GB/T 2423.2-2008 Test B Standard Introduction
GB/T 2423.2-2008 Test B is a test standard for "Environmental testing for electrical and electronic products Part 2: Test methods Test B: High temperature" and will be implemented on October 1, 2009

GB/T 2423.2 is Part 2 of the GB/T 2423 standard. The components of the GB/T 2423 standard are shown in the informative appendix NA.

This part is equivalent to IEC 60068-2-2:2007 "Environmental testing Part 2-2: Test B: Dry heat" (English version).

Compared with IEC 60068-2-2:2007, this part has made the following editorial changes:

The name of this part has been changed to: "Environmental testing for electric and electronic products Part 2: Test methods Test B: High temperature";

The term "this standard" has been changed to "this part";

-- The foreword of IEC 60068-2-2:2007 has been deleted;

-- The introduction of IEC 60068-2-2:2007 has been deleted, and its content has been converted into the content of the added informative appendix NB;

-- The informative appendix "Components of GB/T 2423 standard" (see Appendix NA) has been added;

-- The informative appendix "Relationship between the lowercase letters of the classification codes of Test A: Low temperature and Test B: High temperature" (see Appendix NB) has been added:

-- "For non-heat dissipation test samples," in the first paragraph of Chapter 1 has been deleted;

-- The list of normative references in Chapter 2 has added GB/T 2423. 22;

——4.3 title "Comparison of application of temperature sudden change and temperature gradual change test" is changed to "temperature gradual change test";

——6.8.2 title "absolute humidity" is changed to "humidity".

For the sake of clarity, the above changes have been added to the corresponding position of the text.

This part replaces GB/T 2423. 2-2001 "Environmental testing for electrical and electronic products Part 2: Test method Test B: High temperature". Compared with it, the main changes are as follows:

——Deleted Test Ba: High temperature test of temperature sudden change of non-heat dissipation test sample;

——Deleted Appendix A, Appendix B, Appendix C, Appendix D, Appendix E, Appendix F;

——Added Test Bc: High temperature test of temperature gradual change of heat dissipation test sample. The test sample is powered on during the entire test process.
