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)

Dieses Dokument legt ein Bezeichnungssystem für Polyamid (PA)-Formmassen fest, das als Grundlage für Spezifikationen verwendet werden kann.
Polyamid-Formmasse-Typen werden mit Hilfe eines Einteilungssystems voneinander unterschieden, das auf geeigneten Wertebereichen der kennzeichnenden Eigenschaften
a)   Viskositätszahl,
b)   Zugmodul,
c)   Nukleierungszusatz,
und auf Informationen über die Zusammensetzung, die beabsichtigte Verwendung und/oder dem Verarbeitungsverfahren, wichtigen Eigenschaften, Additiven, Farbmitteln, sowie Füll- und Verstärkungsstoffen beruht.
Das Bezeichnungssystem ist anwendbar auf alle Polyamid-Homopolymere, -Copolymere und -Mischungen.
Es ist anzuwenden für gebrauchsfertige unmodifizierte Materialien und für, beispielsweise durch Farbmittel, Additive, Füllstoffe, Verstärkungsstoffe und Polymermodifikatoren, modifizierte Materialien.
Dieses Dokument ist nicht anzuwenden für die folgenden Werkstoffe:
   monomere Guss-Polyamide von PA 6;
   monomere Guss-Polyamide von PA 12.
Es sollte nicht vorausgesetzt werden, dass Formmassen mit gleicher Bezeichnung auch das gleiche Leistungsverhalten aufweisen. Dieses Dokument enthält keine technischen Daten, Leistungsangaben oder Daten zu Verarbeitungsbedingungen, die erforderlich sein können, um eine Formmasse zu spezifizieren. Wenn derartige ergänzende Eigenschaften erforderlich sind, können sie, soweit möglich, nach den in ISO 16396 2 festgelegten Prüfverfahren bestimmt werden.
Um ein thermoplastisches Material für eine bestimmte Anwendung zu spezifizieren, können im Daten-Block 5 zusätzliche Anforderungen angeführt werden (siehe 4.1).

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.

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 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

4 Designation system
4.1 General
The symbol “%” used in this document means mass fraction.
The designation system for thermoplastics is based on the following standard pattern:
Designation
Description 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.
