This British Standard is published under the direction of the Sector Board for Materials and Chemicals whose Technical Committee PRI/10 has the responsibility to: aid enquirers to understand the text; present to the

12、he 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 member body interested in a subject for which a technical commit
13、tee 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 Electrotechnical Commission (IEC) on all matters of electrotech
14、nical 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 a vote. International Standard ISO 1629 was prepared by Te
15、chnical Committee ISO/TC 45, Rubber and rubber products. This third edition cancels and replaces the second edition (ISO 1629:1987), which has been technically revised.

16、+00:00 2006, Uncontrolled Copy, (c) BSI BS ISO 1629:1995 BSI 02-19991 1 Scope 1.1 This International Standard establishes a system of symbols for the basic rubbers in both dry and latex forms, based on the chemical composition of the polymer chain. 1.2 The purpose of this International Standard is t
17、o standardize the terms used in industry, commerce and government, and it is not intended to conflict with, but rather to act as a supplement to, existing trade names and trade marks. NOTE 1In technical papers or presentations, the name of the rubber should be used if possible. The symbols should fo
18、llow the chemical name for use in later references. 2 Rubbers Rubbers, in both dry and latex forms, are grouped and symbolized on the basis of the chemical composition of the polymer chain in the following manner: 3 Symbol groups 3.1 The “M” group The “M” group comprises rubbers having a saturated c
19、hain of the polymethylene type. The following symbols are used: 3.2 The “O” group The “O” group comprises rubbers having carbon and oxygen in the polymer chain. The following symbols are used: MRubbers having a saturated carbon chain of the polymethylene type NRubbers having carbon and nitrogen in t
20、he polymer chain NOTE 2No rubber has so far been symbolized in the “N” group. ORubbers having carbon and oxygen in the polymer chain QRubbers having silicon and oxygen in the polymer chain RRubbers having an unsaturated carbon chain, e.g. natural rubber and synthetic rubbers derived at least partly
