Kunststoffe - Polyamid (PA)-Formmassen - Teil 1: Bezeichnung (ISO 1874-1:1992)

In diesem Teil von ISO 1874 wird ein Bezeichnungssystem für thermoplastische PA-Formmassen festgelegt, das als Grundlage für Spezifikationen dienen kann. Es umfaßt Polyamid Homopolymer-Formmassen auf Basis von PA 6, PA 66, PA 99, PA 610, PA 612, PA 11, PA 12, PA MXD6, PA 46, PA 1212 und Copolymer-Formmassen unterschiedlicher Zusammensetzung.

Plastiques - Matériaux polyamides (PA) pour moulage et extrusion - Partie 1: Désignation (ISO 1874-1:1992)

La présente partie de l'ISO 1874 établit un système de désignation pour les matériaux thermoplastiques polyamides (PA). Ce système peut être utilisé comme base pour les spécifications.  Elle couvre les homopolyamides pour moulage et extrusion basés sur le PA 6, PA 66, PA 69, PA 610, PA 612, PA 11, PA 12, PA MXD6, PA 46, PA 1212, et les copolyamides de compositions diverses pour moulage et extrusion.  Ce système de désignation s'applique à tous les homopolymères et copolymères polyamides. Il s'applique aux matériaux prêts à l'emploi, non modifiés et modifiés par des colorants, des additifs, des charges, des matériaux de renforcement, des modifiants de polymères, etc.  La présente partie de l'ISO 1874 ne s'applique pas aux polyamides de coulée du type PA 6 et PA 12.  Cela ne signifie pas que des matériaux ayant la même désignation présentent nécessairement la même performance. La présente partie de l'ISO 1874 ne comprend pas les données d'ingénierie, les données de performance ou les données sur les conditions de mise en oeuvre pouvant être nécessaires pour spécifier un matériau destiné à une application ou une méthode de mise en ceuvre particulière.  Si de telles propriétés supplémentaires sont nécessaires, elles doivent être déterminées conformément aux méthodes d'essai prescrites dans l'ISO 1874-2, si celles-ci conviennent.  Dans le but de spécifier un matériau thermoplastique pour une application particulière ou une méthode de traitement reproductible, des prescriptions supplémentaires peuvent être codées dans le bloc de données 5 (voir article 3).

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

INTERNATIONAL STANDARD ISO 1874-1 :1992(E)
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 1874 does not provide engineering data, Performance data or data on processing
conditions which may be required to specify a material for a particular application and/or method of processing.
If such additional properties are required, they shall be determined in accordance with the test methods
specified in patt 2 of ISO 1874, if suitable.
1.5 In Order to specify a thermoplastic material for a particular application or reproducible processing, ad-
ditional requirements may be given in Data Block 5 (see clause 3).

3 Designation System
The designation System for thermoplastics is based on the standardized Pattern given in figure 1.
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 four data blocks comprising the following information:
Data Block 1: Identification of the plastic by its Symbol (PA), in accordance with ISO 1043-1, and infor-
mation about Chemical structure and composition (see 3.1).
Data Block 2: Position 1: Intended application or method of processing (see 3.2).
Positions 2 to 8: Important properties, additives and supplementary information (see 3.2).
Designatory properties (see 3.3).
Data Block 3:
Data Block 4: Fillers or reinforcing materials and their nominal content (see 3.4).
For the purpose of specifications, a fifth data block may be added containing additional information. The kind
of information and the code-Ietters used are not the subject of this part of ISO 1874.
The first Character of the Individual Item Block shall be a hyphen.
The four data blocks shall be separated from each other by a comma.
If a data block is not used, this shall be indicated by doubling the Separation sign, i.e. by two commas (,,).
3.1 Data Block 1
In this data block, after the hyphen, the Polyamide plastic is identified using the Symbols and designations Iisted
in tables 1 and 2.
Polyamides containing a plasticizer may be designated by adding the letter P after the Symbol, separated from
it by a hyphen (example: PA SIO-P).
Polyamides containing an impact modifier may be designated by adding the letters Hl after the Symbol, sep-
arated from it by a hyphen (example: PAG-Hl).
