10 Method E6: Repeated bending10.1 ObjectThe purpose of this test is to determine the ability of an optical fibre cable to withstand repeated bending.Repeated bending of connectorized optical fibre cable involves testing as a unit, testing both the capabilities of the cable and the connector. This testing is defined by IEC 61300-2-44. Refer to that…

5 Apparatus 5.1 Impact surface, which should be either: a) a plane inclined to the vertical at 10° ± 1° (for the inclined plane test), or b) a plane vertical to within 1° (for the horizontal or pendulum test). The dimensions of the impact surface shall be greater than those of the impacting face, or…

12 Method E8: Flexing12.1 ObjectThe purpose of this test is to determine the ability of an optical fibre cable to withstandrepeated flexing in service, e.g. elevator cable.12.2 SampleThe sample shall be terminated at each end in a connector, or in a manner such that the fibres,sheaths and any strain members are clamped together in a…

4 Apparatus 4.1 Falling-weight testing machine, incorporating the following basic components {see figure 1). 4.1.1 Main frame, with guide rails or a guiding tube rigidly fixed in the vertical position, to accommodate a striker (4.1.2) and release it to fall vertically and freely. When calibrated, the speed of the striker at the moment of impact…

(a) Criteria for Acceptance. Each seat cushion must meet the following criteria: (1) At least three sets of seat bottom and seat back cushion specimens must be tested. (2) If the cushion is constructed with a fire blocking material, the fire blocking material must completely enclose the cushion foam core material. (3) Each specimen tested…

10.5 Flexing test10.5.101 An assembly consisting of a conduit with a terminating conduit fitting, assembled in accordance with the manufacturer’s instructions, shall be subjected to a flexing test by means of the apparatus shown in figure 101.10.5.102 The test shall be made on six samples of conduit of an appropriate length. Three of the samples…

First lets take a look at the tests need to be done on the pipe itself according to this norm: 5 General characteristics5.1 AppearanceWhen viewed without magnification the internal and external surfaces of pipes shall be smooth, clean and free from scoring, cavities, and other surface defects to an extent that would prevent conformity to…

3 Equipment—A typical, commercially available machine as used in the preparation of this test procedure and known as a Friction Materials Test Machine is shown in Figures 1 and 2. The Friction Materials Test Machine shall be equipped with suitable means for:a. Measuring the drum temperatureb. Heating the drumc. Controlling the drum heating rated. Cooling…

3 ApparatusOrdinary laboratory apparatus and glassware, together with the following: 3.1 Balance, capable of weighing to an accuracy of 0,1 g. 3.2 Test sieves, circular, with a height of 25 mm to 50 mm and a sieving area approximately 200 mm diameter, made of woven metal wire cloth. The frame of the test sieves shall…

2 PrincipleA test assembly comprising either a fabricated product or an assembly of pipes and/or fittings is subjected to a given internal hydrostatic pressure for a given time period during which the leaktightness of the fabricated product or the joint is verified by inspection.NOTE It is assumed that the following test parameters are set by…
