19、3iiiISO 5470-2:2003(E) vi I SO 3002 All irhgts seredevrForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees.
20、 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 collaborates closely with the Interna
21、tional Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Stan
22、dards 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. Attention is drawn to the possibility that some of the elements of this document may be the subje
23、ct of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 5470-2 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 4, Products (other than hoses). ISO 5470 consists of the following parts, under the general titl
24、e Rubber- or plastics-coated fabrics Determination of abrasion resistance: Part 1: Taber abrader Part 2: Martindale abrader ENISO54702:2003ivINTENRATIONAL TSANDADR IS-0745 O2:(3002)EI SO 3002 All irhgts seredevr 1Rubber- or plastics-coated fabrics Determination of abrasion resistance Part 2: Martind
25、ale abrader WARNING Persons using this part of ISO 5470 should be familiar with normal laboratory practice. This part of ISO 5470 does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health p
26、ractices and to ensure compliance with any regulatory conditions. 1 Scope This part of ISO 5470 details two separate methods for determining the resistance of a material to wet and dry abrasion. It is applicable to the coated surface or surfaces of coated fabrics. If the abrasion behaviour of the un
27、coated surface of a coated fabric is to be determined, use the methods for uncoated textiles described in the various parts of ISO 12947. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited app
28、lies. For undated references, the latest edition of the referenced document (including any amendments) applies.

In method 1, test specimens are clampe
31、d in a specimen holder and abraded using pieces of a selected abradant under constant pressure. A variant of this method consists of carrying out the method with a wet abradant. Method 2 reverses the position of the abradant and the specimen. In both cases, the relative movement between the abradant
32、 and the specimens forms a complex cyclic pattern (a Lissajous figure) which produces rubbing in all directions. The test is stopped either after a predetermined number of cycles (in which case the damage to each specimen is assessed) or when the specimen has reached a predetermined degree of abrasi
33、on (in which case the number of cycles is noted). ENISO54702:20031ISO 5470-2:2003(E) 2 I SO 3002 All irhgts seredevr4 Apparatus and materials 4.1 Abrasion machine, with one or more test stations, each fitted with the items of equipment specified in 4.1.1 to 4.1.6. 4.1.1 Circular specimen holder, wit
34、h a clamping ring which grips the specimen around its edge, leaving an exposed raised flat circular portion of area (645 5) mm 2 . 4.1.2 Horizontal abradant table, of sufficient size to incorporate a square central test area of side 88 mm. Typically, abradant tables are circular and have a diameter
35、of at least 125 mm. 4.1.3 Means of holding the exposed flat portion of the specimen holder (4.1.1) in contact with the abradant table (4.1.2) whilst allowing the specimen holder to rotate freely in the plane of the abradant table. 4.1.4 Means of producing relative movement between the specimen holde
36、r (4.1.1) and the abradant table (4.1.2) which forms a Lissajous figure occupying an area of (60 1) mm (60 1) mm (see Figure 1). Each Lissajous figure requires 16 elliptical motions (revolutions) of the specimen holder, and the speed of operation of the tester shall be (48 4) revs/min. The paralleli
37、sm of the abradant table (4.1.2) and the specimen holder (4.1.1) shall be maintained to within 0,05 mm throughout each Lissajous figure. A dial gauge fitted in place of the specimen holder can be used to verify the parallelism of the abradant table. The circumferential parallelism of the holder (4.1
38、.1) in contact with the abradant table shall be better than 0,05 mm. This can be verified by attempting to insert slip gauges of thickness less than 0,05 mm under the edges of the flat face of the specimen holder. 4.1.5 Means of maintaining a constant pressure of (12 0,2) kPa between the specimen ho
39、lder (4.1.1) and the abradant table (4.1.2). This will be the case if the mass of the specimen holder and its associated fittings is (795 5) g. 4.1.6 Means of counting the number of abrasion cycles completed in terms of revolutions (16 revs per cycle). 4.2 Reference abradant 4.2.1 General Unless oth
40、erwise stated by mutual agreement between the interested parties, this shall be either a wool abradant fabric or a silicon carbide cloth. Results from tests carried out with different abradants are not considered to be comparable. When tests are carried out, by mutual agreement of all parties, using
41、 a non- standard abradant, a description of this abradant shall be included in the test report. 4.2.2 Wool abradant fabric The properties of wool abradant fabric shall be as given in Table 1.

This is normally the slightly smoother face of the fabric. Stocks of the fabric shall be controlled to ensure that only this face is used i

The weightpiece shall apply a pressure of (2 0,2) kPa. 4.4 Cutti
46、ng device, such as a die cutter, of sufficient size to produce specimens that will be held firmly in the specimen holders (4.1.1). The exact size of the device will depend on the design of the clamping system of the specimen holder. 4.5 Four pieces of wool felt, mass per unit area 575 gm 2to 800 gm
47、2 , and thickness 2,0 mm to 3,5 mm. Both sides of the felt may be used. The felt used in dry tests may be re-used either until both sides are discoloured or until the thickness has been reduced to less than 2,0 mm, but felt used in wet tests shall not be re-used. 4.6 Polyurethane foam, of thickness (3 1) mm, density (30 2) kgm 3and indentation hardness (5,8 0,8) kPa. 4.7 Water-jet: a rubber tube with one end restricted and the other attached to a cold-water tap at mains pressure is suitable.
