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…

3 Fire behaviour3.1 Requirements and testingThe material used for pipes and fittings shall fulfil the requirements for class B1 building materials, as specified in DIN 4102-1. Fire behaviour shall be tested as in DIN 4102-1, with the exception of pipes and fittings with wall thicknesses as in DIN 4102-4. 4 Conformity assessment (quality control)4.1 General…

Annex BHoliday detection test B.2 EquipmentB.2.1 Holiday detector, adjustable, high-voltage, with ± 10 % reading accuracy, equipped with a soundand/or light signal.B.2.2 Scanning electrode, in the form of a…

A wire cable constant temperature water bath testing machine is a piece of equipment used to test the performance and quality of wire and cable products under a constant temperature water bath environment. The testing machine typically consists of a water tank, a temperature control system, a wire or cable holder, and a monitoring system….

1 Scope1.1 This specification covers high density polyethylene (HDPE) geomembranes with a formulated sheet density of 0.940 g/ml, or higher, in the thickness range of 0.75 mm (30 mils) to 3.0 mm (120 mils). Both smooth and textured geomembrane surfaces are included.1.2 This specification sets forth a set of minimum, physical, mechanical and chemical properties…

6 Apparatus6.1 Penetrometer, for applying the standard needle to the surface of the sample specimen and for measuring the extent of penetration at the conclusion of the test. The penetrometer shall be constructed in such a manner that the accurate placement of the tip of the needle at the level surface of the specimen may…
