20、definitions For the purposes 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 subst
21、ances to the surface of a material 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 DIN EN 15973:2011-05 EN 15973:2011 (E) 5 4 Principle This method prov
22、ides a procedure for exposing test 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
23、c) an oily soil. After soiling and 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), i
24、ncluding the auxiliary mandrel device 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 nom
25、inal pressure of 1,6 kPa on the test 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
26、noted that this stroke differs from 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
27、pilling specimen holder heads, and 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)
28、mm, for the abrading table of the Martindale apparatus (5.1). 5.5 Circular sample cutters, for the specimen and soiling cloth, one cutter with a diameter of at least 140 mm. 5.6 Pipettes, for application of the liquids, accurate to at least 0,1 ml. 5.7 Glass plates, size at least 150 mm x 150 mm. 5.
29、8 Cotton cloth, according to ISO 105-F09, dimension: 70 mm x 70 mm pieces for soiling and pieces of about 150 mm square for cleaning. DIN EN 15973:2011-05 EN 15973:2011 (E) 6 5.9 Soil for dry soiling Soiling cloth1)cut to a diameter 140 mm with following properties: denim with 100 % cotton, 450 g/m
30、(24,5 threads per cm in warp direction, 19,5 threads per cm in weft direction), dyeing with 2,3% indigo blue and 0,5% sulphuric black, soiled with carbon black / olive oil, both at (4 1) g/m. 5.10 Aqueous soil, “instant“ coffee (freeze dried) without sugar2), mixed (2,5 0,1) g coffee to (240 5) ml w
31、ater at 60 C to 80 C and cooled to 40 C. 5.11 Oily soil, paraffin oil (liquid, pure grade, CAS 8012-95-1) containing 0,1 % -carotin (CAS 7235-40-7; purity 95 %). 5.12 Cleaning agent, sodium lauryl ether sulphate (CAS 9004-82-4), 0,5 % solution in water. 5.13 Grey scale, in accordance with EN 20105-A
32、03. 5.14 Other soils and cleaning solutions can be used if requested by the customer, information to be reported. 5.15 Hot air woven, set up to maintain (80 2)C. 6 Preparation and conditioning of test specimens Cut the following specimens for the different procedures: a) for dry soiling: two specime
33、ns 140 mm diameter b) for aqueous soiling: two specimens 100 mm x 100 mm c) for oily soiling: two specimens 100 mm x 100 mm d) for assessment: one specimen about 50 mm x 100 mm Condition the specimens at least 24 h at 20 C and 65 % relative humidity or at 23 C and 50 % relative humidity (according t
34、o EN ISO 2231 respectively, climate A or B). 7 Procedure Perform all described tests in duplicate. 1) “EMPA 128“ is the trade-name of a product supplied by EMPA.

DIN EN 15973:2011-05 EN 15973:2011 (E) 7 7.1 Dry soiling 7.1.1 Carry out the soiling procedure on the abrading table of the Martindale abrasion machine (5.1). Fit the coated textile test specime
37、n backed with the wool felt underlay (5.4) on the abrading table (lower position) with the test side facing upwards as described in EN ISO 12945-2. Check the specimens and backing wool felt are centrally positioned in the clamp of the abrading table. 7.1.2 Fit the soiling cloth (5.9), backed with wo
38、ol felt underlay (5.3), to the pilling holder head (5.2) of the Martindale abrasion machine (5.1) using the auxiliary mandrel device for specimen mounting as described in EN ISO 12945-2. Check for the soiling side of the soiling cloth being on the outside and the cloth and the wool felt underlay are
39、 centrally positioned in the clamp of the holder. The soiling cloth is normally prepared by printing the soiling preparation to one side of the cloth. Be careful that the soiling side is used to rub against the surface of the coated textile. 7.1.3 Adjust the Martindale machine settings for the Lissa
40、jous figure with stroke of (60 1) mm. 7.1.4 Mount the pilling holder with the soiling cloth on the Martindale apparatus. Add immediately the loading piece and run 1000 rubs as defined in EN ISO 12947-1. 7.1.5 Remove the pilling holder with the soiling cloth immediately after finishing 1000 rubs. The
41、 soiling cloth can be discarded. Remove the specimen from the Martindale table. 7.1.6 Place the specimen in the dark for (24 4) h at 20 C and 65 % relative humidity or at 23C and 50 % relative humidity (according to EN ISO 2231 respectively, climate A or B). If required, a part of the soiled specime
42、n can be aged, directly after soiling, (24 0,5) h at (80 2) C in a hot air oven (5.15). After ageing the specimens shall be placed 1 h at 20 C and 65 % relative humidity or at 23 C and 50 % relative humidity (according to EN ISO 2231 respectively, climate A or B) before cleaning. 7.1.7 Clean the spe
43、cimen as described in 7.4, allow it to dry and condition the specimen in the dark for at least 16 h at 20 C and 65 % relative humidity or at 23 C and 50 % relative humidity (according to EN ISO 2231 respectively, climate A or B). Assess the soiled and cleaned specimen as described in 7.5. 7.2 Aqueou
44、s soiling 7.2.1 Place the specimen flat on a glass plate (5.7). Place a 70 mm x 70 mm piece of cotton cloth (5.8) in the centre of the specimen surface. Apply (2,0 0,1) ml of aqueous soil so that all liquid remains uniformly on the cotton cloth. NOTE For mesh fabrics or perforated materials, apply (
45、1,0 0,1) ml, if necessary. This quantity should be reported. 7.2.2 Store the specimen on a glass plate together with the soil and the cotton cloth for (4 0,5) h at 20 C and 65 % relative humidity or at 23 C and 50 % relative humidity (according to EN ISO 2231 respectively, climate A or B). 7.2.3 Rem
46、ove the cotton cloth. Remove carefully any excess soil using a new dry cotton cloth patting the surface of the specimen dry without rubbing. 7.2.4 Clean the specimen as described in 7.4, allow it to dry and condition the specimen in the dark for at least 16 h at 20 C and 65 % relative humidity or at
47、 23 C and 50 % relative humidity (according to EN ISO 2231 respectively, climate A or B). 7.2.5 Assess the soiled and cleaned specimen as described in 7.5. DIN EN 15973:2011-05 EN 15973:2011 (E) 8 7.3 Oily soiling 7.3.1 Place the specimen flat on a glass plate (5.7). Place a 70 mm x 70 mm piece of c
48、otton cloth (5.8) in the centre of the specimen surface. Apply (2,0 0,1) ml of oily soil slowly on the cotton cloth. Take care that all liquid remains on the cotton cloth. NOTE For mesh fabrics or perforated materials, apply (1,0 0,1) ml, if necessary. This quantity shall be reported. 7.3.2 Store the specimen on a glass plate together with the soil and the cotton cloth in the dark for (4 0,5
