International Standard IEC 60115-1 has been prepared by IEC technical committee 40: Capacitors and resistors for electronic equipment This fourth edition cancels and replaces the third edition issued in 199

18、9 and Amendment 1 (2001). It constitutes a technical revision. This standard cancels and replaces IEC 61045-1 (1991), IEC 61045-2 (1991) and IEC 61045-2-1 (1991). This edition contains the following significant technical changes with respect to the previous edition: a) implementation of Annex Q whic

19、h replaces Clause 3; b) addition of new tests procedures in 4.34 through 4.38; c) removal of the property “temperature characteristics“ from 4.8; EIA-60115-1 Page 2 d) introduction of a new system of test severities for the shear test in 4.32; e) introduction of new bias voltages for the damp heat s

This bilingual version (2013-07) corresponds to the monolingual English version, published in 2008-07. The

21、 text of this standard is based on the following documents: FDIS Report on voting 40/1907/FDIS 40/1922/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. The French version of this standard has not been voted upon.
