27、 the secretariat of which is held by DIN. This document is currently submitted to the CEN Enquiry. This document will supersede EN 530:1994. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential require
28、ments of EU Directive 89/686/EWG. Licensed CopyChinese University of Hong Kong, 21/10/2008 08:05, Uncontrolled Copy, (c) BSI prEN 530:2008 (E) 4 1 Scope This European Standard describes two methods on abrasion resistance of materials using the same apparatus. This standard is applicable as reference
29、 standard on abrasion for standards and specifications on protective clothing. The first method describes the determination of the abrasion resistance of protective clothing materials and the second method describes abrasion pre-treatment of these materials where the test samples afterwards are used
30、 in evaluation of the remaining protective properties. 2 Normative references The following referenced documents are indispensable for the application of this document.

35、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 0,5mm. Licensed CopyChinese University of Hong Kong, 21/10/2008 08:05, Uncontrolled Copy, (c) BSI prEN 530:2008 (E) 5 4 Methods of test 4.1 Principles The abrasion test using
36、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 manner and produces an abraded disc of material 38 mm in diameter. This is convenient where only th
37、e 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: Pretreatment procedure Pretreatment procedure employs the instrument in inverted mode, i.e. the test piece is placed on the abradant table i
38、nstead of in the test piece holder and the abradant is mounted in the test piece holder. This provides an abraded area which enables post-abrasion testing to be carried out. 4.2 Apparatus 4.2.1 Abrasion machine Abrasion machine, of the type described by Martindale, (see annex B), and fulfilling the
39、following requirements : Rotational speed of each of the outer pegs: (47,5 2,5) min-1 Drive ratio outer pegs : inner pegs: 32 / 30 Dimensions of the Lissajous figure: (60 1) mm Face diameter of specimen holder insert: (28,65 0,25) mm Combined total mass of specimen holder, spindle and weight: (595 7
40、) g or (795 7) g The specimen holders and abrading tables shall be plane and parallel over their entire surfaces. The drive from the motor to the machine shall be connected to a counter and switch so that the revolutions of the outer pegs are indicated and that the machine may be stopped after a pre
41、determined number of cycles has been measured by the counter . NOTE Information concerning the assembly, maintenance and calibration of the abrasion machine is given in annex A. It is considered advisable that these recommendations are followed, if excessive variability of the test result is to be a
42、voided.

44、A polyurethane foam material (3 1) mm thick, having a density of (30 1) kg/m3, used for fabrics having a mass per unit area less than 500 g/m2 as an underlay for the test specimen or fabric abradant mounted in the specimen holder. Place circles of foam of diameter 38,0 0+5 mm between the test specim
45、en or abradant and the specimen holder insert. Store the foam material in the dark at room temperature. 4.2.4 Felt Felt backing, either a non-woven of (625 50) g/m2and approximately 2,5 mm thick, or a woven felt of (750 50) g/m2 and approximately 2,5 mm thick . 4.2.5 Cutter Punch or press cutter, to
46、 cut a circle of at least 38 mm in diameter. 4.3 Conditioning and testing atmosphere Condition test pieces and the abradant in atmosphere A in according with EN ISO 139:2005, unless otherwise specified. Conduct the test in a room with a temperature not exceeding the range of 15 C to 30 C. Specimens
47、are to be tested in their natural state. 4.4 Procedure of Method 1: Determination of abrasion resistance 4.4.1 Test pieces Using the punch or press cutter (4.2.5) take at least four pieces at random from the entire material under test. These shall not include seams. If the end point of the test, req
48、uired by the relevant product specification, is expressed in terms of mass loss, determine the mass of each test piece taken, to an accuracy of 1 mg.
