Foreword
GB/T 2423 Environmental Testing for Electric and Electronic Products - Part 2: Test
Methods is divided into several parts in accordance with the test methods.
This is Part 32 of GB/T 2423. This Part equivalently adopts international standard IEC
60068-2-54:2006. In comparison with the international standard, this Part mainly
makes the following editorial modifications:
a) The Foreword and Introduction of the international standard are deleted;
b) The Foreword of the national standard is added;
c) The national standards that adopt international standards are quoted;
d) The tabs A.1 ~ A.11 in Appendix A are deleted, and the contents are directly
converted into paragraphs.
In comparison with the previous version, the main differences are as follows:
a) This Part combines GB/T 2423.32-1985 and GB/T 2424.21-1985;
b) Lead-free solder is added;
c) Different test temperatures are set in accordance with the solder composition;
d) The polarity of force of the force-time curve;
e) Representative points and parameters on the force-time curve;
f) GB/T 2424.21-1985 is modified into Appendix B;
g) Bibliography is added.
Appendix A of this Part is normative; Appendix B is informative.
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 organization of this Part: Guangzhou National Electric Apparatus
Research Institute.
The main drafter of this Part: Yan Jinglian.
The issuing of the previous versions:
---GB/T 2423.32-1985;
Environmental Testing for Electric and Electronic
Products - Part 2: Test Methods - Test Ta: Solderability
Test by the Wetting Balance Method
1 Scope
This Part of GB/T 2423 outlines Test Ta, solder bath wetting balance method applicable
for any shape of component terminations to determine the solderability. It is especially
suitable for reference testing and for components that cannot be quantitatively tested
by other methods. For surface mounting devices (SMD), IEC 60068-2-69 should be
applied if it is suitable.
