BS 903-0:2012 pdf free.Physical testing of rubber General.
BS 903-0 This part of BS 903 provides a general introduction to BS 903 and to BS ISO standards. 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 British Standards is also provided.NOTE The status of methods referenced need to 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.Terms and definitions For the purposes of this part of BS 903, the terms and definitions given in BS ISO 1382 apply.Normative reference The following documents, in whole or in part, are normatively referenced in this
document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.BS ISO 1382, Glossary of rubber terms.The individual test methods published in BS 903 and as BS ISO standards are listed in Annex A. The methods fall into eight main categories:1) tests for raw and unvulcanized rubber;2) preparative procedures;3) mechanical tests;4) viscoelastic tests;5) degradation and environmental tests; 6) tests on effect of fluids
7) adhesion and contact property tests; and 8) electrical tests.NOTE The prefix“BS 903”applies to the referenced standards unless otherwise indicated. In terms of these categories, the standards may be grouped as in Table 1 to Table 8, although there is some overlap.For the testing of rubber, the use of BS 903 and BS ISO test methods 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 samples or test sheets or from finished rubber products. In most instances, these test pieces are cut by dies or knives from a representative sample.In these cases attention is drawn to the procedures specified in BS ISO 23529 as
the method of preparation can affect test performance, especially where strength measurements are involved. For some tests, directly moulded test pieces are necessary or most appropriate.
