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…
5 Apparatus5.1 Electric Furnace, at least 20 cm (7.9 in.) long suitable for use with the tubing described in 5.2.5.2 High Temperature Glass Combustion Tube, 4 of appropriate diameter and approximately twice as long as the furnace described in 5.1.5.3 Stoppers—Two rubber or neoprene stoppers, to fit the tube described in 5.2, unless the tube…
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…
6 Apparatus 6.1 Thickness Testing Instrument —The thickness gauge shall have a base (or anvil) and a free moving presser foot plate whose planar faces are parallel to each other to <0.01 mm. A gauge with a 56.4 mm (2.22 in.) diameter presser foot, the base shall extend at least 10 mm in all directions…
Test Methods and Specimens8.1 Introduction:8.1.1 Three basic vibratory methods exist:8.1.1.1 Forced vibration of a nonresonant system involving only the specimen,8.1.1.2 Free vibration of a resonant system involving the specimen and a mass, and8.1.1.3 Forced vibration of the above resonant system.8.1.2 The first and third can be broken down further into two kinds of apparatus, those…
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…
