The work of preparing International Standards is normally carried out th
19、rough 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 that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collab
20、orates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval
21、 criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subje
22、ct of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade

25、999) which has been technically revised. The changes are as follows: in Clause 4, a non-flexible cardboard support or a solid board equivalent to it for thin sample fixation has been added as 4.9 and the part of the body text related to it in the third paragraph of 4.1 has also been added accordingl
26、y; in Clause 5, the test piece diameter has been changed from 114 mm to the range of 105 mm to 115 mm and the key 2 in Figure 1 has been changed accordingly; the text in 7.2 has been revised.ISO 5470 consists of the following parts, under the general title Rubber- or plastics-coated fabrics Determin
27、ation of abrasion resistance: Part 1: Taber abrader Part 2: Martindale abraderiv ISO 2016 All rights reservedBS EN ISO 5470-1:2016ISO 5470-1:2016(E)IntroductionIt has long been accepted that some of the parameters associated with the Taber test as given in ISO 5470:1980 needed to be more closely spe
28、cified if reasonable reproducibility (R) was to be obtained. Much of the work is now completed and has been acknowledged by ISO/TC 61 in publishing ISO 9352, which employs a zinc plate as a means of calibrating the initial abrasive power of the wheels. This does not, however, entirely overcome the p
29、roblem of clogging or maintaining abrasion properties between and during tests. It may also be regarded as expensive and time-consuming.This part of ISO 5470 permits the approach in ISO 9352 to be adopted if so desired. However, the major disadvantages of the Taber abrader are that:a) end points can
30、 be somewhat subjective unless a gravimetric technique is employed;b) only a small strip of material is abraded;c) because of the velocity of interfacial friction, localized heating of the coating polymer can cause softening and thus be less representative of abrasive wear in service;d) the 6 mm dia
31、meter hole in the centre of the test piece does not permit post-abrasion assessments of properties such as hydrostatic heat resistance or resistance to chemical reagents.

39、 machine (see Figures 1 and 2), consisting of a housing of compact design, a flat circular turntable designed to carry the test piece, a pair of hinged arms to which abrasive wheels can be attached, a motor for rotating the turntable in the plane of its surface, a counter for indicating the number o
40、f revolutions executed by the turntable, a device enabling the test to be stopped automatically after a predetermined number of revolutions, and a suction attachment for removing debris.The abrasive wheels, which are attached to the free ends of the hinged arms, are free to rotate. Their peripheral
41、surfaces rest on the surface of the test piece. The abrasive wheels are rotated, in opposite directions, by the friction between each wheel and the rotating test piece. At the point of contact between wheel and test piece, the direction of travel of the outer surface of the wheel makes an acute angl
42、e with the direction of travel of the test piece, and this angle extends in opposite directions for each wheel. The position of the abrasive wheels relative to the centre of the turntable is shown in Figure 1 b).The test piece is clamped to the turntable by means of a central threaded rod with a nut
43、 and washer. For measuring thin test pieces the samples can be fixed on a non-flexible supporting cardboard by a double-sided adhesive tape of suitable size. The test piece attached to the cardboard or a solid board equivalent to it can be clamped on the test piece holder of the testing machine and
44、removed easily for weighing. The vertical distance from the centre of the pivot point of the hinged arms to the surface of the turntable is approximately 25 mm.The turntable shall be flat and fixed to the drive shaft. When the turntable is rotated, no point on a 45 mm radius circle traced on its hor
45、izontal surface shall oscillate vertically through more than 0,05 mm about its mean position. The turntable shall have a nominal diameter of 100 mm and its speed of rotation shall be 72 rev/min when a 60 Hz power supply is used and 60 rev/min when a 50 Hz supply is used.The two arms carrying the abr
46、asive wheels shall be symmetrical and able to oscillate freely about a horizontal axis. The method of attaching the wheels, e.g. by means of ball-bearings, shall permit free rotation. In the test position, the mounting bosses shall be co-axial and positioned in such a way that the vertical projectio
47、n of their common axis on to the plane of the turntable is 19,1 mm 0,1 mm from a parallel line passing through the axis of the turntable see Figure 1 a).The distance between the inside face of each abrasive wheel and the centre point shall be 26,2 mm 0,1 mm.Each arm shall be constructed in such a wa
48、y as to permit a counterweight to be fitted to balance the mass of the arm against that of the abrasive wheel and to permit additional weights of known mass to be added (see 4.5).The arms should preferably be designed so that, without any counterweights or additional masses, each would exert a force
49、 of 2,5 N on the test piece.A rotating-turntable twin-wheel abrader of this kind can be used with a test piece of 105 mm to 115 mm in diameter having a central 6 mm diameter hole, thus making available a 54 mm wide test strip, although the wear zone see Figure 1 b) is only approximately 13 mm to 14 mm wide (the width of the wheel plus the effect of the contact angle).2 ISO 2016 All rights reservedBS EN ISO 5470-1:2016ISO 5470-1:2016(E)Dimensions in millimetres12Key1 abrasive wheels2 test piece, diameter 10
