Foreword
GB/T 2421 is currently divided into the following sections.
--- GB/T 2421.1 electric and electronic products environmental testing overview and guidance;
--- GB/T 2421.2 electric and electronic products environmental testing specifications prepared by using test summary information.
This part of GB/T 2421 Part 2.
This section identical with IEC 60068-4. 1987 "Basic environmental testing procedures - Part 4. Test Specification compilers with information Overview
To "(in English) and its amendments 1.1992 and Amendment 2.1994.
For ease of use, this part of IEC 60068-4. 1987 to do only the following editorial changes.
--- To be consistent with the new IEC 60068 title name, the title of this section by the name of "Basic environmental testing procedures" to "electrical and electronic
Environmental testing ";
--- "IEC 60068-4. 1987 This Part" was changed to "GB/T 2421.2-2008 this section";
--- Remove the IEC 60068-4. 1987 Foreword and Preface;
--- Increase the national standard foreword;
--- Increasing the normative references, there is a reference to the correspondence between the national standards with international standards;
--- Increasing the figure caption and table title, and in accordance with the order number;
--- Increase the informative appendix NA "national standard" electric and electronic products environmental testing "component."
This part of all test methods are consistent with the IEC standard description latest national standards, unless the new national standard and IEC standard
Original inconsistent, consistent with the use of legacy national standards. Such as GB/T 2423.38 test R, and the 2008 version of the standard
IEC 60068-4. 1987 there is a big difference, so this part is still using the 1990 version of the standard.

Environmental testing for electric and electronic products
Summary information by using standardized test preparation
Objective 1
When the need to provide a complete standards for the preparation of specifications and other personnel GB/T 2423 in the summary of each environmental test.
Test personnel should be noted that the test can not completely replace the standard outline.
2 Overview
In GB/T 2421.1 can be found in the main content GB/T 2423 each involving environmental testing standards, including the definition and guidelines.
The standard test methods used to explain, to distinguish between different tests.
Summary omitted tolerance, tolerance in GB/T 2423 series of standards.
2.1, 2.2 and 2.3 of the information applies to the main outline, does not apply to all profiles.
2.1 Guidelines
GB/T 2423 standard contains a number of test procedures for application guidelines, many guidelines for the preparation of specifications and other details do not need to understand
Human trials particularly valuable. For these criteria, a summary will not be specifically mentioned guidelines.
There are other cases, the test guidelines in other standards GB/T 2423's, or GB/T 2424 series of standards described in the letter as background
Interest, such as solar radiation test (GB/T 2423.24) guidelines in GB/T 2424.14 in. Under these circumstances, in order to fully regulate
Test showed that the required details of the source, regardless of the degree of correlation reference standards and norms compilers, and will point out the relevant reference summary
standard. Such standards are listed in Chapter 5.
2.2 Storage
GB/T 2424.19 gives the GB/T 2423 series of standards in the short to simulate the impact of long-term storage test guidelines, where applicable
You should refer to the guidelines.
2.3 Installation
GB/T 2423.43 purpose is to shock (GB/T 2423.5Ea) in the outline mentioned collision (GB/T 2423.6Eb), positive
Chords and random vibration (GB/T 2423.10Fc and GB/T 2423.11Fd, GB/T 2423.12Fda, GB/T 2423.13Fdb,
GB/T 2423.14Fdc) and steady-state acceleration (GB/T 2423.15Ga) and other test samples to be tested in the proposed installation requirements, the relevant norms
We should pay attention to these requirements. Of course, these requirements also apply the provisions of Chapter 3 of "comprehensive" or "combined" test (including one or more test
Test).
3 Terms and Definitions
