23、 2: Determination of specimen breakdown. 3 Definitions For the purposes of this part of ISO12947 the definitions given in ISO12947-1 and ISO12947-2 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

24、fabric) in a translational movement tracing a 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 specime

25、ns. The specimens are mounted in the specimen holders with foam backing. Specimens with a mass per unit area greater than500gm 2are 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 (se

26、e7.5.2). Two abrasion parameters are specified. 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 of12kPa); b) (595 7)g fo

27、r apparel and household textiles, excluding upholstery and bed linen (nominal pressure of9kPa). 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 (seeTable 1). 5 Apparatus and materials In a

28、ddition to the test apparatus and auxiliary materials specified in ISO12947-1, a balance, having an accuracy of1mg, is required. 6 Conditioning and testing atmosphere 1) To be published. (Revision of ISO 2859:1989) A standard temperate atmosphere for conditioning and testing textiles shall be used,

29、i.e. a temperature of (20 2) C and a relative humidity of (65 2) % as defined in ISO 139. 1BS EN ISO 12947-3:1998 2 BSI 2008 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 ISO2859-1). En

30、sure throughout sampling and specimen 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 textil

31、e fabric. Check the representative 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 l

32、aboratory samples, free from tension, for at least18h on a smooth horizontal surface with free access of air exposed to the standard atmosphere specified in clause6. Take the test specimens at least100mm from the edge distributed across the entire laboratory sample. Take a sufficient number of test

33、specimens to be in accordance with statistical rules (see7.1). 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

34、pattern ensuring that the 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 7.4.2 Dimensions of abradant The dimensions of the abradant shall be at least140mm in diam

35、eter 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 7.5 Specimen preparation for specific fabrics 7.5.1 Stretch fabrics SeeAnnex A, clauseA.1. 7.5.2 C

36、ord fabrics and pile fabrics SeeAnnex A, clauseA.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 test specimens from the laboratory sample. Give particular attention to the clean status of the cut ed

37、ges to prevent the occurrence of unwanted material loss in subsequent handling. Determine the mass of each conditioned test specimen to the nearest1mg by weighing. Prepare the auxiliary materials in a similar fashion from the available pieces of woven fabric, felt or foam. NOTEThe auxiliary material

38、s may under some circumstances be obtained already prepared to the required dimensions.

41、 the mounting device on the machine frame. Place the test specimen in the specimen holder nut with wear side downward carefully and centrally. For test specimens having a mass per unit area of less than500gm 2place the foam backing on the test specimen. NOTEAvoid fabric distortion when mounting the

42、test specimen. Place the specimen holder insert in the specimen holder nut, place the specimen holder body over the nut and screw down tightly. 7.6.3 Mounting of the abradant Move the specimen holder guide plate to ensure free access to the abrading tables. Place the felt on the abrading tables and

43、place the abradant over the felt. Fit the abradant so that the two thread systems of the woven fabric lie parallel to the edge of the machine frame. Compress the felt and abradant on the abrading table with a pressing weight having a mass of(2,5 0,5)kg and a diameter of(120 10)mm. Fit the clamping r

44、ing and secure the felt and abradant firmly. Remove the pressing weight. 7.7 Useful life of auxiliary materials Renew the abradant for every test. For abrasion tests with more than50000 rubs, change the abradant every 50000rubs. Inspect the felt for soiling and wear after every abrasion test. If soi

45、ling or detectable wear occur replace the felt. Both sides of the felt may be used. Where foam is used in abrasion testing, use a new piece for every abrasion test. 7.8 Preparation of the abrasion machine After mounting the test specimens and auxiliary materials place the specimen holder guide plate

46、 in position and correctly position the specimen holders and spindles at their respective work stations and place the loading piece prescribed for the abrasion test on each specimen holder spindle. 8 Abrasion test procedure Preselect the number of rubs according to the relevant test series listed in

47、Table 1 for the abrasion test previously determined by ISO12947-2. Where necessary complete the preparatory treatment of the specimens in accordance with7.5.2 and the preparation in accordance with clause7. Start the abrasion tester. Abrade the required number of specimens of known mass to each of t

48、he selected test intervals in the chosen test series e.g.for test series a inTable 1 abrade separate sets of specimens to100,250,500 etc.rubs. Remove the load from the specimens and carefully remove the specimen holders from the testing machine. Check the specimens for abnormal surface change (e.g.n

49、eps or pilling, creases, tuft loss in pile textiles). In the event of such abnormalities reject the test specimens. If all specimens exhibit such changes do not continue the test. If only individual specimens are abnormal, repeat the test until the required number of specimens has been tested. The abnormalities observed and the number of abnormal test specimens shall be recorded in the test report. To d
