It is identical with IEC 61300-2-23:1995. The UK participation in its preparation was entrusted by Technical Committee
4、 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; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep t
5、he UK interests 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 numb
6、er. For instance, 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 a
7、n annex which lists normative references to international publications with their corresponding 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 Co
8、rrespondence 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 of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does
9、 not of itself confer immunity from legal obligations.

24、cting the fibre optic device to immersion in water. 1.2 General description This procedure is conducted in accordance with IEC 68-2-17. Three methods are described in the test procedure. Method 1 is conducted in accordance with IEC 68-2-17, test Qa. The specimen is mounted on the lid of a pressurize
25、d test chamber which is submerged in a liquid. If the specimen leaks, the air escaping is collected. The amount of air collected per unit time is a measure of the air leakage. Method 1 contains two test types. Type A applies the pressure in the direction specified in the detail specification. Type B
26、 applies the pressure in both directions. Method 2 is conducted in accordance with IEC 68-2-17, test Qf. The specimen is immersed either in a water tank at a specified depth or in a pressure water chamber to achieve the specified pressure head. Method 3 is conducted in accordance with IEC 68-2-17, t
27、est Qk. This procedure contains two test types. Type A consists of impregnating the specimen with helium under pressure. The leak rate of the specimen is then measured under vacuum with a mass spectrometer and the equivalent standard leak rate deduced. This method is only applicable to specimens whi
28、ch do not contain gas retention surfaces such as joints or organic materials as they may impair the results. Type B is similar to Type A except that the impregnation phase is omitted. It is intended for specimens that were filled during manufacture with a mixture containing a large portion of helium
29、. This method is not suitable for general hermetic testing such as that required at the end of environmental tests. 1.3 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this part of IEC 1300.
