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, Part 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, 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. 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.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic
materials.
This first edition of ISO 16396-1 cancels and replaces ISO 1874-1:2010, which has been technically
revised to introduce 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 users 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 — Polymide (PA) moulding and

ISO 16396-1:2015(E)
Introduction
ISO 1874-1:2010 is complex and does not fit with daily practice anymore. In practice, ISO 1043 and
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 products.
INTERNATIONAL STANDARD ISO 16396-1:2015(E)
Plastics — Polyamide (PA) moulding and extrusion
materials —
Part 1:
Designation system, marking of products and basis for
specifications
1 Scope
This part of ISO 16396 establishes a system of designation for polyamide (PA) 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 properties
a) viscosity number and
b) tensile modulus of elasticity
and on information 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 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 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 accordance 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 references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.

3.1 General
The designation system for thermoplastics is based on the following standard pattern:

Figure 1 — Data block designation system
The designation consists of an optional description block, reading “Thermoplastics”, and an identity block
comprising the International Standard number and an individual-item block. For unambiguous designation,
the individual-item block is subdivided into five data blocks comprising the following information.
Data block 1: Position 1: Identification of the plastic by its abbreviated term (PA), in accordance
with ISO 1043-1 and information about the composition of the polymer.
Position 2: Information on the use of plasticizer (P) or impact modifier (I) (see 3.2).
Data block 2: Position 1: Fillers or reinforcements and their nominal content.
Position 2: Flame retardant information.
Position 3: Declaration of recyclate (R) (see 3.3).
Data block 3: Position 1: Intended application and/or method of processing.
Positions 2 to 8: Important properties, additives, and supplementary information
(see 3.4).
Data block 4: Designatory properties (see 3.5).
Data block 5: For the purpose of specification, the fifth data block contains appropriate informa-
tion (see 3.6).
The first character of the individual-item block shall be a hyphen. The data blocks shall be separated
from each other by commas.
If a data block is not used, this shall be indicated by doubling the separation sign, i.e. by two commas („).
Terminal commas can be omitted.
NOTE Data blocks 1 and 2 together form the part marking symbol, connected with a hyphen, and placed
between the punctuation marks ‘>’ and ‘<’, where no spaces are used between the codes.

3.2 Data block 1
In this data block, after the hyphen, the plastic is identified by its abbreviated term (PA) in accordance
with ISO 1043-1 and a symbol indicating the composition as specified in Table 1.
Polyamides containing a plasticizer can be designated by adding the letter P after the symbol, separated
from it by a hyphen (example: PA 610-P).
Polyamides containing an impact modifier can be designated by adding the letter I after the symbol,
separated from it by a hyphen (example: PA 6-I).
Examples of symbols indicating the chemical structure of copolyamide materials are given in Table 2.
