IEC60068 is an internationally recognized standard developed by the International Electrotechnical Commission. IEC 60068 is a collection of methods for environmental testing of electronic equipment, components and electromechanical products to assess their ability to perform and survive under conditions such as transportation, storage, operational environments, extreme cold and heat. IEC 60068 offers appropriate severities and prescribes various environmental conditions for measurements and tests in each test method. The below procedures in this standard provide a series of reproducible test methods. It is typical for companies to test their products to one or many of the standards below.

The specimens can be heat-dissipating or non-heat dissipating for test methods using constant temperature conditions such as IEC 60068-2-1, IEC 60068-2-2 and IEC 60068-2-78. A heat-dissipating subject is one where the hottest point of its surface measured in free conditions is greater than 5K higher than the ambient temperature of the surrounding atmosphere once the temperature stability has been achieved.

This method evaluates the anticipated effects of solar radiation on ground level products. It specifies ways of testing equipment or components under simulated solar radiation conditions and investigates how much effect solar radiation has on equipment in the presence of moisture. IEC 60068-2-5 specifies two testing methods, test method Sa: thermal effect test, and test method Sb: weathering test. Method Sa involves irradiating specimens in a test chamber under controlled temperature and humidity. Method Sb incorporates water spray.

The object of IEC 60068-2-13 is to investigate the ability of equipment or products to be used, stored or transported under low air pressure conditions at room temperature. This testing is also called altitude testing.

IEC 60068-2-27 is intended for equipment or products that could be subjected to infrequent or repetitive shocks during storage, use or transportation. It is designed to uncover mechanical weaknesses and/or degradation caused by those shocks. Products are usually tested in an unpackaged condition, but can be tested in their transport case when the latter may be considered to be part of the specimen.

IEC 60068-2-27 provides guidance for the test severity and the shape of the shock pulse vs. product application in Annex A. Whenever possible, the test severity and the shape of the shock pulse should reproduce the effects of the actual environment to which the specimen will be subjected, or to satisfy the design requirements if the goal is to assess structural integrity.

This test looks at how products/equipment hold up during use, storage or transport under conditions of high humidity combined with cyclic changes in temperature. The temperature/humidity cycles in this method typically produce condensation on the surface of the specimen. Specimens should be evaluated in their packaging if the test is being used to verify their performance while being transported or stored in packaging. Consider the use of IEC 60068-2-38 for small, low mass specimens where itis difficult to produce condensation on the surface of the specimen.

IEC 60068-2-31 is a test procedure for simulating the effects of rough handling shocks, knocks, jolts and falls which may occur during repair work or rough handling in operational use. It is intended primarily for electronic equipment. This method does not simulate the effects of shocks received during transportation as loosely constrained cargo.

This method provides procedures for testing equipment or components under combined temperature or temperature/humidity with low air pressure. Products are required to function without significant degradation. The combined environments may have adverse effects on components and gaskets.

IEC 60068-2-52 uses a 2 part repeating cycle of salt mist (spray), followed by high humidity at elevated temperature. It is designed to evaluate whether products/equipment can withstand exposure to a salt-heavy atmosphere, as salt can degrade certain products/materials. The first part of the cycle is a wet or salt mist exposure for 2 hours. The humidity portion of the cycle is either 7 days or 20 to 22 hours depending on the test severity. The number of cycles required depends on the test severity. Afterwards, there is a three-day storage period at 21C to 25C and 45% to 55% humidity.

IEC 60068-2-55 provides methods for determining the ability of a specimen to withstand specified severities of bounce, e. g. when transported as loose cargo on wheeled vehicles. Products are typically tested in their packaged configuration or in a transit case.

This test deals with broadband random vibration, looking at equipment and products that may undergo vibrations that are random in nature. Random vibrations occur in shipping transportation and operational environments such as aircraft, space vehicles and land vehicles. IEC 60068-2-64 evaluates whether specimens can withstand dynamic loads without unacceptable degradation of their functional and/or structural integrity when subjected to specified random vibrations. This standard is primarily intended for unpackaged specimens. Products may be tested in their transportation container when this is considered to be part of the specimen.

IEC 60068-2-78 evaluates whether products or equipment can withstand transportation, storage and use under conditions of high temperature and humidity. The test conditions are high humidity at constant temperature without condensation on specimens over a prescribed period. It applies to small equipment or components, large equipment, and applies to both heat-dissipating and non-heat-dissipating specimens.

The purpose of the test is to determine whether products can resist mixed mode vibration excitation without degradation of their functional and/or structural performance. Mixed more vibrations occur in helicopters and tracked vehicles such as tanks. This method is primarily intended for electronic or electromechanical type specimens, however it is not restricted to such products.

IEC 60068-2-81 specifies test methods using a synthesized shock response spectrum (SRS). It is intended for for components, equipment and products that may experience complex transient shocks. This test method centers on the use of SRS and techniques associated with SRS.

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 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.
