10.2 Compression testReplacement:10.2.1 Conduits are subjected to a compression test.NOTE: Compression test on fittings is under considerationThe test for conduits containing non-metallic materials is not started until 10 days after manufacture.10.2.2 Samples are (200 ± 5) mm long. 10.2.3 Before the test, the outside and inside diameters of the samples are measured as specified in…

25 Method F5: Water penetration25.1 ObjectThis test applies to continuously water-blocked cables. The purpose is to determine the ability of a cable to block water migration along a specified length. Compliance shall be checked on samples of cable using one of the two following methods (F5A or F5B), as stated in the detail specification. Method…

IEC 60695-2-11 defines the glow-wire flammability test method applied to end-products for fire-hazard assessment. For the purpose of this test method, an end-product includes: The purpose of the glow-wire test is to evaluate whether a part exposed to an abnormal thermal stress: The test is particularly relevant to polymeric and insulating parts used in electrical…

The Cleveland Open Cup (COC) Tester is used to determine the flash point and fire point of petroleum products under controlled laboratory conditions according to ASTM D92. The method is particularly intended for petroleum products with flash points above 79°C (175°F) and below 400°C (752°F), subject to the applicability limitations specified by the standard. What…

How can we evaluate whether polyethylene has been adequately crosslinked? One of the most widely used approaches is to determine its Gel Content and, when required, its Swell Ratio. ASTM D2765 describes test methods for determining the insoluble fraction produced by crosslinking in ethylene plastics. The methods are applicable to crosslinked polyethylene materials of different…

11.1 ObjectThis test method is intended to establish the ability of a fibre optic cable to withstand mechanical twisting. The primary purpose of this procedure is to measure any variation in the optical power transmittance of a fibre when the cable is subjected to torsional forces external to the cable jacket. A secondary purpose is…
