The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which a technical committee has been established hasthe right to be represented on that committee. International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (IEC) on all matters of electrotechnical standardization.International Standards are drafted 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.International Standard ISO 5470-1 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products.It cancels and replaces ISO 5470:1980, which has been technically revised.ISO 5470 consists of the following parts, under the general title Rubber- or plastics-coated fabrics — Determinationof abrasion resistance:¾ Part 1: Taber abrader¾ Part 2: Martindale abraderAnnex A forms an integral part of this part of ISO 5470.SIST EN ISO 5470-1:1999
© ISOISO 5470-1:1999(E)iiiIntroductionIt has long been accepted that some of the parameters associated with the Taber test as given in ISO 5470:1980needed to be more closely specified if reasonable reproducibility (R) was to be obtained. Much of the work is nowcompleted and has been acknowledged by ISO/TC 61 in publishing ISO 9352, which employs a zinc plate as ameans of calibrating the initial abrasive power of the wheels. This does not, however, entirely overcome the problemof clogging or maintaining abrasion properties between and during tests. It may also be regarded as expensive andtime-consuming.This part of ISO 5470 permits the approach in ISO 9352 to be adopted if so desired. However, the majordisadvantages of the Taber abrader are that:a) end points can 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 andthus be less representative of abrasive wear in service;d) the 6 mm diameter hole in the centre of the test piece does not permit post-abrasion assessments of propertiessuch as hydrostatic heat resistance or resistance to chemical reagents.SIST EN ISO 5470-1:1999

Abrasion test machine (see Figures 1 and 2), consisting of a housing of compact design, a flat circularturntable designed to carry the test piece, a pair of hinged arms to which abrasive wheels can be attached, a motorfor rotating the turntable in the plane of its surface, a counter for indicating the number of revolutions executed bythe 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 peripheralsurfaces rest on the surface of the test piece. The abrasive wheels are rotated, in opposite directions, by the frictionbetween each wheel and the rotating test piece. At the point of contact between wheel and test piece, the directionof travel of the outer surface of the wheel makes an acute angle with the direction of travel of the test piece, and thisangle extends in opposite directions for each wheel. The position of the abrasive wheels relative to the centre of theturntable is shown in Figure 1.The test piece is clamped to the turntable by means of a central threaded rod with a nut and washer. When testingthin test pieces, a ring clamp or double-sided adhesive tape is used to hold the test piece firmly on the turntable.The vertical distance from the centre of the pivot point of the hinged arms to the surface of the turntable isapproximately 25 mm.The turntable shall be flat and fixed to the drive shaft. When the turntable is rotated, no point on a 45 mm radiuscircle traced on its horizontal 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 Hzpower supply is used and 60 rev/min when a 50 Hz supply is used.The two arms carrying the abrasive 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 projection of their common axison 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).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 way as to permit a counterweight to be fitted to balance the mass of thearm against that of the abrasive wheel and to permit additional weights of known mass to be added (see 4.5).NOTE 1The arms should preferably be designed so that, without any counterweights or additional masses, each wouldexert a force of 2,5 N on the test piece.NOTE 2A rotating-turntable twin-wheel abrader of this kind can be used with a test piece approximately 114 mm in diameterhaving a central 6 mm diameter hole, thus making available a 54 mm wide test strip, although th
