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).

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.

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.

materials —
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 properties
a) 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).

3 Designation system
3.1 General

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)
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.

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.
