IEC 60068

IEC 60068 is an international standard for the environmental testing of electrotechnical products that is published by the International Electrotechnical Commission (IEC). IEC 60068 is a collection of methods for environmental testing of electronic equipment and products to assess their ability to perform under environmental conditions including extreme cold and dry heat.  IEC 60068 offers appropriate severities and prescribes various environmental conditions for measurements and tests.

IEC 60068 has three parts:

• IEC 60068-1: General and guidance
• IEC 60068-2: Tests
• IEC 60068-3: Supporting documentation and guidance
