    30、ility of the cord when repeatedly bent. Optical measurements are made before and after the test to screen for 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.

    31、2 Cord A cord is a fibre optic cable terminated with any passive fibre optic connector on both ends, regardless of its expected use. Examples include equipment cords, work area cords or patchcords. BS EN 61300-2-52:2013 6 61300-2-52 IEC:2013 4.3 Specimen The specimen shall be a cord. The connectors

    32、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 61300-3-4 shall be connected to the specimen for monitoring optical performance

    33、 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 of the test mandrel, the number of turns of the mandrel and the number o

    34、f 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 specification. 5.3 Initial examinations and measurements Complete the in

    35、itial 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 sections shall be perpendicular to the mandrel and spacing between the two

    36、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 such that there are no gaps between the cable and the mandrel during the b

    37、ending 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 shall be kept in this position for at least 1 min. f) The specimen shall b

    38、e 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 measurements.

    40、ation, to ensure that there is no permanent damage 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 comb

    41、ination of the number of turns per helix, number of cycles, mandrel diameter and cord length. The severity shall be specified in the relevant specification or taken from Table 1 below: BS EN 61300-2-52:2013 8 61300-2-52 IEC:2013 Table 1 Severity Mandrel diameter 60 mm for cable diameter 4 mm 15 cabl

    43、evant specification: a) cable and connector type; b) wavelength of the attenuation measurement; c) initial examinations and measurements and performance requirements; d) examinations and measurements during test and performance requirements; e) final examinations and measurements and performance req

    44、uirements; f) deviations from test procedure; g) additional pass/fail criteria; h) diameter of the test mandrel, the number of turns of the mandrel, and the number of cycles.
