Foreword

See Annex NA for the parts of GB/T 2423 "Environmental testing for electric and

electronic products - Part 2.Test methods".

This Part is Part 60 of GB/T 2423.

This Part identically adopts IEC 60068-2-21.2006 "Environmental testing - Part 2-21.

Tests - Test U. Robustness of terminations and integral mounting devices" (English

version). It only made the following editorial modifications.

- modified "this Part of IEC 60068" to "this Part of GB/T 2423" or "this Part";

- used decimal point "." to replace comma "," that is used as decimal point;

- deleted the foreword of the international standard;

- added the informative Annex NA.

Annex A, Annex NA of this Part are informative.
