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. Esch 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, govern-
mental 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.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an Inter-
national Standard requires approval by at least 75 % of the member
bodies casting a vote.
International Standard ISO 1874-1 was prepared by Technical Committee
ISO/TC 61, Plastics, Sub-Committee SC 9, Thermoplastic materials.
This second edition cancels and replaces the first edition
(ISO 1874~1:1985), the scope of which has been extended to include not
only homopolymers but also copolymers.
ISO 1874 consists of the following Parts, under the general title
Plastics - Polyamide (PA) moulding and extrusion materr’als:
- Part 1: Designation
- Part 2: Preparation of fest specimens and determina tion of prop-
erties

Plastics - Polyamide (PA) moulding and extrusion
materials -
Part 1:
Designation
1 Scope
1.1 This part of ISO 1874 establishes a System of designation for Polyamide (PA) thermoplastic materials,
which may be used as the basis for specifications.
lt covers Polyamide homopolymers for moulding and extrusion based on PA 6, PA 66, PA 69, PA 610, PA 612,
PA 11, PA 12, PA MXDG, PA 46, PA 1212 and copolyamides of various compositions for moulding and extrusion.
1.2 The types of Polyamide plastic are differentiated from each other by a classification System based on
appropriate levels of the designatory properties
a) viscosity number,
b) tensile modulus of elasticity and
c) presence of nucleating agent,
and on information about chemical structure, intended application, method of processing, important properties,
additives, colour, fillers and reinforcing materials.
1.3 The designation System is applicable to all Polyamide homopolymers and copolymers. Its applies to ma-
terials ready for normal use, unmodified and modified by colorants, additives, fillers, reinforcing materials,
polymer modifiers, etc.
This patt of ISO 1874 does not apply to monomer casting-type polyamides of PA 6 and PA 12.
1.4 It is not intended to imply that materials having the Same designation give necessarily the Same per-
formante. This part of ISO 187
