6.3.4.12 Watertightness a) A 1.5 m length of completed cable with its ends unsealed shall be installed through a gland in a testtank with approximately 150 mm of the cable protruding into the tank. The gland to be used for this test shall be of the type fitted in submarine pressure–tight bulkheads as shown on…

8.1 Test Criteria8.1.1 Materials shall be classified V-0, V-1, or V-2 on the basis of results obtained on small bar specimenswhen tested as described in (8.2.1 – 8.5.6).8.1.2 Some materials, due to their thinness, distort, shrink, or are consumed up to the holding clampwhen subjected to this test. These materials may be tested in accordance…

2 PrincipleA piece of PVC-U pipe, of specified length, chamfered at one end to an angle dependent on its thickness, is immersed for (30 ± 1) min in dichloromethane, at a temperature T specified by the referring standard, to verify that the PVC-U is not attacked at that temperature. For safety reasons, the surface area…

3 PrincipleThe scattered and unscattered light energy of a wavelength of 540 nm to 560 nm passing through a test piece cut from a pipe or fitting is measured and expressed as a percentage of the incident light energy on the test piece. 4 Apparatus4.1 Photoelectric cell, used such that the response of the reading…

4 Apparatus4.1 DSC instrument, and associated software, calibrated.Calibration should be carried out using at least two different metals. An instrumental baseline must be obtained with an empty sample pan and reference pan in place, and with temperature settings and purge gas identical to the settings to be used for the sample analysis.4.2 Aluminium sample pans.4.3…

4 Apparatus4.1 Apparatus for procedure A4.1.1 A suitable apparatus for procedure A is shown in Figure 1. 4.1.2 Enclosed tank, capable of being used at the appropriate test pressure and receiving the testspecimen. The ends of the test specimen shall pass through the walls of the tank, so that the inside of thepipe is open…
