IEC 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 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 , IEC and IEC 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.

IEC Cold This testing is aimed to determine the ability of equipment or components to be used, stored or transported at low temperature. This method uses constant cold temperature conditions. IEC Dry heat This test investigates how well equipment or products perform when being used, transported or stored at high temperatures. This method uses constant hot temperature conditions, dry heat.

IEC Solar radiation testing 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 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 test is aimed at determining mechanical weaknesses or degradation. IEC exposes specimens to sinusoidal vibrations over a specified frequency range for a specified duration.

IEC Acceleration steady state IEC evaluates the structural integrity and the satisfactory performance of products that would experience steady or constant acceleration forces. The test duration varies depending upon the severity. It is useful for evaluating the corrosion resistance of paints and protective coatings.

IEC Low air pressure The object of IEC 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 Change of temperature This method is designed to determine if equipment or products can withstand rapid changes in temperature.

IEC Shock IEC is intended for equipment or products that could be subjected to infrequent or repetitive shocks during storage, use or transportation. 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 provides guidance for the test severity and the shape of the shock pulse vs.

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. 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 for small, low mass specimens where itis difficult to produce condensation on the surface of the specimen.

IEC Rough handling shocks IEC 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.

IEC is primarily intended for component type specimens. Products are required to function without significant degradation. The combined environments may have adverse effects on components and gaskets.

IEC Test Kb: Salt mist, cyclic IEC uses a 2 part repeating cycle of salt mist spray , followed by high humidity at elevated temperature. 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.

IEC Loose cargo testing, including bounce IEC provides methods for determining the ability of a specimen to withstand specified severities of bounce, e. Products are typically tested in their packaged configuration or in a transit case. IEC Vibration, broadband random 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. 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 Damp heat, steady state IEC 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.

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.

It is intended for for components, equipment and products that may experience complex transient shocks. For more information about SRS Testing, please see our blog article.
