EN ISO 12947-3:1998 BSI 02-2000iii Foreword ISO (the International Organization for Standardization) is a wor
22、ldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on
23、 that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted
24、in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Int
25、ernational Standard ISO 12947-3 was prepared by Technical Committee ISO/TC 38, Textiles. ISO 12947 consists of the following parts under the general title Textiles Determination of the abrasion resistance of fabrics by the Martindale method: Part 1: Martindale abrasion testing apparatus; Part 2: Det

32、tions For the purposes of this part of ISO 12947 the definitions given in ISO 12947-1 and ISO 12947-2 apply. 4 Principle A circular specimen is mounted in a specimen holder and, subjected to a defined load, is rubbed against an abrasive medium (standard fabric) in a translational movement tracing a
33、Lissajous figure, the specimen holder being additionally freely rotatable around its own axis perpendicular to the plane of the specimen. The evaluation of the abrasion resistance of the textile fabric is determined from the mass loss of the test specimens. The specimens are mounted in the specimen
34、holders with foam backing. Specimens with a mass per unit area greater than 500 gm2 are mounted in the specimen holders without foam. Pile fabrics and cord fabrics which are tested without foam backing are subjected to a specified preparatory treatment (see 7.5.2). Two abrasion parameters are specif
35、ied. The total effective mass of the abrasion load (i.e. the mass of the specimen holder assembly and the appropriate loading piece) are: a) (795 7) g for workwear, upholstery, bed linen and fabrics for technical use (nominal pressure of 12 kPa); b) (595 7) g for apparel and household textiles, excl
36、uding upholstery and bed linen (nominal pressure of 9 kPa). The mass loss of the test specimen is determined for each of the established numbers of rubs according to the number of rubs at which specimen breakdown occurs (see Table 1). 5 Apparatus and materials In addition to the test apparatus and a
37、uxiliary materials specified in ISO 12947-1, a balance, having an accuracy of 1 mg, is required. 6 Conditioning and testing atmosphere The standard temperate atmosphere for conditioning and testing textiles as defined in ISO 139 shall be used, i.e. a temperature of (20 2) C and a relative humidity o

(Revision of ISO 2859:1989) EN ISO 12947-3:1998 2 BSI 02-2000 Table 1 Test intervals for mass loss testing 7 Sampling and preparation of test specimens 7.1 General Perform sampling in accordance with statistical rules (see ISO 2859-1). Ensure throughout sampling and s
39、pecimen preparation that handling imposes the minimum possible tensile stress so as to prevent incorrect extension of the textile fabric. 7.2 Selection of the laboratory sample Select the laboratory sample from a test lot to be representative of properties of the textile fabric. Check the representa
40、tive nature of sampling from the start or end of a textile fabric. Take the laboratory sample from across the full fabric width. 7.3 Sampling of the test specimens from the laboratory sample Before sampling the test specimens from the laboratory samples, condition the laboratory samples, free from t
41、ension, for at least 18 h on a smooth horizontal surface with free access of air exposed to the standard atmosphere specified in clause 6. Take the test specimens at least 100 mm from the edge distributed across the entire laboratory sample. Take a sufficient number of test specimens to be in accord
42、ance with statistical rules (see 7.1). For woven fabrics, take the specimens so that they each contain different warp and weft threads. For patterned fabrics or fabrics with textured surface, take care to ensure that the test specimens contain all characteristic parts of the pattern ensuring that th
43、e parts of the pattern likely to be sensitive to abrasion are contained in the test specimens. 7.4 Dimensions of specimens and auxiliary materials 7.4.1 Dimensions of the test specimens The diameter of the test specimens shall bemm. 7.4.2 Dimensions of abradant The dimensions of the abradant shall b
44、e at least 140 mm in diameter or length and width. 7.4.3 Dimensions of the abradant felt substrate The diameter of the woven wool abradant felt underlay shall bemm. 7.4.4 Dimensions of the specimen holder underlay foam backing The diameter of the specimen holder underlay foam backing shall bemm. 7.5
45、 Specimen preparation for specific fabrics 7.5.1 Stretch fabrics See Annex A, clause A.1. 7.5.2 Cord fabrics and pile fabrics See Annex A, clause A.2. 7.6 Preparation and mounting of the test specimens and cutting-out and mounting of the auxiliary materials 7.6.1 Preparation Stamp or cut out the tes
46、t specimens from the laboratory sample. Give particular attention to the clean status of the cut edges to prevent the occurrence of unwanted material loss in subsequent handling. Determine the mass of each conditioned test specimen to the nearest 1 mg by weighing. Prepare the auxiliary materials in
47、a similar fashion from the available pieces of woven fabric, felt or foam. NOTEThe auxiliary materials may under some circumstances be obtained already prepared to the required dimensions.
