This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Augustand conflicting national standards shall be withdrawn at the latest by August Endorsement notice The text of ISO Reference number ISO The work of preparing International Standards is normally carried out through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 right to be represented 180664 that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. The main task of technical committees is to prepare International Standards.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. 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. 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.
Neither of the existing standards for the nomenclature and abbreviated terms for rubber ISO and for plastics ISO is suitable for this 1064.

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. This International Standard uses established abbreviated terms.
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. It defines symbols and abbreviated terms used to identify thermoplastic elastomers in industry, commerce and government.
It is not intended to conflict izo, but to supplement, existing trade names and trademarks. NOTE 1 The name of the io elastomer should be used in technical papers and presentations followed by the abbreviated term used to designate the elastomer in this International Standard. NOTE 2 Annex A gives thermoplastic-elastomer abbreviated terms that have been used in the past in materials standards, technical bulletins, textbooks, patents and trade literature.
Oso dated references, only the edition cited applies. For undated references, the latest edition of the referenced document including any amendments applies. Basic polymers and their special characteristics ISORubber and latices — Nomenclature 3 Generic iwo and definitions 3.
NOTE Thermoplastic rubber is a commonly used lso for thermoplastic elastomer. Styrenic thermoplastic elastomer, consisting of at least a triblock copolymer of styrene and a specific isp, where the two end blocks hard blocks are polystyrene and the internal block soft block or blocks is a polydiene or hydrogenated polydiene.
The following symbols are used: The thermoplastic and the rubber type shall be listed in decreasing order of abundance in the TPO.
ISO – Thermoplastic elastomers — Nomenclature and abbreviated terms
A commercially available TPO type is described as follows: The abbreviation for the rubber shall precede that for the thermoplastic. Commercially available TPV types include: A commercially available TPZ type is described as follows: In the beginning, different ways were used to describe the representatives of the different classes of these materials. Some of the terms used to describe the materials have been used in the literature and in patents.
This has led to the situation in which nowadays the same material is known under different terms. In 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: It presents the UK view on standards in Europe and at the international level.
