According to above table you need below equipment for the target…

J.1 GeneralThis test consists of measuring the reduction of the specific electrical coating resistance after the coating has been conditioned in an electrolyte.J.2 ApparatusThe test is carried out either by bonding and sealing a plastic pipe segment to the surface of the sample or by placing a pipe section horizontally in a plastic container with…

A.1 GeneralThis Annex specifies the test method to verify the leaktightness of the seats and packing of a valve/valve bodies made from PE.A.2 Test pieceThe test piece shall be a complete valve with the open ends closed off by, for example, covers, plugs,flexible seals or end connectors.The setting time of moulded or fusion-jointed components, as…

1 Scope This part of ISO 4589 specifies methods for determining the minimum concentration of oxygen, in admixture with nitrogen, that will support combustion of small vertical test specimens under specified test conditions. The results are defined as oxygen index values. Methods are provided for testing materials that are self-supporting in the form of vertical…

4 Test method4.1 GeneralThis part of IEC 60811 shall be used in conjunction with IEC 60811-100.Unless otherwise specified, tests shall be carried out at room temperature.Two test procedures can be applied to materials, depending on cable system conditions andenvironments; a summary of test conditions is given in Table 1:– for less severe conditions: Method A;–…

4 PrincipleA test specimen is clamped over an expansive diaphragm by means of a circular clamping ring. Increasing fluid pressure is applied to the underside of the diaphragm, causing distension of the diaphragm and the fabric. The volume of fluid is increased at a constant rate per unit time until the test specimen bursts. The…

6.4 Vertical flame 6.4.1 General 6.4.1.1 This test establishes the method for determining the resistance of MPT, fitting, or clamp to the vertical propagation of flame and dropping of flaming particles Specimens shall be separately subjected to two 15-second applications of flame, with 15 seconds between each Raine application 6.4.1.2 Specimens shall be tested in…
