Description / Abstract:


To define terms used in the environmental testing of specimens of electrotechnical products, such as components, sub-assemblies, assemblies and equipments.

The environmental conditions for which provision is made include shock and vibration, climatic (temperature, humidity and air pressure), sealing (against ingress of solids, liquids and gasses or to maintain a pressure difference), soldering heat (including thermal shock from soldering).

Terms for fire hazard testing are not included as they are to form a part of IEC 695. The following conditions have not been considered : solar radiation, mould growth, corrosion, robustness of terminations, durability of marking, dust, sand and rain, nuclear radiation, acoustically induced vibration.


1 The scope of IEC 68 is in clause 2 of IEC68-1. In other standards of IEC 68, clause 1 is termed the "object" clause and serves the purpose of object and field of application.

2 This guide uses, in principle, existing terms and definitions from IEC 68 listed according to a classification of environmental conditions that is not that of IEC 721 but is better suited to the needs of IEC 68-2 test methods.

3 Some definitions from specialized vocabularies, for example from IS0 2041 and IEC 721-1, have been included where there is no definition in IEC 68. This standard identifies the relation between the definitions given and those other sources.
