Two test schedules are provided. The qualification test sche

27、dule applies to insulation piercing connections which conform to all requirements of clause4. These requirements are derived from experience with successful applications of such insulation piercing connections. The application test schedule applies to insulation piercing connections which are part o

28、f a component and are already qualified. 1 Scope and object This part of IEC60352 is applicable to insulation piercing connections made with stranded wires and tinsel-wire, flat conductors and flat flexible circuitries for use in telecommunication equipment and in electronic devices employing simila

29、r techniques. Information on materials and data from industrial experience is included in addition to the test procedures to provide electrically stable connections under prescribed environmental conditions. The object of this standard is to determine the suitability of insulation piercing connectio

30、ns under specified mechanical, electrical, and atmospheric conditions; provide a means of comparing test results, when the tools used to make the connections are of different designs or manufacture. There are different designs and materials for insulation piercing terminations in use. For this reaso

31、n only fundamental parameters of the termination, the performance requirements of the conductor and the complete connection are specified in this standard. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this
