19、of this document, the following terms and definitions apply. 3.1 coated fabric fabric with an adherent, discrete continuous layer of rubber and/or plastic based material on one or both surfaces (see EN 13360) 3.2 soiling process of transferring one or more unwanted substances to the surface of a mat
20、erial NOTE The term “staining“: a special case of soiling caused by one or more dyes or pigments. 3.3 cleanability property of the coated fabric to be restored to its original appearance after cleaning BS EN 15973:2011EN 15973:2011 (E) 5 4 Principle This method provides a procedure for exposing test
21、 specimens to the influence of soiling material under defined conditions, their cleaning and following visual assessment. For soiling three different types of soiling substances are used: a) solid soil and dyes transferred by a soiling cloth; b) an aqueous soil and c) an oily soil. After soiling and
22、 a conditioning period the specimens are cleaned. The specimens are visually assessed before and after cleaning. 5 Apparatus and materials 5.1 Martindale apparatus, according to EN ISO 12947-1. 5.2 Pilling specimen holder heads, for the Martindale apparatus (5.1), including the auxiliary mandrel dev
23、ice for specimen mounting, as defined in EN ISO 12945-2. Pilling specimen holder fitted with ring weight and the nominal 12 kPa loading piece (sum of the mass of the applied load and the mass of the specimen holder assembly of (1 010 15) g). NOTE 1 This exerts a nominal pressure of 1,6 kPa on the te
24、st specimen during the test. NOTE 2 The use of the mandrel is necessary to correctly mount the soiling cloth on the holder and to avoid contact with the soiling surface of the cloth. Use the option that forms a Lissajous figure with a (60 1) mm stroke. It should be noted that this stroke differs fro
25、m the standard machine setting for the textile pilling test. WARNING Some Martindale apparatus have been designed such as the clamping ring is fastened around the abradant table with protuberant screws. Such screws do not allow mechanically the free movement of the pilling specimen holder heads, and
26、 then, such apparatus are not available to perform this test method. 5.3 Wool felt underlay, according to EN ISO 12945-2, cut to a diameter of (90 1) mm, for the pilling holder (5.2). 5.4 Wool felt underlay, according to EN ISO 12947-1, cut to a diameter of (140 1) mm, for the abrading table of the
