7、s withdrawn. BS 903 is the best-known British Standard for rubber and was first published as a compilation of test methods in 1940. It quickly developed an international reputation, especially in the Commonwealth and parts of Europe, and many of its methods were subsequently adopted as international
8、 (ISO) standards. BS 903 is split into two series. Series A comprises the general methods of test A1A65. Series C comprises the methods of test C1C5, used to determine the electrical properties of vulcanized rubber. The work of Subcommittee ISO/TC 45/SC2, Rubber and rubber products Testing and analy
9、ses, continues in reviewing and revising international standards and in developing new test methods and guides to keep abreast of changes and developments in technology, and in this the UK plays a leading and active role. As a consequence, the status of methods is continually changing, as new editio
10、ns are published and new methods appear. It is therefore never possible for this Part of BS 903 to be completely up-to-date and this present edition is therefore only a snapshot in time. The purpose of this part is to provide a general introduction to the range of British and international Standard
11、test methods used to determine the physical properties of rubber. (The methods embrace raw, unvulcanized, vulcanized and thermoplastic rubbers.) A detailed and comprehensive cross-reference is given in Annex A of corresponding international standards; Annex B gives a list of those international stan
12、dards issued by ISO/TC 45/SC2; and Annex C provides recommendations for the rounding-off of test results. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard does not of itself
13、confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 19 and a back cover.

14、cope This part of this British Standard provides a general introduction to BS 903 and to BS ISO standards in the BS 903 series. It describes a range of laboratory-scale methods for the physical testing of rubber in raw, unvulcanized, vulcanized and thermoplastic forms. A list of closely-related Brit
15、ish Standards is also provided. NOTEThe status of methods referenced here should be verified with the relevant standards body; they are continually changing as new editions are issued and new methods appear, in line with developments in technology. 2 Terms and definitions For the purposes of this Br
16、itish Standard, the terms and definitions given in BS 3558 apply. 3 Normative reference BS 3558 (all parts), Glossary of rubber terms. 4 Reproducibility A number of the test methods include a statement on test precision as determined by an interlaboratory test programme and ISO/TC 45 intends that th
17、is should eventually be extended to all methods. Attention is drawn to ISO/TR 9272 and ISO/TR 11753. 5 Test method categories and properties 5.1 General The individual test methods published in the A series of BS 903 and as BS ISO standards are listed in Annex A. Most of the BS 903 A series test met
18、hods are identical with those standardized by Technical Committee ISO/TC 45, Rubber and rubber products, of the International Organization for Standardization (ISO) and, where this is so, the methods have been published as dual-numbered British Standards, although current practice is now to adopt IS
19、O standards as BS ISO standards with the same ISO numbers. In all cases the ISO equivalents are also listed. Additional methods are in preparation. Annex B gives a full list of those international standards issued by ISO/TC 45/SC2. The methods fall into seven main categories: a) tests for unvulcaniz
20、ed rubber; b) preparative procedures; c) mechanical tests; d) viscoelastic tests; e) degradation and environmental tests; f) tests on effect of fluids; g) adhesion and contact property tests. In terms of these categories the existing parts of BS 903 and BS ISO standards can be grouped as in 5.2 to 5
21、.8, although there will be some overlap. NOTEThe prefix BS 903 applies to the referenced standards unless otherwise indicated.

40、ge 6.1 Application For the testing of rubber the use of BS 903 and BS ISO test methods from the BS 903 series should always be considered before resorting to other methods or procedures. These methods are intended for use with small, laboratory test pieces taken either from specially prepared sample
41、s or test sheets or from finished rubber products. In most instances these test pieces will be cut by dies or knives from a representative sample and here, attention is drawn to the procedures specified in BS 903-A36, since the method of preparation can affect test performance, especially where stre
42、ngth measurements are involved. For some tests, directly moulded test pieces are necessary or most appropriate. The BS 903 series test methods, including the BS ISO methods listed in this part of BS 903, are applicable to unvulcanized and vulcanized rubber prepared from dry rubber or latex. Most, al
43、though not all, of the test methods described for vulcanized rubber are suitable for use with thermoplastic rubbers and their products. The scopes of many of the test methods have already been extended to include thermoplastic rubbers. The BS 903 series test methods, including the BS ISO methods lis
44、ted in this part of BS 903, are not intended for use with cellular rubber or with rubber-coated fabrics except where specified, although several standards can be applied to some cellular rubber materials and products. Dedicated test methods for flexible cellular materials are given in BS 4443, whils
45、t dedicated methods for coated fabrics are given in BS 3424. 6.2 Selection of test method Detailed guidance on the selection and use of laboratory-scale tests is given in BS 903-1. Many of the methods give options for test piece size and shape, test procedure, test environment and, where appropriate
46、, test duration. For example, heat ageing tests conducted in accordance with BS 903-A19 may be carried out at one or more of several standard or recommended test temperatures and times. Such options should be selected to suit the particular application and in all cases the conditions used should be
47、specified and reported. Considerations will include the size of sample or product, the overall test time, the anticipated service environment and for example whether or not the test is for quality control or type approval purposes. peel testA21.1:1997 (N ISO 813:1997) two-plate methodA21.2:1997 (N I
