Reason for withdrawal of JASO Standard
1. Applicable standard
JASO D 001:1994 General rules of environmental testing methods for automotive electronic equipment
2. Background to withdrawal of standard
This standard was proposed based on the results of an investigation by the Electronics Research Committee of
the Technology Board of the Society of Automotive Engineers of Japan, Inc. It was established in 1978 ahead ofa related standard issued by the International Organization for Standardization (ISO). Its contents were revisedand fully updated in 1982, 1987, and 1994, and it was valued as an extremely effective standard by automakers
and electronic equipment manufacturers due to its description of durability test methods under generalenvironments, including electromagnetic, as well as temperature, humidity and vibration conditions.
Then, starting in around 1983, ISO/TC22/SC3/WG3 began work to establish standards describing
electromagnetic environment test methods for vehicles and automotive components. Despite Japan strongly
urging the adoption of JASO D 001, a majority agreed to pursue the proposals made by Europe and the U.S.,
which resulted in the establishment of series of basic standards from the second half of the 1990s. Work torevise these standards and add new hardware remains ongoing to this day.
During the previous revision of this JASO standard in 1994, the committee studied whether to include it in thegeneral policy of harmonization with international standards. However, since most of the related standards at
the time were only Committee Drafts (CD) or Draft International Standards (DIS), it was decided to create JASO
standards with reference to these related standards once the ISO standards had been finalized. For this reason,
the committee decided to consider continuing or withdrawing JASO D 001 at each periodic revision timing,
considering the progress of these JASO standards.
In addition, the ISO 16750 series related to general environmental testing under other than electromagnetic
conditions was also established in 1998. In response to this and the situation in Japan, the JASO D 014 series
was established in 2006. This completed preparation to switch over to methods in harmony with international
standards in the same way as the electromagnetic environmental testing methods.
