It is identical with IEC 61300-2-34:1995. The UK participation in its preparation was entrusted by Technical Committee EPL/86, Fi
4、bre 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 inter
5、ests 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 ins
6、tance, IEC 27-1 has been renumbered 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 whi

The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondenc

23、pe and object The purpose of this part of IEC 1300 is to establish the ability of a fibre optic device to resist degradation when exposed to specific solvents or contaminating fluids with which the component may come into contact during its service life. 1.2 General description The specimen is immer
24、sed in the fluid for a specified period of time. A separate specimen shall be used with each fluid. WARNING Intended users of this procedure are cautioned that tests of this nature may involve the use of certain hazardous materials, operations and equipment. In particular, some of the fluids that ma
25、y be used are flammable or may constitute health hazards, or both. Test temperatures should be at least 10 C below the flashpoint of any fluid being used. Open flame heat sources should not be used with any organic solvents. Test personnel should consult the relevant materials safety data sheets whe
26、n necessary. 2 Apparatus The apparatus consists of the following elements. 2.1 Containers A boro-silicate glass or stainless steel vessel of suitable volume for each test fluid shall be used. Vessels shall be of sufficient size and capacity to permit the specimen to be appropriately immersed in the
27、selected fluid without violating other physical constraints (e.g. minimum cable bend radius). 2.2 Fluids Prepared immersion fluids. 2.3 Heat source A suitable heat source capable of achieving and maintaining the specified temperatures within 2 C of the required setting. 2.4 Oven A suitable oven to d
28、ry the specimen. 3 Procedure The preparation of the specimen shall be in accordance with the detail specification. Unless otherwise specified, the specimen shall be subjected to the test in a non-operational mode. 3.1 Pre-condition the specimen and the fluid as specified in the detail specification.
29、 3.2 For each specified fluid, prepare a vessel with sufficient fluid such that the specimen can be adequately immersed. 3.3 Immerse the specimen for 18 h while maintaining the fluid temperature. NOTEIn the case of volatile fluids, it may be necessary to add addtional amounts of fluid (heated to the
30、 test temperature) during the test in order to keep the specimen immersed. 3.4 At the end of the 18 h period, remove the specimen and wipe off surplus fluid. 3.5 Place the specimen in an oven and dry for 2 h at 70 C. 3.6 Upon completion of the test, the specimen(s) shall be examined and all necessar
31、y observations recorded as specified in the detail specification. Careful attention shall be given to swelling of materials, loss of adhesive bonding between bonded surfaces, corrosion of materials, softening of materials, degradation of optical characteristics, etc. Licensed Copy: sheffieldun sheff
