F.1 GeneralThe test consists of assessing the resistance to disbondment of damage to the FJC when exposed to cathodic polarization.The test shall be performed on a test sample taken from the coated components previously subjected toholiday detection (see Annex B), and in which an artificial defect of a defined size has been drilled. The test…
5 Method C — Manometric method5.1 PrincipleA test portion is heated to a specified temperature in a closed container under vacuum, thus ensuringcomplete evaporation of the water. The resulting pressure increase, which is proportional to the water content, is measured. The water content in the sample is calculated using a calibration factor. The calibration factor…
9 General requirements for pipes9.1 AppearanceWhen viewed without magnification, the internal and external surfaces of the pipe shall be smooth, clean and free from scoring, cavities and other surface defects which would prevent conformity with this International Standard. The material shall not contain visible impurities. The ends of the pipe shall be cut cleanly and…
Testing according to EN 12201-3 for Water Fittings 7.3 Requirements when tested in accordance with the test methods as specified in Table 4 using the parameters given in Table 4G the fitting shall have mechanical characteristics conforming to the requirements given in Table 4. 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…
6 Method E2: Abrasion6.1 Method E2A: Abrasion resistance of optical fibre cable sheaths6.1.1 ObjectThe abrasion resistance of optical fibre cables has two aspects:a) the ability of the sheath to resist abrasion;b) the ability of cable markings to resist abrasion.The purpose of this test is to determine the ability of an optical fibre cable sheath to…
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…
