IS 9001 (Part 2) : 1977 'Guidance for environmental testing: Part 2 Cold and dry heat tests' was published in 1977 and was based on IEC publication 60068-3-1 : 1974, which was further superseded by IS/IEC 60068-3-1 : 2011 which was based on IEC 60068-3-1 : 2011. The first revision of this standard has been undertaken to align it with the latest version of IEC 60068-3-1 : 2023.
The text of IEC standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are however not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appears referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
