Foreword
In accordance with test methods, GB/T 2423 Environmental Testing - Part 2.Tet
Methods is divided into several parts.
This is the 35th part of GB/T 2423.
This Part was drafted in accordance with the rules in GB/T 1.1-2009.
This Part serves as a replacement of GB/T 2423.35-2005 Environmental Testing for
Electric and Electronic Products - Part 2.Test Methods - Test Z/AFc. Combined
Cold/vibration (sinusoidal) Tests for Both Heat-dissipating and Non-heat-dissipating
Specimens; GB/T 2423.36-2005 Environmental Testing for Electric and Electronic
Products - Part 2.Test Methods - Test Z/BFc. Combined Dry Heat/vibration (sinusoidal)
Tests for Both Heat-dissipating and Non-heat-dissipating Specimens; GB/T 2424.22-
1986 Basic Environmental Testing Procedures for Electric and Electronic Products -
Guidance for Combined Temperature (cold and heat) Vibration (sinusoidal) Tests. This
Part integrates the content in GB/T 2423.35-2005, GB/T 2423.36-2005 and GB/T
2424.22-1986.In comparison with these standards, the main technical changes are as
follows.
---The scope of application of tests is extended. combined tests may be conducted
under different vibrational excitations (sinusoidal, random, mixed mode or
shock) and different climatic conditions (cold, dry heat, temperature variation,
cyclic or constant damp heat).
---The previous standard’s specific details of test requirements are not specifically
described in this Part.
This Part adopts translation method and equivalently adopts IEC 60068-2-53.2010
Environmental Testing - Part 2-53.Tests and Guidance - Combined Climatic
(temperature/humidity)] and Dynamic (vibration/shock) Tests.
Chinese documents that have consistent correspondence with the international
documents that are normative references in this Part are as follows.

In order to make it convenient to be used, this Part makes the following editorial
modifications.
---The title of the Standard is modified.
---In Table 1, “√” is used to replace “”.
This Part was proposed by and shall be under the jurisdiction of National Technical
Committee 8 on Environmental Conditions of Electric and Electronic Products and
Environmental Test of Standardization Administration of China (SAC/TC 8).
The drafting organizations of this Part. CEPREI; Shanghai Institute of Quality
Inspection and Technical Research; BEIHANG University.
The main drafters of this Part. Chang Shaoli, Xiehe, Jiangcan, Lu Zhaoming, Wusa.
The issuing of the previous versions of the standard replaced by this Part is as follows.
---GB/T 2423.35-1986, GB/T 2423.35-2005;
---GB/T 2423.36-1986, GB/T 2423.36-2005;
---GB/T 2424.22-1986.
1 Scope
This Part of GB/T 2423 provides a description of test methods and guidance for testing
equipment or components under combined climatic and dynamic conditions.
The purpose of combined testing is to investigate to what extent the equipment or
components are affected by combined climatic and dynamic tests.
2 Normative References
The following documents are indispensable to the application of this document. In
terms of references with a specified date, only versions with a specified date are
applicable to this document. In terms of references without a specified date, the latest
version (including all the modifications) is applicable to this document.
