Table 9 shows test items from this standard. Table 9 JASO D001 General rules of environmental testing methods for automotive electronic equipments Method No. Title 5.1 Normal power supply voltage test 5.2 Test for power supply voltage upon engine starting 5.3 Power source micro interruption test 5.4 Power supply inverse polarity connection test 5.5 Overvoltage test (A method) 5.6 Overvoltage test (B method) 5.7 Transient voltage characteristics test 5.8 Electrostatic test 5.9 Conducted electromagnetic test 5.10 Radiated electromagnetic test 5.11 Temperature characteristic test 5.12 Low temperature maintain test 5.13 Low temperature operation test 5.14 High temperature maintain test 5.15 High temperature operation test 5.16 Heat cycle test 5.17 Thermal shock test 5.18 Temperature and humidity cycle test 5.19 Constant high humidity test 5.20 Dew formation test 5.21 Water resistance test 5.22 Salt water spray test 5.23 Vibration test 5.24 Shock resistance test 5.25 Dust resistance test 5.26 Oil resistance test * An English version of JASO D001 has been issued.

5-4-2 EIAJ (Electronic Industries Association of Japan, currently Japan Electronics and Information Technology Industries Association) The creation of the Japan Electronics and Information Technology Industries Association (JEITA) in November 2000 resulted from a merger of the Japan Electronic Industry Development Association and the Electronic Industries Association of Japan. Existing standards from the old organizations were transferred unchanged to the new organization. In other words, standards from the Electronic Industries Association of Japan, known as “EIAJ standards,” continue to exist and are still called “EIAJ standards.” Standards are issued for each individual environmental test. Table 10 presents some examples of EIAJ environmental testing standards. Table 10 EIAJ standards for environmental test methods No. Title CP-5102 Methods of measurement on receiving antennas for SHF satellite broadcast transmission (mechanical and environmental characteristics) ED-2531 Environmental test methods for Liquid Crystal Display devices ED-4701* Environmental and endurance test methods for semiconductor devices ED-8403 Environmental and endurance test methods for semiconductor pressure sensors (diffused piezoresistance type) ED-8503 Environmental and endurance test methods for mini-mold type hall sensors ET-7407* Environmental and endurance test methods for CSP/BGA package on mounting condition RC-8325 Testing methods for environmental test of audio magnetic heads * English versions have been issued for standards marked with an asterisk. 5-4-3 JTM (Testing Machinery Association of Japan) The standards issued by the Testing Machinery Association of Japan differ from those we have been discussing up to this point. Rather than addressing environmental test methods, these standards are set for the test equipment. Tabai is a member of this association, and participates in issuing the standards. Table 11 presents some examples of JTM standards. No. Title JTM K-01:1998 Humidity chambers—Test and indication method for performance JTM K-02-1999 Standard for safety of humidity chambers JTM K-03-1992 Standard for performance of environmental temperature and humidity rooms JTM K-04:1992 Standard for safety of environmental temperature and humidity rooms JTM K-05:2000 High temperature chambers—Test and indication method for performance JTM K-06: 2001 Standard for safety of high temperature chambers 6. Supplement Table 11 JTM standard This report has presented a brief overview of environmental testing standards to provide an aid to understanding the basics of those standards. While the examples given are typical, they cannot provide a thorough treatment of the subject. Please realize also that the test methods presented in the tables cannot cover every aspect. As has been noted, obtaining information about standards requires knowledge of trends in test technology, and so one must be vigilant in keeping up with the latest trends.
