Environmental testing - Part 3-1 : supporting documentation and guidance - Cold and dry heat tests
IEC 60068-3-1:2011 provides guidance regarding the performance of cold and dry heat tests. This second edition cancels and replaces the first edition, published in 1974, and constitutes a technical revision. The main changes with regard to the previous edition are as follows: - removal of guidance regarding thermal characteristics of chamber walls; - revision of sections that address environmental chambers that do not use movement of air for temperature control.
