Plastics - Polyamide (PA) moulding and extrusion materials - Part 1: Designation system and basis for specifications (ISO 16396-1:2022)
This document 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,
b) tensile modulus, and
c) nucleating additive,
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 is applicable to unmodified materials ready for normal use and materials modified, for example, by
colorants, additives, fillers, reinforcing materials, and polymer modifiers.
This document does not apply to the following materials:
— monomer casting-type polyamides of PA 6;
— monomer casting-type polyamides of PA 12.
It is not intended to imply that materials having the same designation give the same performance.
This document 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 can be
determined according to the test methods specified in ISO 16396-2, if suitable.
In order to specify a thermoplastic material for a particular application, additional requirements can be
given in data block 5 (see 4.1).
Kunststoffe - Polyamid (PA)-Formmassen für das Spritzgießen und die Extrusion - Teil 1: Bezeichnungssystem und Basis für Spezifikationen (ISO 16396-1:2022)
Dieser Teil von ISO 16396 legt ein Bezeichnungssystem für Polyamid (PA)-Formmassen fest, das als Grundlage für Spezifikationen angewendet werden kann.
Polyamid-Formmasse-Typen werden mit Hilfe eines Einteilungssystems voneinander unterschieden, das auf geeigneten Wertebereichen der kennzeichnenden Eigenschaften:
a) Viskositätszahl und
b) Zugelastizitätsmodul
c) Nukleierungsmittel
und Informationen über Zusammensetzung, Verwendungszweck und/oder Verarbeitungsverfahren, wichtige Eigenschaften, Additive, Farbmittel, Füll- und Verstärkungsstoffe beruht.
Das Bezeichnungssystem ist anwendbar auf alle Polyamid-Homopolymere, -Copolymere und -Mischungen.
Es gilt für gebrauchsfertige Formmassen, nicht modifiziert oder modifiziert mit Farbmitteln, Additiven, Füllstoffen, Verstärkungsstoffen, Polymermodifikatoren.
Dieser Teil von ISO 16396 ist nicht anwendbar auf die folgenden Werkstoffe:
a) monomere Guss-Polyamide von PA 6;
b) monomere Guss-Polyamide von PA 12.
Es sollte nicht unterstellt werden, dass Formmassen mit gleicher Bezeichnung auch das gleiche Leistungsverhalten aufweisen. Dieser Teil von ISO 16396 enthält keine technischen Daten, Leistungsangaben oder Daten zu Verarbeitungsbedingungen, die erforderlich sein können, um eine Formmasse zu spezifizieren. Wenn derartige zusätzliche Eigenschaften erforderlich sind, müssen sie, soweit möglich, nach den in ISO 16396-2 festgelegten Prüfverfahren bestimmt werden.
Um eine thermoplastische Formmasse für eine bestimmte Anwendung oder reproduzierbare Verarbeitung zu spezifizieren, müssen zusätzliche Anforderungen im Daten-Block 5 angeführt werden (siehe 3.1).
Plastiques - Matériaux à base de polyamide (PA) pour moulage et extrusion - Partie 1: Système de désignation et base de spécifications (ISO 16396-1:2022)
Le présent document établit un système de désignation des matériaux à base de polyamide (PA) pour moulage et extrusion, qui peut être utilisé comme base pour les spécifications.
Les types de plastiques polyamides sont différenciés les uns des autres par un système de classification fondé sur des niveaux appropriés des propriétés de désignation:
a) indice de viscosité,
b) module en traction, et
c) additifs de nucléation,
et sur des informations concernant la composition, l’application prévue et/ou la méthode de mise en œuvre, les propriétés importantes, les additifs, les colorants, les charges et les matériaux de renfort.
Le système de désignation est applicable à tous les homopolymères, copolymères et mélanges polyamides.
Il est applicable aux matériaux non modifiés prêts à l’emploi normal et aux matériaux modifiés, par exemple par des colorants, des additifs, des charges, des matériaux de renfort, ainsi qu’aux modificateurs de polymères.
Le présent document ne s’applique pas aux matériaux suivants:
— les polyamides de type coulée monomères de PA 6;
— les polyamides de type coulée monomères de PA 12.
Le fait que des matériaux aient la même désignation n’implique pas qu’ils présentent les mêmes performances. Le présent document ne comporte pas de données sur la conception, les performances ou les conditions de mise en œuvre qui peuvent être exigées pour spécifier un matériau. Si de telles caractéristiques supplémentaires sont nécessaires, elles peuvent être déterminées conformément aux méthodes d’essai spécifiées dans l’ISO 16396‑2, s’il y a lieu.
Afin de spécifier un matériau thermoplastique pour une application particulière, les exigences additionnelles peuvent être codées dans le bloc de données 5 (voir 4.1).

Introduction
In practice, ISO 1043 and ISO 11469 are, in combination, being "improperly" used as a designation
system for, e.g. marking. The aim of this document 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.© ISO 2022 – All rights reserved

Part 1:
Designation system and basis for specifications
1 Scope
This document 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 propertiesa) viscosity number,
b) tensile modulus, and
c) nucleating additive,
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 is applicable to unmodified materials ready for normal use and materials modified, for example, by
colorants, additives, fillers, reinforcing materials, and polymer modifiers.This document does not apply to the following materials:
— monomer casting-type polyamides of PA 6;
— monomer casting-type polyamides of PA 12.
It is not intended to imply that materials having the same designation give the same performance.
This document 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 can be
determined according to the test methods specified in ISO 16396-2, if suitable.In order to specify a thermoplastic material for a particular application, additional requirements can be
given in data block 5 (see 4.1).2 Normative references

4.1 General
The symbol “%” used in this document means mass fraction.
The designation system for thermoplastics is based on the following standard pattern:
DesignationDescription block Identity block
Thermoplastics Individual-item Block
International
Standard Block
Data block 1 Data block 2 Data block 3 Data block 4 Data block 5
(optional)
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 4.2).
Data block 2: Position 1: Fillers or reinforcements and their nominal content.Position 2: Flame retardant information.
Position 3: Declaration of recyclate (R) (see 4.3).
Data block 3: Position 1: Intended application and/or method of processing. Positions 2 to 8: Im-
portant properties, additives, and supplementary information (see 4.4).Data block 4: Designatory properties (see 4.5).
Data block 5: For the purpose of specification, the fifth data block contains appropriate informa-
tion (see 4.6).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.

4.3 Data block 2
In this data block, the type of filler and/or reinforcing material is represented by a single code letter
in position 1, and its physical form by a second code letter in position 2, where the code letters are as
specified in Table 3. Subsequently (without a space), the actual content by mass percent can be given by
a two figure number in position 3.Mixtures of filler materials or forms can be indicated by combining the relevant codes using the sign“+”
and placing the whole between parenthesis or by combining the relevant codes using the sign “+” and
placing the whole between parentheses followed by the total filler content. For example, a mixture of
25 % glass fibre (GF) and 10 % mineral powder (MD) would be indicated by (GF25+MD10) or (GF+MD)35.
For marking purposes, combining the relevant codes followed by the total filler content outside the
parentheses is preferred.Table 3 — Coding system for fillers and reinforcing materials in data block 2

Metal filler shall be identified by the chemical symbol (in capital letters) after the mass content. For example, iron
whiskers can be designated “MEH05FE”.Separated from the reinforcement code by a space, the addition of a flame retardant or flame retardant
behaviour is represented by the abbreviated term “FR” followed, without a space, by a two digit code
number between parentheses of the flame retardant type according ISO 1043-4.Separated by a space from the flame retardant or the reinforcement code if no flame retardant code is
used, the declaration of recyclate is represented by the code R between parentheses (R). Following the
code R, the mass content can be given between the parentheses without a space. For example, a PA 66
containing 20 % glass fibre based upon a resin composed nominally of 70 % recyclate and 30 % virgin
material will be indicated ISO 16396-PA 66,GF20 (R70).4.4 Data block 3

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

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.

Part 1:
Designation system 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 propertiesa) viscosity number and
b) tensile modulus of elasticity
c) nucleating additive
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 16396-2, 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 are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

3 Designation system
3.1 General
The designation system for thermoplastics is based on the following standard pattern:
DesignationDescription block Identity block
Thermoplastics Individual-item Block
International
Standard Block
Data block 1 Data block 2 Data block 3 Data block 4 Data block 5
(optional)
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 SO 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 infor-
mation (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 1 to entry 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.

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.
