3、tober 1997 BSI 09-1999 ISBN 0 580 28554 5 National foreword This British Standard is the English language version of EN 61300-2-4:1997. It is identical with IEC 61300-2-4:1995. The UK participation in its preparation was entrusted by Technical Committee EPL/86, Fibre optics, to Subcommittee EPL/86/2
4、, 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 inter
5、national 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
6、as IEC 60027-1. For a period of time during the change over from one numbering system 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 int
7、ernational publications with their corresponding or 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”
8、facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract.

22、 this part of IEC 1300 is to ensure that the captivation or attachment of the fibre/cable to a fibre optic device will withstand tensile loads likely to be applied during normal service. 1.2 General description The specimen is rigidly clamped to a holding fixture and a tensile load is applied to the
23、 fibre/cable. Potential failure modes for this test include, but are not limited to: a) cable jacket damage; b) fibre breakage or damage; c) cable clamp failure; d) cable pull-out; e) loss of optical continuity; f) degradation of optical transmission characteristics; g) excessive movement of the cab
24、le/terminus relative to the device. 2 Apparatus The apparatus consists of the following elements. 2.1 Holding fixture A means to hold the fibre/cable and the device(s) in position for the duration of the test. The holding, method used shall not distort the device under test. Mount the device in a fi
25、xed position using its normal mounting provisions. As an example, wrap the fibre/cable around a mandrel having a diameter which is at least 25 times the diameter of the fibre/cable. Use an adequate number of turns to preclude slippage. The distance between the rearmost portion of the device under te
26、st and the mandrel tangent point shall be no less than 50 times the diameter of the fibre/cable. NOTEThe fixturing should allow the specimen to be connected to an optical source and detector in order to monitor changes in attenuation (if required by the detail specification). 2.2 Force generator An
27、appropriate device or apparatus capable of smoothly applying the specified force at the specified rate. 2.3 Force gauge An appropriate gauge to register the amount of force being exerted between the device under test and the fibre/cable. This equipment may include a device to record the rate of forc
28、e application or the total time the force is applied, or both. 2.4 Alternative apparatus Unless otherwise specified in the detail specification, other apparatus may be used in lieu of a mechanical separation device or force gauge. For example, the required force may be achieved by applying controlle
29、d increments of mass to one of the holding devices while the other holding device remains fixed. 2.5 Timer A device to measure the total time the force is applied, if the apparatus mentioned in 2.3 is not used. 2.6 Other equipment Optical and other examination and measuring equipment shall be availa
30、ble as required by IEC 1300-3-1 and IEC 1300-3-5, as appropriate. Refer to the required procedure for details. 3 Procedure 3.1 Visually examine each specimen in accordance with IEC 1300-3-1 to ensure that the specimens have not been damaged. 3.2 Unless otherwise specified, precondition each prepared
31、 specimen for 4 h at the standard test conditions specified in IEC 1300-1. 3.3 Securely mount the device under test on the holding fixture and place in the test apparatus. 3.4 Perform any initial optical measurement and make any other measurements as required by the detail specification. Unless othe
32、rwise specified in the detail specification, measure the attenuation in accordance with IEC 1300-3-5. 3.5 Activate the test apparatus so that an axial force is gradually exerted between the fibre/cable and the device under test. Apply the load gradually so as to eliminate any impulse or impact loadi
33、ng effect. If automatic equipment is used, it is recommended that the rate of separation of the holding devices be approximately 25 mm/min. Continue loading until the tensile load specified in the detail specification has been reached. 3.6 Maintain the specified load for the specified time period re
34、quired by the detail specification. While the specimen is under load, make observations and perform measurements as required by the detail specification. 3.7 Remove the test load and perform any final optical measurement required by the detail specification. Unless otherwise specified in the detail
35、specification, measure the attenuation in accordance with IEC 1300-3-5. 3.8 Remove the specimen from the test apparatus and visually examine each specimen in accordance with IEC 1300-3-1.
