2、roduction or networking permitted without license from IHS-,-,-National forewordThis British Standard is the UK implementation of EN 61300-2-52:2013. It isidentical to IEC 61300-2-52:2013.BSI, as a member of CEN, is obliged to publish EN 61300-2-52 as a BritishStandard. However, attention is drawn t
3、o the fact that during the development of this European Standard, the UK committee voted againstits approval as a European Standard. The committee noted a possible inconsistency between clause 3, whichstates that optical measurements should be made before and after thetest, and clause 5.4, c) which
4、states that optical measurements are alsomade during the test. The committee is also of the opinion that the mention of fibre, cable and resilient members being fixed together inclause 4.3 may not be appropriate for all fibre optic connectors.The UK participation in its preparation was entrusted by
5、TechnicalCommittee GEL/86, Fibre optics, to Subcommittee GEL/86/2, Fibre opticinterconnecting devices and passive components.A list of organizations represented on this subcommittee can be obtained on request to its secretary.This publication does not purport to include all the necessary provisions

Optical measurements are made before and after the test to screen for
34、 evidence of damage to the fibre/cable. 4 Apparatus 4.1 General A single mandrel apparatus shall enable the sample to be wrapped tangentially in a close helix around a single test mandrel. 4.2 Cord A cord is a fibre optic cable terminated with any passive fibre optic connector on both ends, regardle
35、ss of its expected use. Examples include equipment cords, work area cords or patchcords.

36、-2-52 IEC:2013 4.3 Specimen The specimen shall be a cord. The connectors shall be terminated according to the manufacturers instructions so that the fibre, cable and resilient members are fixed together. 4.4 Optical measurements Unless otherwise specified, measuring equipment specified in IEC 61300-
37、3-4 shall be connected to the specimen for monitoring optical performance during the test. 5 Procedure 5.1 General Sufficient tension shall be applied to ensure that the sample contours the mandrel. The sample shall then be unwrapped. A cycle consists of one wrapping and one unwrapping. The diameter
38、 of the test mandrel, the number of turns of the mandrel and the number of cycles shall be shown in the relevant specification. 5.2 Preconditioning Precondition the specimen and all equipment for 2 h under standard test conditions as defined in IEC 61300-1, unless otherwise specified in the relevant
39、 specification. 5.3 Initial examinations and measurements Complete the initial examinations and measurements. 5.4 Procedure a) Connect the specimen to the optical measurement equipment according to IEC 61300-3-3. b) The specimen shall be initially positioned as shown in Figure 1. The two straight se
40、ctions shall be perpendicular to the mandrel and spacing between the two straight sections shall be such that the diameter of the loop is greater than the cables minimum bend diameter. c) Start the optical power measurements. d) The specimen shall be wrapped around the mandrel at a uniform tension s
41、uch that there are no gaps between the cable and the mandrel during the bending cycles (see Figure 2). The required number of turns around the mandrel shall be applied. Each revolution of cable on the mandrel shall be close to the adjacent revolutions or cable wraps (see Figure 3). e) The specimen s
42、hall be kept in this position for at least 1 min. f) The specimen shall be unwrapped and kept in this position for at least 1 min. g) The required number of cycles shall be applied by repeating steps d) to f) in a timely manner at a rate no greater than 1 wrap per minute. h) Stop optical power measu

45、amage to the specimen. The results of the final measurement shall be within the limit established in the relevant specification. Visually check (IEC 61300-3-1) that the cable and fibre optic device are not damaged. 6 Severity Severity consists of the combination of the number of turns per helix, num
46、ber of cycles, mandrel diameter and cord length.
