20、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 member body interested in a subject for which a technical committee has been established has the r

21、ight 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 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedur

22、es 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 criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial r

23、ules 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 subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights iden

24、tified 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 name used in this document is information given for the convenience of users and does not constitute an endorsement.For an explanation

26、ble for this document is ISO/TC 45, Rubber and rubber products title, Subcommittee SC 4, Products (other than hoses).This second edition cancels and replaces the first edition (ISO 2286-2:1998), which has been technically revised. The changes are as follows: in 3.1.1, the accuracy of the balance has

27、 been changed; in 3.2, the usable width of the sample has been clearly specified; in 3.3, the drying process has been changed to optional and the conditioning atmosphere has been specified more clearly; in 3.5 and 4.7, item b) has been added; in 4.5.3, the conditioning atmosphere has been specified

28、more clearly.ISO 2286 consists of the following parts, under the general title Rubber or 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, per unit area of coat

30、re quantities which define the basic quality of a coated fabric and determine many of its physical properties. The substrate cloth mass determined by these methods does not necessarily represent the mass of the substrate cloth in the uncoated state. For example, in the case of coated fabrics in whic

31、h a bonding agent has been used, the substrate cloth mass determined may be substantially higher than the uncoated mass because the prescribed treatment has not removed the entire coating. This will be particularly so in cases where the substrate cloth is made from multifilament or spun-fibre yarns.

32、 Dimensional changes in the substrate cloth during processing may also occur.

This International Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of th

Methods for removing coatings of specific compositions are described in Annex A.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references

For undated references, the latest edition of the referenced document (including any amendments) applies.ISO 2231:1989, Rubber- or plastics-coated fabrics Standard atmospheres for conditioning and testing3 Determination of total mass per unit area3.1 Apparatus3.1.1

37、Balance, capable of reading to 1 mg or less.3.1.2 Means of maintaining an atmosphere with a relative humidity not greater than 10 % and a temperature of 65 C 5 C.NOTE Air at 20 C and 65 % relative humidity, when heated at constant pressure to 65 C 5 C, will have a relative humidity of approximately

38、5 %. Higher temperatures can lead to changes in some coatings.3.1.3 Cutter, capable of cutting, from the sample of coated fabric, a test piece of area 100 cm2 1 cm2.NOTE It has been found convenient to use a circular cutter for this purpose, but square or rectangular test pieces can be used provided

39、 they are within the accuracy specified above.INTERNATIONAL STANDARD ISO 2286-2:2016(E) ISO 2016 All rights reserved 1BS EN ISO 2286-2:2016ISO 2286-2:2016(E)3.2 Preparation of test piecesUsing the cutter (3.1.3) cut five test pieces from the sample, from positions spaced reasonably evenly and close

40、to the diagonal across the usable width of the sample excluding 50 mm from the edge of the sample so that the full width of the coated fabric is represented.Do not take any test pieces within 1 m of a production-manufactured roll end.3.3 ProcedureUnless otherwise agreed between the interested partie

41、s to skip the drying process, dry the test pieces to constant mass in an atmosphere with a relative humidity not higher than 10 % at a temperature of 65 C 5 C.Condition the test pieces in accordance with the method of conditioning “1” in ISO 2231:1989 and, without removing them from the conditioning

42、 atmosphere, determine the mass of each to the nearest 5 mg and the surface area of each to within 1 %.NOTE Any estimate of the mass per unit area of the coated fabric derived from the total net mass of the roll and its known length and width may be inaccurate because a complete roll of coated fabri

43、c cannot normally be conditioned to equilibrium in a standard atmosphere. Such inaccuracies are due to excesses or deficiencies in moisture regain through the complete roll.3.4 Calculation and expression of resultsFor each of the five test pieces, calculate the total mass per unit area, M, in grams

44、per square metre, using Formula (1):MmA=104(1)wherem is the mass of the test piece, in grams;A is the area of the test piece, in square centimetres.Calculate the mean of the five determinations, expressing the final result to the nearest 1 g/m2.Take this mean as the total mass per unit area of the m

45、aterial under test.3.5 Test reportThe test report shall include the following information:a) a reference to this part of ISO 2286, i.e. ISO 2286-2;b) the condition at the time of conditioning and the test;c) a complete description of the coated fabric;d) the mean value, in grams per square metre, of

46、 the total mass per unit area obtained from the five test pieces;e) details of any deviations from the procedure specified;f) the date of the determination.2 ISO 2016 All rights reservedBS EN ISO 2286-2:2016ISO 2286-2:2016(E)4 Determination of mass per unit area of substrateCAUTION Some of the solve

47、nts used may be toxic, flammable or otherwise hazardous. Care in the handling of such materials must be exercised. The inhalation of vapours should be avoided. Suitable protective clothing, including gloves and goggles, should be worn when appropriate. It is recommended that a suitable eyewash be ke

48、pt in a position convenient for use. Any further precautionary measures recommended by the solvent manufacturer should be followed.4.1 GeneralThe procedure specified for removing the coating from the substrate cloth is governed both by the nature of the coating and by the nature of the substrate, an

49、d indeed for some types of coating there will be no known method of removal. Where this is the case, it shall be reported in the test report.4.2 PrincipleThe coating is removed with a stripping agent from the same test pieces as were used for the determination of the total mass per unit area. The stripped test pieces are dried, conditioned and weighed. The procedure is repeated until constant mass is reached.4.3 Reagent4.3.1 Suitable solvent system (stripping agent), which has no solvent or chemical action on th
