3、dard is the English language version of EN61300-3-11:1997. It is identical with IEC61300-3-11:1995. The UK participation in its preparation was entrusted by Technical Committee EPL/86, Fibre optics, to Subcommittee EPL/86/2, Interconnecting devices and passive components, which has the responsibilit
4、y to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of o
5、rganizations represented on this subcommittee can be obtained on request to its secretary. From1January1997, all IEC publications have the number60000 added to the old number. For instance, IEC27-1 has been renumbered as IEC60027-1. For a period of time during the change over from one numbering syst

Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications.

21、nnector set. 1.2 General description The connector set components are mounted so that a controlled coupling force or torque can be applied. The force or torque is measured during the entire coupling and/or uncoupling cycle. The procedure is applicable to either twist or push-pull type coupling mecha
22、nisms. 2 Apparatus The apparatus shall consist of the following elements. 2.1 Holding fixture(s) The holding fixtures shall be capable of holding the mating components so that they do not influence the measured force or torque value. Proper alignment of the mating components shall be maintained thro

Unless otherwise speci
25、fied, the mating time shall be3s minimum. 3.5 Apply and measure the force or torque to unmate the connector set.
