BS EN ISO – Thermoplastic elastomers. Nomenclature and abbreviated terms
Endorsement notice The text of ISO We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform the Secretary of the technical committee responsible, the identity of which can be found on the inside front cover.
The main task of 18046 committees is to prepare International Standards.
Amendments issued since publicationThis British Standard was published under the authority Amd. Its aim is both to prevent the occurrence of more than one abbreviated term for a given thermoplastic elastomer term, and to prevent the interpretation of more than one meaning for a given abbreviated term. Some of the terms used to describe the materials lso been used in the literature and in patents. Terminology, Definitions, Identification methods, Plastics and rubber technology, Thermoplastic polymers, Abbreviations, Chemical composition, Polymers, Vocabulary, Classification systems, Symbols, Elastomers.
Users of British Standards should make sure that they possess the latest amendments or editions. Up-to-date lists and bibliographical references concerning such nationalstandards may be obtained on application to the Central Secretariat or to any CEN member. It defines symbols and abbreviated terms used to identify thermoplastic elastomers in industry, commerce and government.
In response to orders for international standards, it is BSI policy to supply the BSI implementation of those that have been published as British Standards, unless otherwise requested. Information regarding online access to British Standards via British Standards Online can be found at http: Styrenic thermoplastic elastomer, consisting of at least a triblock copolymer of styrene and a specific diene, where the two end blocks hard blocks are polystyrene 81064 the internal block soft block or blocks is a polydiene or hydrogenated polydiene.
The system in this International Standard has been devised to avoid any conflict of interests or ambiguity, permit the use of existing terms in the construction of abbreviations for thermoplastic elastomers, and allow for future developments or expansion. Your basket is empty. Various Isp electronic information services are also available which give details on all its products and services.
It is the constant aim of BSI to improve the quality of our products and services. Search all products by.
The thermoplastic and the rubber type shall be listed in decreasing order of abundance in the TPO. This has led to the situation in which nowadays the same material is known under different terms. For details of these and other benefits contact Membership Administration.
A version in any other language made by translationunder the responsibility of a CEN 1864 into its own language and notified to the Central Secretariat has the same status as the officialversions.
In the beginning, different ways were used to describe the representatives of the different classes of these materials. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. The following symbols are used: The work of preparing International Standards is normally carried out through ISO technical committees.
Contact the Information Centre. Commercially available TPV types include: Neither of the existing standards for the nomenclature and abbreviated terms for rubber ISO and for plastics ISO is suitable for is purpose.
This European Standard shall be given the kso of a national standard, either by publication of 1864 identical text or by endorsement, at the latest by Augustand conflicting national standards shall be withdrawn at the latest by August It presents the UK view on standards in Europe and at the international level.
It is not intended to conflict with, but to supplement, existing trade names and trademarks. NOTE 1 The name of the thermoplastic elastomer should be used in technical papers and presentations followed by the abbreviated term used to designate the elastomer in this International Standard.

ISO shall not be held responsible for identifying any or all such patent rights. The BSI copyright iiso displayed in this isk indicates when the document was last issued. You may experience issues viewing this site in Internet Explorer 9, 10 or CopyrightCopyright subsists in all BSI publications.
Reference number ISO It is identical with ISO This does not preclude the free use, in the course of implementing the standard, of necessary details such as symbols, and size, type or grade designations.
Nomenclature and abbreviated terms Status: Worldwide Standards We can source any standard from anywhere in the world. It is, therefore, important that any system of classification and nomenclature for this rapidly expanding polymer sector should be acceptable to both the rubber and plastics industries. The faster, easier way to work with standards. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

Ido order to permit a smooth transition to the newly developed standardized way of describing thermoplastic materials and maintain the link with already existing literature, a number of formerly used terms and abbreviations are given below: RevisionsBritish Standards are updated by amendment or revision.
Compliance with a British Standard does not of itself confer immunity ieo legal obligations. NOTE Thermoplastic rubber is a commonly used term for thermoplastic elastomer.
