This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a

13、 CEN member into its own language and notified to the Central Secretariat has the same status as the official versions.

This European Standard shall be given the st

15、atus of a national standard, either by publication of an identical text or by endorsement, at the latest by April 1998, and conflicting national standards shall be withdrawn at the latest by April 1998. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the fo

19、 specimen holder and abradant: 25,4 mm 0,2 mm; abrading pressure: 5,4 N/m 2 0,1 N/m 2 . 4.2 Standard abradant fabric 2) , a plainweave filter fabric having the following characteristics: material: polyester monofilament; thread diameter: 150mm 10mm; mesh count: (23,3 1) threads per centimetre (warp

20、and weft); fabric thickness: 260mm 10mm; mass per unit area: 118 g/m 2 5 g/m 2 . The standard abradant is mounted in the abradant holder over a piece of wool felt. The felt used is of mass 750 g/m 2 50 g/m 2 and 2,5 mm 0,3 mm thick 3) . 4.3 Weighing balance, capable of measuring masses approximately

21、 of 350 g with an accuracy of 10 mg. 4.4 Soft bristle brush, for removal of loosened fibre prior to weighings. 5 Sampling and preparation of test specimens Using a cutting die and press, cut pile side up four circular specimens of approximately 37,5 mm diameter from the material to be tested, follow

22、ing the procedure described in ISO 1957. 6 Conditioning Condition the test specimens left flat, pile side uppermost, in the standard atmosphere for testing textiles 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 t

23、he 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 specimen 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 comple

24、te with mounted specimen and record the initial mass (m i )t o 10 mg accuracy. 7.3 Fit the specimen holder in position on the machine. 7.4 Insert a new disc of the standard abradant with the felt backing in the abradant holder and fit the holder into position on the machine.Page 4 EN 1813 : 1997 BSI

25、 1998 A new piece of felt shall be used for each carpet. 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, repla

26、ce the felt. 7.5 Set the counter for 5000 cycles, lower 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

27、 mass (m f ) to 10 mg accuracy. 7.7 If the specimen shows wear to backing at 5000 cycles, repeat the test using 2500 cycles, record the final mass to 10 mg accuracy (m f2,5 ). 8 Calculation and expression of results 8.1 Determine the mass loss for each of the four specimens by the following equation

28、: m L = m i 2 m f where m L is the absolute mass loss, in grams; m i is the initial mass of the specimen, in grams; m f is the final mass of the specimen, in grams. If the 2500 cycles end point is used, the calculation is: m L =2 ( m i 2m f2,5 ) where m f2,5 is the final mass of specimen after 2500

29、cycles, in grams. 8.2 Calculate the average mass loss per 5000 cycles in grams, 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 te

30、sted, including type, source, colour and manufacturers reference; c) previous 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.blankBSI 389 Chiswick High Road London W
