Plastics - Polyamide (PA) moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties (ISO 1874-2:2012)

This part of ISO 1874 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of polyamide moulding and extrusion materials. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given. Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods that are suitable and necessary to characterize polyamide moulding and extrusion materials are listed. The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use for, or of particular significance to, these moulding and extrusion materials are also included in this part of ISO 1874, as are the designatory properties viscosity number and tensile modulus of elasticity given in ISO 1874-1.

Kunststoffe - Polyamid (PA)-Formmassen für das Spritzgießen und die Extrusion - Teil 2: Herstellung von Probekörpern und Bestimmung von Eigenschaften (ISO 1874-2:2012)

Dieser Teil von ISO 1874 legt die Verfahren zur Herstellung von Probekörpern und die zur Bestimmung der Eigenschaften von Polyamid-Formmassen für das Spritzgießen und die Extrusion anzuwendenden Prüfverfahren fest. Anforderungen an die Behandlung des Prüfmaterials und an das Konditionieren des Prüfmaterials vor dem Formen der Probekörper und der Probekörper vor der Prüfung sind ebenfalls enthalten.
Verfahren und Bedingungen für die Herstellung der Probekörper und Verfahren für die Bestimmung der Eigenschaften der Formmassen, aus denen die Probekörper hergestellt werden, sind angegeben. Eigen-schaften und Prüfverfahren, die anwendbar und notwendig sind, um Polyamid-Formmassen für das Spritzgießen und die Extrusion zu charakterisieren, sind aufgelistet.
Die Eigenschaften wurden aus den allgemein gültigen Prüfverfahren, wie sie in ISO 10350 1 festgelegt sind, ausgewählt. Andere weithin gebräuchliche Prüfverfahren oder solche von besonderer Bedeutung für diese Formmassen, wie die kennzeichnenden Eigenschaften aus ISO 1874 1 (Viskositätszahl und Zug Elastizitäts-modul), sind ebenfalls in diesen Teil von ISO 1874 aufgenommen.

Plastiques - Matériaux polyamides (PA) pour moulage et extrusion - Partie 2: Préparation des éprouvettes et détermination des propriétés (ISO 1874-2:2012)

L'ISO 1874-2:2012 spécifie les méthodes de préparation des éprouvettes et les méthodes d'essai à utiliser pour déterminer les propriétés des matériaux polyamides pour moulage et extrusion. Elle indique les exigences requises lors de la manipulation du matériau d'essai, ainsi que lors de conditionnement dudit matériau avant moulage et des éprouvettes avant l'essai.
Elle précise les modes opératoires et les conditions nécessaires à la préparation des éprouvettes, ainsi que les modes opératoires de mesurage des propriétés des matériaux à partir desquels ces éprouvettes sont fabriquées. Elle fournit également une liste des propriétés et des méthodes d'essai appropriées et nécessaires à la caractérisation des matériaux polyamides pour moulage et extrusion.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 1874-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic
materials.
This fourth edition cancels and replaces the third edition (ISO 1874-2:2006), which has been technically revised.
It also incorporates the Amendment ISO 1874-2:2006/Amd.1:2010.
ISO 1874 consists of the following parts, under the general title Plastics — Polyamide (PA) moulding and
extrusion materials:

Part 2:
Preparation of test specimens and determination of properties
1 Scope
This part of ISO 1874 specifies the methods of preparation of test specimens and the test methods to be used
in determining the properties of polyamide moulding and extrusion materials. Requirements for handling test
material and for conditioning both the test material before moulding and the specimens before testing are given.
Procedures and conditions for the preparation of test specimens and procedures for measuring properties of
the materials from which these specimens are made are given. Properties and test methods that are suitable
and necessary to characterize polyamide moulding and extrusion materials are listed.
The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide
use for, or of particular significance to, these moulding and extrusion materials are also included in this part of
ISO 1874, as are the designatory properties viscosity number and tensile modulus of elasticity given in ISO 1874-1.
