23、54833 bOT Page 4 EN 60352-3 : 1994 INTRODUCTION Two standards are available on solderless insulation displacement connections: Part 3: Solderless accessible insulation displacement connections - General require- ments, test methods and practical guidance; Pari 4: Solderless non-accessible insulation
24、 displacement connections - General requirements, test methods and practical guidance. This standard includes requirements, tests and practical guidance information. Two test schedules are provided: - The Basic Test Schedule applies to insulation displacement connections which conform to all require
25、ments of section 2. These requirements are derived from experience with successful applications of such connections. - The Full Test Schedule applies to insulation displacement connections which do not fully conform to all requirements of section 2, for example those which are manu- factured using m
26、aterials or surface finishes not included in section 2. This philosophy permits cost and time effective performance verification using a limited Basic Test Schedule for established connections and an expanded Full Test Schedule for connections requiring more extensive performance validation. NOTE -
27、In this standard the term insulation displacement“ is abbreviated to *ID., for example ID connec- tion“ , “ID termination“.

29、ible for tests and measurements according to section 3 and which are made with: - appropriately designed ID terminations; - wires having solid round conductors of 0,25 mm to 3,6 mm nominal diameter; - wires having stranded conductors of 0,05 mm2 to 1 O mm2 cross-section; for use in telecommunication
30、 equipment and in electronic devices employing similar 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. 2 Object To determine the suitability o
31、f accessible ID connections under specified mechanical, electrical and atmospheric conditions. There are different designs and materials for ID terminations in use. For this reason only fundamental parameters of the termination are specified while the performance require- ments of the wire and the c
32、omplete connection are specified in full detail. To provide a means of comparing test results when the tools used to make the connec- tions are of different designs or manufacture. 3 Normative references The following normative documents contain provisions which, through reference in this text, cons
