18、ndard specifies the characteristics of heterogeneous resilient floor coverings based on polyurethane with thermosetting properties supplied in either roll, planks or tile form. This specification does apply for floor covering consisting of a wear layer and other compact layers made from polyurethane
19、 which differ in composition, chemical crosslinking and/or design and can contain a decor layer, reinforcement and other backing. This specification does not apply for floor coverings that are specified in EN ISO 10582, EN ISO 24011, EN 1817 or EN 14565. To encourage the consumer to make an informed
20、 choice, the standard includes a classification system (see EN ISO 10874) based on intensity of use, which shows where these floor coverings should give satisfactory service. It also specifies requirements for marking. 2 Normative references The following documents, in whole or in part, are normativ

DIN EN 16776:2016-09 EN 16776:2016 (E) 9 Annex A (normative) Method for test for resistance to scratching A.1 Introduction This method of test specifies a pro
43、cedure to assess the appearance of scratches on resilient floor covering surfaces under laboratory conditions. A.2 Principle A test piece mounted on a horizontal rotating plate is scratched by a defined steel pin. The pin can be loaded with different weights. The load at which the pin causes an unin
44、terrupted scratch of defined characteristics is used for the ranking of the product. A.3 Apparatus and materials NOTE The item numbers in parentheses in A.3.1.1 to A.3.1.6 refer to Figure A.1. A.3.1 Scratch tester (Figure A.1), consisting of A.3.1.1 to A.3.1.6 A.3.1.1 Stand with a device to indicate
45、 the horizontal, e.g. a spirit level A.3.1.2 Turntable (4) freely rotating, motor-driven, for supporting the test piece, rotating around its vertical axis at (35 5) mm per second at the position where the scratch is made A.3.1.3 Clamping disc (6) to keep the test specimen flat A.3.1.4 Arm (5) with a
46、 holder for the steel pin (3), mounted on a ball bearing, with horizontal axis. This arm is engraved with a scale (1) and is made adjustable in order to ensure that it is always horizontal, independent of the thickness of the test piece, when the steel pin touches the surface of the specimen. A.3.1.
47、5 Movable weight (2) that can be moved along the arm (5) The mass of the weight together with the effective mass of the arm presses the steel pin onto the surface to be tested. The force exerted on the steel pin shall be accurate to 0,01 N, when measured at the mounting device for the pin. A.3.1.6 S
48、teel pin (3) (also shown in Figure A.2), made from tungsten carbidecobalt (WCCo) hard metal, HIP treated (hot isostatic pressed). The steel pin shall have a diameter of 3 mm 0,02 mm. The conical tip shall have a diameter of 0,5 mm 0,02 mm and an angle of 45 1, as indicated in Figure A.2. DIN EN 1677
