa, southern parts of the US, and most of Mexico. The minimum duration for either cycle is three. If the maximum peak response temperature from the previous 24-hour cycle is not reached during three cycles, continue cycling until repeated peak temperatures are reached, or for seven cycles, whichever comes first.

Procedure II is used to evaluate the actinic or photo degradation effects when items are exposed to long periods of sunshine. It uses intensified solar loading to accelerate actinic effects. Procedure II produces an acceleration factor of approximately 2.5 times the solar energy experienced in one 24-hour (natural) diurnal cycle plus a 4-hour lights-off period to allow for alternating thermal stressing. The recommended minimum durations for Procedure II are (10) 24-hour cycles for products that are occasionally used outdoors and (56) 24-hour cycles for products continuously exposed to outdoor conditions.

Consider the following when determining which procedure and MIL-STD 810H test levels to use for solar radiation testing:

The operational purpose of the test item.
The anticipated areas of deployment.
The test item configuration.
The anticipated exposure circumstances (use, transportation, storage, etc.).
The expected duration of exposure to solar radiation.
The expected problem areas within the test item.
