The work of preparing International Standards is normally carried out through ISO technical
19、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
20、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, Part 1. In particular the different approval criteria needed for
21、 the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 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.
22、 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).

25、a new designation system.The revised designation system is published under a new ISO number, as many existing documents refer to ISO 1874-1. If the existing ISO 1874-1 would be replaced by the new designation system, these documents would refer to the incorrect designation system.In order to give us
26、ers time to switch from ISO 1874-1 to ISO 16396-1, any designation system according to ISO 1874-1 is to be phased out in 5 to 10 years. During this period, ISO 1874-2 will effectively be Part 2 of this International Standard.ISO 16396 consists of the following parts, under the general Plastics Polym

In practice, ISO 1043 and
28、 ISO 11469 are, in combination, improperly being used as a designation system for, e.g. marking. The aim of this International Standard is to simplify the data block system and to connect more to ISO 1043 and ISO 11469, where the first two blocks are used for generic identification and marking of pr

30、moulding and extrusion materials, which can be used as the basis for specifications.The types of polyamide plastics are differentiated from each other by a classification system based on appropriate levels of the designatory propertiesa) viscosity number andb) tensile modulus of elasticityand on inf
31、ormation about composition, intended application and/or method of processing, important properties, additives, colorants, fillers, and reinforcing materials.The designation system is applicable to all polyamide homopolymers, copolymers, and blends.It applies to unmodified materials ready for normal
32、use and materials modified, for example, by colorants, additives, fillers, reinforcing materials, and polymer modifiers.This part of ISO 16396 does not apply to the following materials:a) monomer casting-type polyamides of PA 6;b) monomer casting-type polyamides of PA 12.It is not intended to imply
33、that materials having the same designation give the same performance. This part of ISO 16396 does not provide engineering data, performance data, or data on processing conditions which can be required to specify a material. If such additional properties are required, they will be determined in accor
34、dance with the test methods specified in ISO 1874-2, if suitable.In order to designate a thermoplastic material to meet particular specifications, the requirements are to be given in data block 5 (see 3.1).2 Normative referencesThe following documents, in whole or in part, are normatively referenced
