The standard abradant is mounted in the abradant holder over a piece of
22、wool felt. The felt used is of mass 750 g/m250 g/m2and 2,5 mm0,3 mm thick3). 4.3 Weighing balance, capable of measuring masses approximately of 350 g with an accuracy of10 mg. 4.4 Soft bristle brush, for removal of loosened fibre prior to weighings. 5 Sampling and preparation of test specimens Using
23、 a cutting die and press, cut pile side up four circular specimens of approximately 37,5 mm diameter from the material to be tested, following the procedure described in ISO 1957. 6 Conditioning Condition the test specimens left flat, pile side uppermost, in the standard atmosphere for testing texti
24、les defined in EN 20 139, for a minimum of 24 h. 7 Test procedure 7.1 Mount a specimen in the specimen holder, taking care to ensure that the specimen is flat. If necessary, trim the outer tufts to facilitate entry into the holder. Using a tensioning device (usually a torque wrench) clamp the specim
25、en in the holder with a torque of aproximately 6,5 Nm and brush any loose tufts from the pile surface. 7.2 Weigh the specimen holder complete with mounted specimen and record the initial mass (mi) to 10 mg accuracy. 7.3 Fit the specimen holder in position on the machine. 7.4 Insert a new disc of the
26、 standard abradant with the felt backing in the abradant holder and fit the holder into position on the machine.

27、. It shall be used for no more than 20000 cycles in total and it shall be reversed after 10000 cycles. If the felt is heavily contaminated by fibres, as seen by change in colour or by dust visible on the surface and not possible to remove, replace the felt. 7.5 Set the counter for 5000 cycles, lower
28、 the abradant holder on to the specimen, and start the machine. 7.6 Remove the specimen holder from the machine, brush off any loosened fibres and weigh (complete with specimen) within 2 min of the end of the abrasion treatment. Record the final mass (mf) to 10 mg accuracy. 7.7 If the specimen shows
29、 wear to backing at 5000 cycles, repeat the test using 2500 cycles, record the final mass to 10 mg accuracy (mf2,5). 8 Calculation and expression of results 8.1 Determine the mass loss for each of the four specimens by the following equation: mL= mi2 mf where mLis the absolute mass loss, in grams; m
30、iis the initial mass of the specimen, in grams; mfis the final mass of the specimen, in grams. If the 2500 cycles end point is used, the calculation is: mL= 2(mi2 mf2,5) where mf2,5is the final mass of specimen after 2500 cycles, in grams. 8.2 Calculate the average mass loss per 5000 cycles in grams
31、, the standard deviation, and the coefficient of variation. 9 Test report The test report shall contain the following information: a) reference to this standard, i.e. EN 1813; b) a complete identification of the product tested, including type, source, colour and manufacturers reference; c) previous
32、history of the sample; d) the average mass loss and coefficient of variation; e) any deviation from this standard, including the number of cycles used, if different from 5000 cycles.
