Edition 2 of HD 21 was implemented on 1 st January 1984, and at that time contained five parts. Since 1984, new parts have been published, original parts amended, and in addition HD
12、505 has superseded HD 385 as the cross-reference for test methods. This edition 3 of HD 21.3 has been introduced to cover the complete revision of the overall dimensions, in line with EN 60719, and was approved by TC 20 at its London meeting in October 1993 to go forward to UAP.
