BS EN 530:2010EN 530:2010 (E) 4 Introduction This document describes testing of abrasion re

20、sistance of materials for protective clothing. It should be noted that in order to carry out the abrasion test according to this document the following parameters are to be specified: abradant; replacement of the abradant; conditioning and testing atmosphere; debris removal; pressure applied; judgem

21、ent of deterioration in case of using method 1; number of cycles in case of using method 2. In general these parameters are specified in product standards. BS EN 530:2010EN 530:2010 (E) 5 1 Scope This European Standard describes two test methods on abrasion resistance of materials using the same abr

22、asion apparatus. The first method describes the determination of the abrasion resistance of protective clothing materials. The second method describes abrasion pre-treatment of these materials where the test specimens are used afterwards in other test methods or for evaluating the remaining protecti

23、ve properties. The abradant is regarded to be a woven wool fabric for the purposes of this standard. If other abradants (e.g. glass paper) are used, they should be specified in the requirement standard. Mounting instructions of special abradants should be described in requirement standards. This Eur

24、opean Standard is applicable as a reference standard on abrasion for standards and specifications on protective clothing textile materials. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited a

25、pplies. For undated references, the latest edition of the referenced document (including any amendments) applies.

26、dale method Part 1: Martindale abrasion testing apparatus (ISO 12947-1:1998) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 specimen breakdown in woven fabrics, when two separate threads are completely broken; in knitted fabrics, when one th

27、read is broken down causing a hole to appear; in pile fabrics, when the pile is fully worn off; in nonwovens, when the first hole resulting from the wear is of a diameter at least equal to 0,5 mm; in coated material, when coating surface has the first hole resulting from the wear of a diameter at le

29、ange it BS EN 530:2010EN 530:2010 (E) 6 4 Methods of test 4.1 Principles The abrasion test using the Martindale abrasion machine is presented in two methods of operation. Method 1: Determination of abrasion resistance Determination of abrasion resistance employs the instrument in the conventional ma

30、nner and produces an abraded disc of material 38 mm in diameter. This is convenient where only the loss of finish or appearance, or the mass or volume of abrasion loss, is to be determined and requires only small amounts of material to be tested. Method 2: Pre-treatment procedure Pre-treatment proce

31、dure employs the instrument in inverted mode, i.e. the specimen is placed on the abradant table instead of in the test piece holder and the abradant is mounted in the test piece holder. This provides an abraded area which allows post-abrasion testing or evaluation to be carried out. 4.2 Conditioning

32、 and testing atmosphere Condition the material to be tested, and the abradant, in the standard atmosphere in accordance with EN ISO 139:2005 unless otherwise specified in the requirement standard. Conduct the test in the same atmosphere. If other atmosphere is used, it shall be stated in the test re

33、port. 5 Apparatus and materials 5.1 Abrasion machine Martindale abrasion machine as described in EN ISO 12947-1. 5.2 Abradant Woven wool fabric conforming to EN ISO 12947-1:1998, Table 1. If other abradants are used, these shall be specified in the specific product requirement standard. 5.3 Foam Pol

34、yetherurethane foam material as specified in EN ISO 12947-1:1998, Table 3. Foam is used in test pieces holders under specimen or abradant. When tested material or abradant have a mass per unit area more than 500 g/m, foam is not used. 5.4 Felt Felt backing as specified in EN ISO 12947-1:1998, Table

35、2. Felt is used in abrasion tables under the tested material or abradant. 5.5 Cutter Punch or press cutter, to cut a circle of (385,00+) mm in diameter. BS EN 530:2010EN 530:2010 (E) 7 5.6 Magnifying glass or microscope Magnifying glass or stereo microscope, e.g., 8x magnification. 5.7 Useful life o

36、f auxiliary materials Renew the abradant for every test. For abrasion tests with more than 50 000 rubs, change the abradant after every 50 000 rubs. Inspect the felt for soiling and wear after every abrasion test. If soiling or detectable wear shows visible or touchable change (e.g. pilling) in the

37、surface of the felt, replace the felt. When foam is used in abrasion testing, use a new piece for every abrasion test. 6 Procedure of Method 1: Determination of abrasion resistance 6.1 Test specimen Using the punch or press cutter, take at least four pieces for test specimens. Exclude the selvedge a

38、rea at least 100 mm from the edge when cutting the specimens at random from the entire material. For woven fabrics, take the specimens so that they each contain different warp and weft threads. Specimens shall not include seams. If the end point of the test is expressed in terms of mass loss, determ

39、ine the mass of each specimen taken, to an accuracy of 1 mg before the test starts. 6.2 Setting up the machine 6.2.1 Mounting specimen in test piece holder Place the ring of the test piece holder in position on the mounting plate provided on the base of the machine. Insert the specimen face side dow

40、nwards, centrally on the ring. Place the foam backing on top. Foam shall not be used for test specimens with a mass per unit area of more than 500 g/m2. Place the metal insert carefully and centrally on top of the specimen or on top of the foam and specimen, so that its hollowed side faces upwards,

41、and press down. Ensure that the specimen is retained in a wrinkle-free condition during the further assembly with the test piece holder. NOTE When screws are used for this assembly, the following procedure should be followed: Hold the ring containing the specimen and the metal insert firmly in the m

42、ounting plate, start to screw the top of the test piece holder on to the ring, taking care that the screw threads are not crossed. Having started the screwing down operation, use both hands to maintain a continuous downward pressure on the assembly, against the mounting plate. 6.2.2 Mounting the wov

43、en wool fabric abradant on abrading table Cut circular pieces with a diameter of (140 5) mm of abradant to fit the abrading table and cut the same number and size of felt backings. Use a new abradant on the abrasion tables. Place the felt backing on the abrading table and place the abradant over the

44、 felt. Check that weft and warp of the woven wool abradant lie parallel to the edges of the machine frame. Compress the felt and abradant on the abrading table with a pressing weight described in EN ISO 12497-1. Fit the clamping ring (or appropriate device) and secure the felt and abradant firmly. R

45、emove the pressing weight. Ensure that the abradant is retained in a wrinkle-free condition. BS EN 530:2010EN 530:2010 (E) 8 6.2.3 Wrinkles If the specimen or the abradant cannot be mounted in a wrinkle-free position, the foam or felt backing shall be omitted, but this shall be stated in the test re

46、port. 6.2.4 Preparation of the abrasion machine After mounting the specimens in the test piece holders and the abradant on the abrading table, place the test piece holder guide plate in position on the Martindale apparatus. Correctly position the test piece holders and spindles with additional loadi

47、ng pieces (9 kPa or 12 kPa) at their respective work stations. Use pressure spindle 9 kPa unless otherwise specified in the requirement standard. NOTE Spindles and additional loading pieces (9 kPa or 12 kPa) are described in EN ISO 12947-1. 6.3 Procedure Preset intervals of rubs to the abrasion mach

48、ine as the requirement standard states. If intervals are not given in the requirement standard, apply the relevant test series given in Table 1. Estimate the possible breakdown point of the test material and choose a suitable test series. The test may be repeated if the estimation is inaccurate. Tab

49、le 1 Test series Test series Number of rubs n at which specimen breakdown occurs Test intervals rubs a n 5 000 Every 1 000 b 5 000 n 20 000 Every 2 000 c 20 000 n 40 000 Every 5 000 d 40 000 n Every 10 000 NOTE For diagnostic purposes the test interval for each test series may be reduced as the end point is approached. After preparing the Martindale machine, set the first test interval according to Table 1 or the requirement standard. Switch on the machine. C
