1.SCOPE
These standards provide for environmental test methods and endurance test methods (especially life tests) aimed at evaluating the resistance and the endurance of discrete semiconductor devices and integrated circuits (hereinafter generically called semiconductor devices) used in electronic equipment mainly for general industrial applications and consumer applications, under the various environmental conditions of various kinds that occur during their use, storage and transportation.
2.DEFINITION OF TERMS
The definitions of the technical terms used in these standards and in the relevant specifications are given in EIAJ ED-4701/001 "Environmental and endurance test methods for semiconductor devices (General)."
3.PRECAUTIONS
The precautions used in these standards and in the relevant specifications are given in EIAJ ED-4701/001 "Environmental and endurance test methods for semiconductor devices (General)."
4.TEST METHODS
Refer to the Appendix for the test methods.
Remarks:
The various test methods are arranged independently for the sake of more convenient use of these standards.
COMMENTS
1.PURPOSE OF ESTABLISHMENT OF THESE STANDARDS
Before the establishment of these standards, the standardization referring to EIAJ ED-4701 "Environmental and endurance test methods for semiconductor devices" established on Feb., 1992, and EIAJ has issued amendments, whenever the revision and also new test method establish.
However, it is recondite where the latest test methods are entered, it was resulting the confusion of users. So establishment of new numbering system that is easy to use both users and manufacturers was decided, and reached to the issuance in this time.
Electronic Industries Association of Japan (EIAJ) and The Japan Electronic Industry Development Ass
ociation (JEIDA) have merged effective November 1,2000, the Japan Electronics and Information Technology Industries Association (JEITA).
2.EVOLUTION OF THE DELIBERATIONS
The revision of the standards and new numbering system have been deliberated by "Sub-Committee on Semiconductor Devices Reliability" of the Technical Standardization Committee on Semiconductor Devices/Semiconductor Devices Reliability Group from Apr., 2000. Though to issue as a separate standard every each test method was considered, it made to issue with the system like the following.

(General)
(b)EIAJ ED-4701/100Environmental and endurance test methods for semiconductor devices
