20、 or attachment of a cable to a fibre optic device will withstand a flexing in one plane motion under tensile load of the sort likely to be applied during normal use. This test can be applied to single fibre cables and multiple fibre cables 2 Normative references The following referenced documents ar

24、3 General description The device under test is rotated 90o about an axis perpendicular to the axis of the attached cable and in the case of ribbon cable, parallel to the width of the ribbon. This causes a flexing of the strain relief and cable close to the device under test. During the flexing, a te
25、nsile force, but no torque, is applied. If the cable contains ribbon fibre, the flexing motion is applied only across the width of the ribbon.

Visually check (IEC 61300-3-
32、1) that the attachment of the cable to the fibre optic device is not damaged. 5.2 Preconditioning Pre-condition the specimen and all equipment for 2 h at the standard test conditions as defined in IEC 61300-1, unless otherwise specified in the relevant specification. 5.3 Initial measurements Complet
33、e initial examinations and measurements on the specimen as required by the relevant specification. Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 13 04:32:27 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 6 5.4 Conditioning Install the device under test on the apparatus. Measure the attenuation (IE
34、C 61300-3-4) of the device under test with the flexing arm in a vertical position. Apply the specified tensile load and apply specified number of flexes. Use gentle rotational movements, not exceeding 20 cycles/min. The dwell at each extreme shall not be greater than 5 s. Measure the change in atten
35、uation (IEC 61300-3-3) during test. Stop the flexing with the flexing arm in vertical position. Remove the tensile force. 5.5 Recovery Allow the specimen to remain under standard test conditions for 2 h, as defined in IEC 61300-1, unless otherwise specified in the relevant specification. Clean the s
36、pecimen in accordance with the manufacturers instructions. 5.6 Final measurements Remove the device from the apparatus and make final measurements, as defined by the relevant specification, to ensure that there is no permanent damage to the specimen. The results of the final measurement shall be wit
37、hin the limit established in the relevant specification. Visually check (IEC 61300-3-1) that the attachment of the cable to the fibre optic device is not damaged. 6 Severity Severity is specified by the magnitude of tensile force and the number of cycles to the right and left. Recommended values of
