MIL-STD-810 Temperature Shock Testing

Method 503 in MIL-STD-810 covers procedures for temperature shock or thermal shock testing. Temperature shock testing (as defined in MIL-STD-810H) is a rapid change in air temperature greater than 10°C (18°F) per minute. Temperature shock testing is used to determine if products can withstand sudden changes in the surrounding temperature environment without experiencing physical damage or deterioration in performance. The latest revision is Method 503.7 from MIL-STD-810H.

Some of the Effects of Temperature Shock Environments are:

Shattering of glass and optical material.
Binding or slackening of moving parts.
Differential contraction or expansion rates or induced strain rates of dissimilar materials.
Deformation or fracture of components.
Cracking of surface coatings.
Leaking of sealed compartments.
Failure of insulation protection.
Changes in electrical and electronic components.
Electronic or mechanical failures due to frost formation.

Method 503 Has One Procedure with Four Variations:

Procedure I-A – One-way Shock(s) from Constant Extreme Temperature.
This procedure is for material that is only rarely exposed to thermal shock in one direction. At least one shock is performed from low to high temperature, or vice versa.
Procedure I-B – Single Cycle Shock from Constant Extreme Temperature. For items that are exposed to only one thermal shock cycle (one in each direction). One shock is performed from low-to-high temperature (or vice versa) and then one shock in the opposite direction.
Procedure I-C – Multi-Cycle Shocks from Constant Extreme Temperature. A minimum of three shocks are performed at each condition, i.e., three transfers from cold to hot, three transfers from hot to cold, and a stabilization period after each transfer.
Procedure I-D – Shocks to or from Controlled Ambient Temperature. Procedure I-D follows the durations of Procedures I-A to I-C, except all shocks are to and/or from controlled ambient temperatures.

Test levels for MIL-STD-810 Temperature Shock Testing

Consider the following typical conditions from MIL-STD-810H:

Aircraft flight exposure. For materiel exposed to desert or tropical ground heat with possible direct solar heating, then, immediately afterwards, exposed to the extreme low temperatures associated with high altitude. The item could be subjected to multiple thermal shocks occurring in multiple missions.
Air delivery – desert. For products that are delivered over desert terrain from unheated, high altitude aircraft, then exposed to hot ambient air temperature (no solar loading).
Ground transfer – ambient to or from either cold regions or desert. For items that move from a controlled ambient indoor environment or enclosure to a cold region or desert environment.

For MIL-STD-810 temperature shock testing, the transfer time between the temperatures should be within one minute. The test sample is soaked for as long as necessary to ensure a uniform temperature throughout at least its outer portions. If the Life Cycle Environmental Profile indicates a duration less than that required to achieve stabilization, this duration should be used. If the critical point of interest is near the surface of the item, a shorter duration may apply rather than complete stabilization of the item.

MIL-STD-810 Low Temperature Testing

MIL-STD 810, Method 502 Low Temperature Testing is used to evaluate the effects of low temperatures on cold storage, operation, and manipulation. Method 502 is applicable for testing products that will be exposed to cold temperatures during their life cycle. The latest revision is Method 502.7 from MIL-STD-810H.

MIL-STD-810 low temperature testing is not intended to simulate a high altitude, low temperature environment associated with an unpressurized aircraft at altitude. However, it may be used in combination with Method 500.6 to simulate a high altitude, low temperature environment.

Some of the Effects of Low Temperature Environments are:

Hardening and embrittlement of materials.
Binding of parts from differential contraction of dissimilar materials.
Loss of lubrication and lubricant flow due to increased viscosity.
Changes in electronic components (resistors, capacitors, etc.).
Changes in performance of transformers and electromechanical components.
Stiffening of shock mounts.
Cracking, change in impact strength, and reduced strength.
Effects due to condensation and freezing of water in or on the materiel.

Method 502 Has Three Procedures Starting with Low Temperature Storage:

Procedure I – Storage. Procedure I is used to evaluate products that are stored at Low temperatures. After the Low temperature storage test is completed, an operational test at ambient conditions is performed.
Procedure II – Operation. Procedure II is used to determine how well an item will operate in low temperature environments. Operation during this procedure assumes minimum contact by personnel.
Procedure III – Manipulation. Manipulation is used to investigate the ease with which the materiel can be assembled, operated, and disassembled by personnel wearing heavy, cold-weather clothing. In addition, this could also include maintenance procedures.

Low Temperature Test Parameters and Procedures Under MIL-STD-810

First, identify the Low temperature test parameters and applicable procedures. DES can help determine the appropriate low temperature test conditions based on the equipment’s intended use. Consider the following cold temperatures in various world-wide locations from Table 502.7-I. (MIL-STD-810H):

Design Type	Location	Ambient Air Temperature ^oC(^oF)	Induced Environment Temperature (Storage & Transit) ^oC(^oF)
Basic Cold (C1)	Most of Europe; Northern contiguous US; Costal Canada; High-Latitude coasts (e.g., southern coast of Alaska); High elevations in lower latitudes	-21 to -32 (-5 to -25)	-25 to -33 (-13 to -28)
Cold (C2)	Canada, Alaska (excluding the interior); Northern Scandinavia; Northern Asia (some areas), High Elevations (Northern and Southern Hemispheres); Alps; Himalayas; Andes	-37 to -46 (-35 to -50)	-37 to -46 (-35 to -50)
Severe Cold (C3)	Interior of Alaska; Yukon (Canada); Interior of Northern Canadian Islands; Greenland ice cap; Northern Asia	-51 (-60)	-51 (-60)

Source: Table 502.7-I. (MIL-STD-810H)

The recommended test duration from MIL-STD-810H is four hours after stabilization for nonhazardous or non-safety-related (non-life-support type) material. Munitions, rubber and plastics may continue to deteriorate following low temperature stabilization. For these items, a minimum duration of 72 hours following temperature stabilization is recommended. For restrained glass, ceramics, and glass-type products (such as those used in optical systems, laser systems, and electronic systems) a minimum storage period of 24 hours following temperature stabilization is recommended.

MIL-STD-810 High Temperature Testing

MIL-STD 810, Method 501 High Temperature Testing is used to evaluate the effects of high temperature conditions on performance, materials, and integrity. Method 501 is applicable for temperature testing products that are deployed in areas where temperatures (ambient or induced) are higher than standard ambient. Note, the latest revision of this method is 501.7 from MIL-STD-810H.

Method 501 is limited to evaluating the effects of relatively short-term (months, as opposed to years), even distributions of heat throughout the test item. This method is not typically practical for evaluating materials where solar radiation produces thermal gradients or photochemical effects. Method 505 is used to test the effects of solar radiation. It is also not practical to evaluate degradation that occurs from continuous long-term exposure to high temperatures where synergetic effects may be involved.

The following are typical failures that could occur from products used in high temperature environments.

Parts bind from the differential expansion of dissimilar materials.
Lubricants become less viscous; joints lose lubrication by the outward flow of lubricants.
Materials change in dimension.
Packing, gaskets, seals, bearings, and shafts become distorted, bind, and fail causing mechanical failures.
Gaskets display permanent sets.
Closure and sealing strips deteriorate.
Fixed-resistance resistors change in values.
Electronic circuit stability varies with differences in temperature gradients and differential expansion of dissimilar materials.
Transformers and electromechanical components overheat.
Operating/release margins of relays and magnetic or thermally activated devices alter.
Shortened operating lifetimes.
High pressures are created within sealed cases (batteries, etc.).
Discoloration, cracking, or crazing of organic materials.
Out-gassing of composite materials or coatings.
Failure of adhesives.

MIL-STD-810 Method 501 Tests: High Temperature Procedures

Procedure I – Storage. Procedure I is for testing products that are stored at high temperatures. After the high temperature storage test is completed, an operational test at ambient conditions is performed. Procedure I can be either a cyclic temperature test or a constant temperature test.
Procedure II – Operation. Procedure II is used to investigate how high temperatures could affect the performance of items while they are operating. Temperature Procedure II can be performed as either a cyclic temperature test or a constant temperature test.
Procedure III – Tactical-Standby to Operational. This temperature procedure evaluates the material’s performance at normal operating temperatures after being presoaked at high non-operational temperatures. An example of Procedure III is a product that is stored in an enclosed environment that develops high internal temperatures before being removed and then operated in a relatively short period of time.

What is the procedure for MIL-STD-810 High Temperature Testing?

First, identify the high temperature levels, test conditions, and applicable procedures. DES can help determine the appropriate temperature ramp rates and durations of the tests based on the equipment’s intended use and the operating environmental conditions. Consider the following climatic temperatures from Table 501.7-I. (MIL-STD-810H):

Design Type	Location	Ambient Air ^oC (^oF)	Induced² ^oC (^oF)
Basic Hot (A2)	Many parts of the world, extending outward from the hot dry category of southwestern United States, northwestern Mexico, central and western Australia, Saharan Africa, South America, Southern Spain, and southwest and south central Asia.	30 – 43 (86 – 11)	30 – 63 (86 – 145)
Hot Dry (A1)	Southwest and south central Asia, southwestern United States, Saharan Africa, central and western Australia, and northwestern Mexico.	32 – 49 (90 – 120)	33 – 71 (91 – 160)

Table 501.7-I from MIL-STD-810H

Next, determine whether a constant temperature test or a cyclic temperature test is appropriate. Constant temperature testing is used only for items situated near heat-producing equipment or when it is necessary to verify the operation of an item at a specified constant temperature. The duration for constant temperature test temperature is at least two hours following test specimen stabilization.

For cyclic exposure, there are two 24-hour cyclic profiles contained in Tables 501.7-II and 501.7-III. The number of cycles for the Procedure I storage test is a minimum of seven to coincide with the one percent frequency of occurrence of the hours of extreme temperatures during the most severe month in an average year at the most severe location. The minimum number of cycles for the Procedure II operational testing is three. This number is normally sufficient for the test item to reach its maximum response temperature.

Method 500 is not intended for items that are installed or operated in space vehicles, aircraft, or missiles that fly at altitudes above 21,300 m (70,000 ft).

The following are typical failures that could occur from products used in a high altitude (low pressure) environment:

Leakage of gases or fluids from gasket-sealed enclosures
Deformation, rupture, or explosion of sealed containers
Change in physical and chemical properties of low-density materials
Overheating of materiel due to reduced heat transfer
Evaporation of lubricants
Erratic starting and operation of engines
Failure of hermetic seals
Erratic operation or malfunction of materiel resulting from arcing or corona

MIL-STD-810 Method 500.6 Insights for Low Pressure Testing

MIL-STD-810 Method 500.6 has four procedures:

Procedure I – Storage/Air Transport. Procedure I is for testing material that is transported or stored at high ground elevations or transported by air in its shipping/storage configuration.
Procedure II – Operation/Air Carriage. Procedure II is used to test the performance of products operated at high altitudes. It may be preceded by Procedure I.
Procedure III – Rapid Decompression. Procedure III is for determining if a rapid decrease in cabin pressure will cause a failure or malfunction that would endanger nearby personnel the ground vehicle or the aircraft in which it is being transported.
Procedure IV – Explosive Decompression. Procedure IV is similar to Procedure III except that it involves an instantaneous decrease in pressure.

How is MIL-STD-810 Low Pressure Testing performed? First, it is necessary to determine the test parameters such as test altitude (pressure) and temperature, rate of change of pressure (and temperature if appropriate), duration of exposure, and test item configuration based upon the Life Cycle Environmental Profile. Once the parameters are defined, low pressure testing is performed by placing the specimen in a specialized chamber that simulates altitude by controlling pressure and temperature. Upon completion of the altitude test, DES will promptly deliver a detailed test report that includes the customer’s name and address, the test dates, a summary of the test procedure, equipment & measuring system calibration information, plots of altitude and temperature, test observations & results, color pictures of the altitude test setup and color pictures of any failures.

Electrical Connector Testing: Ensuring Reliability in Vibrating Environments

Electrical connectors are ubiquitous components in the world of electronics, serving as the vital links that enable seamless communication and power transmission within electronic systems. In today’s rapidly advancing technological landscape, ensuring the integrity and reliability of electrical connectors is of paramount importance. Some are exposed to harsh vibration environments such as automotive, aerospace, military, missiles, and rockets.

A failure or intermittent connection can cause a fault, malfunction, or a system shutdown in a complicated electronic system. These demanding applications leave no room for error, as even a minor fault or intermittent connection can lead to catastrophic consequences, including system failures, malfunctions, or complete shutdowns. Electrical connector testing includes shock testing, mechanical load testing, and vibration testing, among others.

In this article, we will review the methodologies and standards for effective electrical connector testing in vibrating environments.

Mixed Mode, Random and Sinusoidal Vibration Testing of Electrical Connectors

Electrical connector vibration tests mimic real-world scenarios. Understanding how connectors perform under these complex conditions is crucial for designing robust systems.

How is Electrical Connector Vibration Testing performed?

The specific tests performed on electrical connectors include random, mixed mode, and sinusoidal vibration testing. (See below for links to other blog articles that explain more about the types of vibrations.) The test equipment consists of an electrodynamic shaker that has an armature or head which produces the required excitations. A computerized controller sends the precise vibration signals to an amplifier which boosts the signals to drive the shaker head.

Accelerometers are used to measure the test vibrations and to provide feedback to the controller. The connectors are mounted to a rigid test fixture that is attached to the armature, a slip table or head expander. Proper test fixture design is important so that resonances do not occur. Also, proper mounting of the connectors is important to ensure they are supported sufficiently, and that relative motion does not occur due to poor mounting.

The vibration test is run at specified frequencies, amplitudes, durations according to the chosen military, automotive, aerospace, etc. specifications. During the test, the connectors are monitored for discontinuities using an event detector that can monitor discontinuities as quickly as 0.1 microseconds. After testing is completed, the connectors are inspected for wear and failures.

DES will promptly deliver a detailed test report that includes the customer’s name and address, the test dates, a summary of the test procedure, equipment & measuring system calibration information, operational test data, test observations & results, color pictures of the vibration test setup and color pictures of any failures.

Why Perform Electrical Connector Vibration Testing?

The reasons behind subjecting electrical connectors to such rigorous testing are multifaceted. As mentioned above, it helps in identifying potential issues that could lead to field failures and in the development of connectors that can maintain performance in challenging settings. More specific reasons include the following:

Evaluating Performance and Reliability: Vibration testing assesses how well electrical connectors perform and maintain their reliability in diverse vibration environments.
Detecting Discontinuities: The testing procedure aims to identify if electrical discontinuities occur when connectors are subjected to typical usage vibrations.
Preventing Field Failures: By simulating real-world conditions, it aids in the prevention of field failures caused by issues like fretting fatigue, plating wear, cracks, broken wires, intermittent discontinuities, or loose components.
Developing Robust Connectors: Vibration testing is instrumental in the development of stronger and more robust connectors suitable for demanding applications in sectors such as automotive, military, and space industries.

EIA-364-28 and other Electrical Contractor Vibration Test Standards

Adherence to industry standards is paramount when performing electrical connector testing in vibration environments. These standards provide comprehensive guidelines and procedures for conducting rigorous testing. They emanate from a variety of organizations such as the EIA-364-28 standard from the Electronics Industries Alliance. Here are some of the prominent standards employed in the evaluation of electrical connectors’ vibrational resilience:

EIA-364-28 – Vibration Test Procedure for Electrical Connectors and Sockets
GMW 3191 – Automotive Connector Test and Validation Specification
MIL-STD-1344A, Method 2005 – Military Standard, Test Methods for Electrical Connectors
SAE USCAR-2 – Performance Specification for Automotive Electrical Connector Systems

Understanding IEC 60068-2: A Comprehensive Guide

IEC 60068-2 is a globally recognized standard that outlines a series of tests for products, components, and equipment to assess their ability to withstand environmental conditions. By simulating the different climatic conditions and mechanical stresses a product can undergo during its lifetime, environmental testing can help manufacturers validate the ruggedness, durability, and performance of their products.

One of the key tests within this series is the shock test, which is designed to simulate the effects of sudden impacts or abrupt changes in motion that a product might encounter during its lifecycle. Specifically, the International Electrotechnical Commission (IEC) manages two well-known shock and drop-shock standards for electrical and electronic-related technologies, IEC 60068-2-27 and IEC 60068-2-31.

IEC 60068-2-27 Environmental testing Part 2-27: Test Ea: Shock
IEC 60068-2-31 Environmental testing Part 2-31: Test Ec: Rough Handling Shocks

IEC 60068-2 shock testing is a critical part of product development for several reasons:

Real-world conditions simulation: Products often encounter shocks and impacts during shipping, handling, and everyday use. IEC 60068-2 shock testing simulates these conditions to assess how well the product can withstand them.

Identification of potential weaknesses: Shock testing can reveal design or manufacturing flaws that might cause the product to fail prematurely. Identifying these issues early in the development process can save time and money on product recalls or redesigns.

Ensuring product reliability: For products that are used in critical applications, such as medical devices or aerospace components, shock testing is crucial to ensure they can perform reliably under all conditions.

Worldwide recognition: IEC 60068-2 is an international standard, so products tested to this standard are accepted worldwide. This can simplify the process of selling your product in international markets.

At DES, we understand the importance of detailed and accurate shock testing. Our experienced team can guide you through the process, ensuring your product meets all relevant standards and is ready for the rigors of real-world use.

IEC 60068-2-27: A Detailed Look at the Shock Testing Standard

IEC 60068-2-27 is a specific test within the IEC 60068-2 series that focuses on shock testing. This test is designed to simulate the shock conditions that products, components, and equipment may encounter during transportation, storage, handling, or in use. The purpose of this test is to reveal mechanical deficiencies, degradation, and/or accumulate damage caused by shocks.

The IEC 60068-2-27 test is a crucial part of the product development process. It provides manufacturers with valuable insights into the potential weaknesses of their products, allowing them to make necessary improvements to enhance product durability.

The test involves subjecting the product to specified levels of shock impulses in a controlled environment. There are 3 types of shocks in IEC 60068-2-27, half-sine impulse, saw-tooth impulse, and the trapezoidal impulse. Much of this standard defines the pulse shapes and control of the shock parameters. Other sections cover the test severities such as the peak acceleration level, duration, and number of shocks. The user specifies which test severities are applicable to their products. Annex A provides guidance and examples of test severities for various applications. Annex B gives information about shock response spectra (SRS) and the characteristics of the pulse shapes. The product’s performance may be evaluated during the shocks or just before/after the test.

At Delserro Engineering Solutions, we have extensive experience conducting IEC 60068-2-27 shock testing. Our meticulous approach to testing ensures that your product is thoroughly evaluated for potential weaknesses, providing you with the information you need to make informed decisions about product improvements.

IEC 60068-2-31: Shocks Intended to Simulate Rough Handling

IEC60068-2-31 is another critical standard within the IEC 60068-2 series, focusing on simulating the effects of rough handling shocks. Rough handling shocks are knocks, jolts, and falls typically encountered during repair work, rough handling or dropping. IEC 60068-2-31 defines 3 types of rough handling shock tests:

Drop and Topple is intended to assess the effects of knocks or jolts typically occurring during repair work or rough handling on a table or work-bench. The drop tests are accomplished by raising an edge or corner of an item to a prescribed height, then releasing it allowing the face under test to drop onto a hard surface. The topple test is performed by raising an edge slowly until instability occurs, then allowing the specimen to topple over onto an adjacent face. The number of drops or topples is usually 4.
Free Fall – Procedure 1 is aimed at evaluating the effects of falls from rough handling. The entire specimen is raised to a defined height, then released allowing it to free fall onto a hard surface. The product can be oriented to allow the impact to occur on a face, edge or corner. Typically the number of free falls is 2.
Free Fall – Procedure 2 is intended to reproduce repetitive shock conditions likely to occur on component-type specimens such as electrical connectors. The test specimens are subjected to a prescribed number of falls from a specified height onto a hard surface. The number of falls in procedure 2 typically ranges from 50 to 1,000.

At Delserro Engineering Solutions, we use a thorough approach when conducting IEC 60068-2-27 and IEC 60068-2-31 shock testing, ensuring that the test is performed under repeatable conditions and your product is evaluated for rugged usage.
