Foreword

ISO (the 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 committee 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 electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, 2 (see www.iso.org/directives ).

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. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

The committee responsible for this document is ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials.

ISO 16365 consists of the following parts, under the general title Plastics — Thermoplastic polyurethanes for moulding and extrusion:

• Part 1: Designation system and basis for specifications
• Part 2: Preparation of test specimens and determination of properties
• Part 3: Distinction between ether and ester polyurethanes by determination of the ester group content

1 Scope

This part of ISO 16365 establishes a system of designation for thermoplastic polyurethane elastomers, which is based on ISO 1043 (all parts) and ISO 11469.

The designation system may be used as the basis for specifications.

The designation system is applicable to all thermoplastic polyurethane elastomers. It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colourants, fillers or other additives, etc.

The types of thermoplastic polyurethane are differentiated from each other by a classification system based on appropriate levels of the designatory properties:

• a) hardness;
• b) tensile modulus of elasticity (optional);

and on information about the alternating hard and soft segments in the main chain, the intended application and/or method of processing, important properties, additives, colour, fillers, and reinforcing materials.

It is not intended to imply that materials having the same designation give necessarily the same performance. This part of ISO 16365 does not provide engineering data, performance data, or data on processing conditions which may be required to specify a material for a particular application and/or method of processing. If such additional properties are required, it is intended that they be determined in accordance with the test methods specified in ISO 16365-2, if suitable.

In order to specify a thermoplastic elastomer for a particular application or reproducible processing, additional requirements are intented to be given in data block 5 (see 3.1 and 3.6).
