13、Foreword The text of document 86B/2346/FDIS, future edition 2 of IEC 61300-2-38, prepared by SC 86B, Fibre optic interconnecting devices and passive components, of IEC TC 86, Fibre optics, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 61300-2-38 on 2006-10-01. This

14、 European Standard supersedes EN 61300-2-38:1997. Specific technical changes from EN 61300-2-38:1997 include the specifications of more strict and more detailed sealing properties. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of a

15、n identical national standard or by endorsement (dop) 2007-07-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2009-10-01 Annex ZA has been added by CENELEC. _ Endorsement notice The text of the International Standard IEC 61300-2-38:2006 was approved

18、 This part of IEC 61300 presents a method for testing the sealing performance of a fibre optic closure and sealing system of the closures, when required by the relevant specification. 2 Normative references The following referenced documents are indispensable for the application of this document. Fo

20、eneral description 3.1 Test methods A number of closures are assembled following the manufacturers instructions. The specimens are then sealed, pressurized and tested for leaks by using the pressure gauge (see 3.2.4) and measuring the time to failure. The tests shall be carried out according to the

21、standard test conditions as defined in IEC 61300-1, unless otherwise specified in the relevant specification. Method A is a performance criterion test for leaks when the specimen is pressurized with air and submerged in a water bath. This method is generally used to check the sealing of the closure

22、after installation or after test. Method B is a performance criterion test for leaks when the specimen is pressurized with air and the pressure loss is monitored by using a gauge. This test method is generally used to check the sealing of the closure during mechanical tests at a specified test tempe

23、rature, by measuring the pressure before and after the test. 3.2 Apparatus The apparatus consists of the following elements. 3.2.1 Cable Suitable cable to assemble the specimen shall be used. 5 EN 61300-2-38:2006 3.2.2 Pressurizer A pressurizer provides means of pressurizing the closures. 3.2.3 Capi

24、llary gas connections Suitable capillary gas connections are needed for fitting into the specimen or cable to allow the specimen to be pressurized. 3.2.4 Pressure gauge A pressure gauge is a gauge to measure the pressure inside the closures. Gauges with a suitable range and a resolution of 0,5 kPa t

25、o determine a 5 % drop in pressure shall be used. 3.2.5 Water bath A water bath is needed for method A. 4 Procedure 4.1 Method A Assemble the specimen using the smallest and the largest cable diameter for which the specimen is designed. Install the pressure gauge into the specimen or cable. Seal the

26、 cable ends at their extremities. Pressurize the closure. Submerge the specimen and cable in a water bath just below the water surface at the required temperature. No escape of air bubbles, indicating a leakage, shall be observed during the test. 4.2 Method B Assemble the specimen using the smallest

27、 and the largest cable diameter for which the specimen is designed. Install the pressure gauge into the specimen or cable. Seal the cable ends at their extremities. Pressurize the closure at specified temperature. With the specimen at the test temperature, the air pressure shall be monitored using t

28、he installed gauge. A record of air pressure versus time shall be kept and plotted. The pressure in the specimen shall not decay more than the specified amount. EN 61300-2-38:2006 6 5 Severity The severity is determined by the initial pressure, the time duration for the test and the allowable leakag

29、e or pressure decay during the test. The following preferred severities may be specified for the sealing procedure. The test overpressure for specimens for unpressurized systems is 40 kPa. The test overpressure for specimens for pressurized systems is 98 kPa. 6 Details to be specified The following

30、details, as applicable, shall be specified in the relevant specification: type and diameter of the cable to be used in the test; the procedure for mounting the specimen; duration of test; method of leak detection (Method A or B); allowable leakage for Method A; allowable pressure decay for Method B;

31、 water head (Method A); pre-conditioning of specimens, if any; deviations from test procedure; additional pass/fail criteria. _ Annex ZA (normative) Normative references to international publications with their corresponding European publications The following referenced documents are indispensable
