Standards and Publications are adopted by ECIA in accordance with the American National Standards Institute (ANSI) patent policy. By such action, ECIA does not assume any liability to any patent owner, no
5、r does it assume any obligation whatever to parties adopting the Standard or Publication. This standard is based upon the major technical content of International Electrotechnical Commission standard 512-8, test 16m, unwrapping, solderless wrapped connections, 1993-01, third edition. It conforms in
6、all essential respects to this IEC standard. This Standard does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of this Standard to establish appropriate safety and health practices and to determine th
7、e applicability of regulatory limitations before its use.
