It is identical with IEC 61300-2-35:1995. 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 responsibility 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 organizations represented on this subcommittee can be obtained on request to its secretary. From 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered as IEC 60027-1. For a period of time during the change over from one numbering to the other, publications may contain identifiers from both systems. 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. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, the EN title page, pages 2 to 4 and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.

CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CENELEC member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the same status as the official versions.

During the rotation a tensile force is applied to the cable. 2 Apparatus An example of the test apparatus is given in Figure 1. This test apparatus consists of the following elements. 2.1 Clamping device A suitable clamping device able to describe a circle without transmitting axial rotation to the specimen (the line XX remains vertical). 2.2 Pulley A swivel pulley. 2.3 Force generator A force generator capable of smoothly applying the required tensile force to the cable end.

The severity shall be specified in the detail specification. The following preferred severities are non-mandatory severities which may be specified for this procedure: 5 Details to be specified The following details, as applicable, shall be specified in the detail specification: Cable type Mounting procedure Number of cycles Tensile load Specimen optically functioning or non-functioning Specimen mated or unmated Pre-conditioning procedure Recovery procedure Initial examinations and measurements and performance requirements Examinations and measurements during test and performance requirements Final examinations and measurements and performance requirements Deviations from test procedure Additional pass/fail criteria Tensile force N Number of cycles 10 20 30 40 80 100 150 200 10 50 100 500 1 000 5 000 10 000 Licensed Copy: sheffieldun sheffieldun, na, Sat Nov 11 12:56:28 GMT+00:00 2006, Uncontrolled Copy, (c) BSI blank Licensed Copy: sheffieldun sheffieldun, na, Sat Nov 11 12:56:28 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS EN 61300-2-35: 1997 IEC 61300-2-35: 1995 BSI 389 Chiswick High Road London W4 4AL BSI British Standards Institution BSI is the independent national body responsible for preparing British Standards.
