3、1300-2-30:1997. It is identical with IEC61300-2-30:1995. The UK participation in its preparation was entrusted by Technical Committee EPL/86, Fibre optics, to Subcommittee EPL/86/2, Interconnecting devices and passive components, which has the responsibility to: aid enquirers to understand the text;
4、 present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommitt
5、ee can be obtained on request to its secretary. From1 January1997, all IEC publications have the number60000 added to the old number. For instance, IEC27-1 has been renumbered as IEC60027-1. For a period of time during the change over from one numbering system to the other, publications may contain
6、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 international publications with their corresponding European publications. The British Standards which implement these internati
7、onal or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions
8、of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

21、adiation on the materials of a fibre optic device. It is intended to simulate the radiation experienced at the surface of the earth. 1.2 General description This procedure is conducted in accordance with IEC68-2-5, test Sa. The specimen is subjected to an irradiance of1,120kW/m 2with a prescribed sp
22、ectral distribution. The test includes three methods differing in the irradiation cycle times. WARNING NOTEIntended users of solar radiation tests are cautioned regarding the health hazards associated with tests of this nature. IEC68-2-9, clause9 deals with this subject. 1.3 Normative references The
23、 following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC1300. At the time of publication, the edition indicated was valid. All normative documents are subject to revision, and parties to agreements based on this part of IEC130
24、0 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.
