14 Method E10: Kink14.1 ObjectThe purpose of this test is to determine the minimum loop diameter at the onset of the kinking of an optical fibre cable.NOTE Testing has indicated that the results of this test for cable have limited reproducibility. It is advised that it should be used with caution and that any minimum…
🔥 Fire Hazard Testing | 50 W Premixed Flame | Apparatus Requirements | Flame Confirmation | Test Arrangement A standardized flame test is not defined only by flame height. To obtain reproducible fire-test results, the burner geometry, methane purity, gas flow, air supply, flame characteristics, measurement system, test environment and—most importantly—the thermal performance of the…
14 Method E11: Bend14.1 ObjectThe purpose of this test is to determine the ability of an optical fibre cable or cable element to withstand bending around a test mandrel.14.2 SampleThe sample shall be terminated at each end in a manner such that the fibres, sheath(s) and any strain members are clamped together in a representative…
6 Apparatus6.1 Fig. 1 shows an example of the test apparatus that can be used in the performance of this test method. The apparatus requires a pressure vessel rated to a minimum of 690 kPa (100 psi). The vessel diameter should be 600 mm3. Other size vessels may be used but it is up to…
1. Introduction Plastics and polymeric materials exhibit viscoelastic behavior, meaning that their deformation depends not only on the magnitude of the applied stress but also on time, temperature, loading rate, and environmental conditions. For this reason, the results of a conventional short-term tensile, compression, or flexural test cannot by themselves predict how a plastic component…

D.1 GeneralThermal analysis shall be used to characterize the uncured epoxy (powder, one-component liquid ortwo-component liquid) and the cured coating film.Differential scanning calorimetry (DSC) shall be used. Reference can be made to ISO 11357-2 for adescription of the general procedure and definitions. General handling and calibration shall be performed as inISO 11357-2 unless stated otherwise…
4 PrincipleA cylindrical rubber test piece is made to slide over an abrasive sheet of specified abrasive grade at aspecified contact pressure over a given distance. The test piece may be non-rotating or rotating during the test.Abrasion takes place over one of the end surfaces of the cylindrical test piece (see Figure 1). The abrasivesheet…
