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…
C.1 Principle A specimen of the material shall be mounted in a vertical plane and shall be subjected to a continuous spray of water droplets. Measurements shall be made of the coefficient of retroreflection of the wetted surface while the spray is maintained, simulating the optical behaviour of a surface in a shower of rain….
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…
6 Apparatus and Materials6.1 Flammability Tester,with a separate timer capable of providing flame impingement on the specimen for 1 + 0.01 s as shown in Fig. 1 or an equivalent electrically operated tester equipped with an automatic electric timer, as described in Annex A1. Testers are normally supplied with specimen holders.6.2 Brushing Device, as shown…
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…
