10、 Standard has been prepared by Technical Committee TCI/66. It is a revision of BS 2543:1995, which is withdrawn. The revision has been prompted by the publication of BS EN 14465:2003, Textiles Upholstery fabrics Specification and methods of test, which specifies a set of properties relevant to the a
11、ssessment of upholstery fabric for indoor furniture and appropriate test methods to determine these properties. However, the European Standard does not provide a designated product profile grading system adapted to each specific type of upholstery end use application. This revision provides the mini
12、mum product profile for upholstery fabric found to be useful to the users of BS 2543:1995 and cross-refers to the categories provided in BS EN 14465:2003. BS 2543:2004 only contains references to properties listed in BS EN 14465:2003 where anything other than the minimum level would be stated. This
13、publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. In particular, attention is drawn to: Sale of Goods Act 1979 The Supply

33、and flocked fabrics not included in BS EN 14465:2003 NOTE See Table 3. A.1 Method of test for pile tuft and/or fibre loss by reverse abrasion Carry out the test in accordance with the test detailed in BS EN ISO 12947-2 with a pressure of 12 kPa 3 kPa, with the following modifications. a) Interchange
34、 the positions of the fabric test specimens and the reference abradant. Mount the test specimens 150 mm square or 150 mm in diameter over the backing felt on the abrading table, with the face of each specimen in contact with the felt, and mount the 38 mm diameter pieces of reference abradant in the
35、specimen holders over the disc of polyetherurethane foam in all cases. b) Carry out the test for 5 000 cycles then remove the test specimens. Place them face downwards on a laboratory light-box or over a similar source of illumination. Assess the pile loss against the scale given in Table A.1 NOTE R
36、emoval of pile tufts is manifested by transmission of light through any holes produced. c) Reverse the test specimens and assess the effect of the test on the face of the fabric against the scale given in Table A.1. A.2 Method of test for scuffing (surface pile loss) A.2.1 General Carry out the test
37、 in accordance with BS 4655:1986 with the modifications shown in A.2.2 to A.2.5. A.2.2 Principle The face side of a fabric, which is supported over a piece of reference abradant fabric is rubbed, under controlled conditions, by the edge of a metal disc. The test is intended to assess the tendency of
38、 all types of cut or non-loop pile upholstery to lose substantially complete lengths of pile from the surface of the fabric. To the extent that this tendency generally requires a harsh abrasive force from a relatively keen edged object, it often relates to minor unspecified abuse of the upholstery.
39、A.2.3 Apparatus The finger of the testing device is replaced by a similar attachment containing a slot that is capable of accommodating a metal disc having the material properties and dimensions of an unused 2 pence coin (7), allowing the disc to project forward from the face of the attachment and t
40、o subtend an angle of 45 to the plane of the platform (see Figure A.1). The disc is rotated through 90 immediately on completion of a test on one specimen to present an unused quadrant. When four such tests have been carried out the disc may be reversed to enable four more tests to be performed. Aft
41、er eight tests have been completed, the disc is replaced by a new one. A.2.4 Preparation of test specimens Select warpwise and weftwise specimens such that in the case of the following types of fabric representative areas of pattern or pile are tested: a) multi-patterned fabrics; b) figured velvets;
42、 c) fabrics containing mixtures of “V” and “W” tufts; d) other varying types of pile. In the case of figured velvets, representative areas include maximum available areas of uninterrupted pile and, in the case of velvets containing patterned and plain areas, parts of the pattern containing the large
43、st areas of plain pile available are sampled, as well as patterned areas. Where more than one area needs to be tested, the test is carried out on three test specimens from each area.BS 2543:2004 BSI 15 September 2004 5 A.2.5 Procedure Mount the test specimen face side uppermost over a similar sized
44、piece of reference abradant fabric as described in 3.3 of BS 4655:1986. Position the abradant fabric with its expanded PVC face uppermost, i.e. in contact with the test specimen. Position both the specimen and the abradant fabric with their longest edges parallel to the longitudinal axis of the plat
45、form of the testing device such that the direction of the lay of the pile is away from the tension wheel. Secure both fabrics at the mounting pins and tension wheel ends of the testing device. For fabrics other than flocked pile fabrics, after 30 rub cycles have been applied (i.e. 30 movements in ea
46、ch direction), raise the movable arm of the testing device to assess the effect on the pile. For flocked pile fabrics, test both dry and wet specimens. Test dry specimens for 60 rub cycles. Prepare wet specimens by immersing fresh dry specimens in water and allowing each to drain until it contains i
47、ts own mass of water. Transfer the specimen immediately to the testing device and subject to 15 rub cycles. After testing, assess the specimens as indicated in Table A.1. Table A.1 Ratings for pile loss and for scuffingA.3 Test report Record the pile or fibre loss rating, with an indication of the t
48、est specimen direction (e.g. warpwise or weftwise) appropriate to each result. If a test result in one specific area of the sample is rated significantly higher than that in the remaining areas, mention it in the report. Additionally, in the case of patterned velvets, indicate in the report whether
49、the loss of pile is restricted to, or is more noticeable on, specific areas of pattern. NOTE In assessing the significance of the results, it should be noted that pile loss will occur more easily on test specimens which have lost pile fibre generally due to abrasive wear. Thus, a velvet with a relatively low abrasion test result (A.1) can lose pile tufts rather more quickly in use than one which is more resistant to attritive forms of abrasive wear. Pile l
