3.2 Test chamber See Figure 1. The test chamber shall be designed to provide inside dimensions of (914 × 610 × 914) mm ± 3 mm for width, depth, and height respectively. The interior surfaces shall consist of porcelain-enamelled metal or equivalent coated metal resistant to chemical attack and corrosion, and suitable for cleaning. Panels of 10 mm thickness of […]

Discard the outer layer of the roll to take the sample. The sample shall have an area correspondling to at least 50 cm in the production direction over the width of the produced roll. After taking the sample, it is rlle immediately at right angles to the direction of the production roll, secured with staples or a non-emitting fastening, wrapped […]

1 Scope 1.1 This European Standard covers portable and/or hand-guided machines and appliances equipped with mechanically driven cutting tools. This European Standard specifies requirements for the design and manufacture of portable and/or handguided machines and appliances equipped with electrically, hydraulically or pneumatically driven cutting tools (see Figures 1 to 9), hereinafter referred to as “machines”. The machines covered by this […]

1 Scope This European Standard specifies a method to test the resistance against water penetration of underlays for discontinuous roofing and for walls. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. […]

1 Scope This European Standard specifies:  the composition and tolerances on dimensions of strip produced by rolling in the thickness range from 0,10 mm up to and including 1,50 mm of copper and copper alloys to be tinned, with tin, a tin-lead alloy or other tin alloys;  the composition of material normally used for the melt;  the […]

4.2 System requirements 4.2.1 Personnel The responsibility, authority and the relationship between personnel that manages, performs or verifies work affecting product conformity, shall be defined. This applies in particular to personnel that need to initiate actions preventing product non-conformities from occurring, actions in case of non-conformities and to identify and register product conformity problems. Personnel performing work affecting product conformity […]

1 Scope This document identifies the requirements, the basic performance criteria and evaluation of conformity for precast ribbed elements made of reinforced or prestressed normal weight concrete, used in floors or roofs. The elements consist of a top and/or bottom slab and one or more (usually two) ribs; transverse ribs may also be present. Some examples of precast elements considered […]

1 Scope This European Standard specifies a method for the determination of the staining tendency of bitumen. This method is applicable to bitumen having a Ring-and-Ball softening point greater than or equal to 80 °C. For softer bitumen, the test conditions may be modified by agreement between the involved parties. The procedure described in this document may be used to […]

7 Procedure Once the level filled moulds have been kept at the test temperature for 90 min, remove the moulds from the base plate and the sides of the moulds and transfer the bitumen specimens to the traction plates. Then stretch the specimens at the test temperature ± 0,5 °C and at a speed of (50,0 ± 2,5) mm/min up […]

1 Scope This European Standard specifies a method for determining the tensile properties of a bituminous binder, in particular those of a polymer modified bitumen, by means of a tensile test. NOTE The tensile properties, more particularly the tensile stress, the elongation and energy, at the yield point and on fracture, are customarily used as a criterion for assessing the […]
