23、, (c) BSI EN ISO 2286-3:1998 ii BSI 04-1999 Foreword 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. Each membe
24、r 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 International Elec
25、trotechnical Commission (IEC) on all matters of electrotechnical standardization. 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
26、 a vote. International Standard ISO 2286-3 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products. Together with the other parts (see below), it cancels and replaces ISO 2286:1986, which has been technically revised. ISO 2286 consists of the following parts, under the general titl
27、e Rubber- and plastics-coated fabrics Determination of roll characteristics: Part 1: Methods for determination of length, width and net mass; Part 2: Methods for determination of total mass per unit area, mass per unit area of coating and mass per unit area of substrate; Part 3: Method for determina
28、tion of thickness. Descriptors: Fabrics, woven fabrics, coated fabrics, fabrics coated with rubber, fabrics coated with plastics, rolls, tests, determination, thickness, dimensional measurements.

29、SI EN ISO 2286-3:1998 BSI 04-19991 Introduction Compared with metals, coated fabrics are easily compressed, and the measured thickness will depend considerably upon the method and pressure employed. This is perhaps the single most important reason for having a standard method for measuring the thick
30、ness of coated fabrics. An effort has been made to enable the results to be comparable with measurements of the thickness of textile substrates. WARNING Persons using this part of ISO 2286 should be familiar with normal laboratory practice. This part of ISO 2286 does not purport to address all of th
31、e safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. 1 Scope This part of ISO 2286 describes a method for the determination, at a specified press
32、ure, of the thickness of rubber- and plastics-coated fabrics, irrespective of the type of substrate employed. It is applicable to single-face, double-face and double-texture coated fabrics, as well as materials in which an expanded layer is included in the coating. 2 Normative reference The followin
33、g standard contains provisions which, through reference in this text, constitute provisions of this part of ISO 2286. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this this part of ISO 2286 are encouraged to in
34、vestigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 2231:1989, Rubber- or plastics-coated fabrics Standard atmospheres for conditioning and testing. 3 Definitions For
35、the purposes of this part of ISO 2286, the following definitions apply. 3.1 thickness the distance between the face and the back of a coated fabric, measured as the vertical distance between a reference plate on which the fabric rests and a parallel presser foot that is applying a pressure to the fa
36、bric NOTEFor convenience, the reference plate on which the fabric rests is referred to as the anvil. 3.2 usable width that width of a coated fabric, excluding the selvedge, which is consistent in its properties, uniformly finished and free from unacceptable flaws 4 Apparatus 4.1 Dial gauge, of the d
37、eadweight type, designed to register the vertical distance between the bearing surfaces of a presser foot and reference plate, and equipped with a dial graduated to give a direct readout of the thickness to the nearest 0,02 mm. The gauge shall be calibrated in such a way as to permit at least one of
38、 the pressures specified in 4.2 to be obtained using at least one of the presser foot sizes. 4.2 Circular presser foot, with a smooth, flat surface and a diameter of not less than 9 mm, capable of applying one or more of the following pressures: a) 2 kPa 0,2 kPa; b) 10 kPa 1,0 kPa; c) 24 kPa 2,4 kPa
39、. NOTE 12 kPa is the recommended pressure. NOTE 2The actual pressure exerted by the presser foot may be calculated in one of the following ways: a) by determining 1) the force exerted by the presser foot assembly, using a calibrated counterbalance and 2) the surface area of the presser foot by direc
40、t measurement or b) by using a tension dial gauge. 4.3 Reference plate (anvil), having a plane upper surface of diameter at least 50 mm greater than that of the presser foot. 4.4 Means for moving the presser foot in a direction normal to the upper surface of the reference plate so that its bearing s
41、urface is maintained parallel to the upper surface of the reference plate. NOTEThe parallelism of the presser foot and anvil surfaces when brought together can conveniently be checked by inserting a feeler gauge (one only, not several together) at points round the edge of the presser foot while it i
42、s resting freely on the anvil. 5 Conditioning Condition the fabric to be tested in accordance with ISO 2231.

43、rfaces of the presser foot and anvil and adjust the dial gauge to register zero when the anvil and presser foot are in contact. Make ten thickness measurements, evenly spaced across the usable width of the fabric, as follows: Place the fabric on the anvil, ensuring that the fabric is smooth, without
44、 any accidental creases or wrinkles and without any tension. If there are intentional creases in the fabric, no attempt shall be made to smooth them out before making measurements. Lower the presser foot gently on to the fabric and allow it to rest on the fabric for 10 s. (For highly compressible ma
45、terials, a 30 s time interval may be needed. This shall be reported in the test report.) Record the dial gauge reading to the nearest 0,02 mm. If the fabric has an embossed surface, do not avoid the areas of embossing. Do not make any measurements within 1 m of a production-manufactured roll end. 7
46、Expression of results Calculate the arithmetic mean, in millimetres, of the ten determinations. Take this mean as the thickness of the coated fabric. 8 Test report The test report shall include the following information: a) a reference to this part of ISO 2286; b) a complete description of the coate
47、d fabric; c) the mean, minimum and maximum thicknesses, in millimetres, of the coated fabric, the pressure at which the measurements were made, the diameter of the presser foot used and the length of time the presser foot was allowed to rest on the fabric; d) details of any deviations from the proce
48、dure specified; e) the date of the determination.
