Foreword
GB/T 2423 “Environmental testing for electric and electronic products - Part 2: Tests”
is divided into several parts according to the test methods.
This Part is Part 57 of GB/T 2423.
This part is identical to IEC 60068-2-81:2003 (Ed. 1.0) “Environmental testing - Part
2-81: Tests - Test Ei: Shock - Shock response spectrum synthesis”.
For convenience of use, this Part makes the following editorial changes:
a) Change the word “this part of IEC 60068” to “this part of GB/T 2423” or “this
part”;
b) Use the decimal point “.” to replace the comma “,” as a decimal point;
c) Delete the foreword of the international standard;
d) Change this part to the current name, in order to be consistent with the names of
other parts of the existing GB/T 2423.
Some of the normative documents cited in this part have not yet been converted into
equivalent national standards, and are still listed with IEC/ISO numbers when these
normative documents are cited.
Appendix A, Appendix B, Appendix C and Appendix D of this part are informative
annexes.
This Part was proposed and managed by the National Technical Committee 8 on
Environmental Conditions of Electric and Electronic Products and Environmental Test
of Standardization Administration of China (SAC/TV 8).
The drafting organizations of this Part: Shanghai Institute of Quality Inspection and
Technical Research, The Fifth Institute of Electronics, Ministry of Information Industry,
Zhongyuan Micro Instrument Co., Ltd., Shanghai Institute of Process Automation
Instrumentation, Guangzhou University, Beijing University of Aeronautics and
Astronautics, Shanghai Spaceflight Precision Machinery Institute, Shanghai Aerospace
808.

Zhonggen, Li Chuanri, Hu Weixin, Yang Chuan, Cao Xuefeng, Wang Qunjian.
Environmental testing for electric and electronic products -
Part 2: Tests - Test Ei: Shock - Shock response spectrum
synthesis
1 Scope
This part of GB/T 2423 specifies tests using a synthesized shock response spectrum
(SRS). It is intended for general application to specimens when simulation of transient
excitation of a complex nature is required.
