Plastics - Polyoxymethylene (POM) moulding and extrusion materials - Part 1: Designation system and basis for specifications (ISO 9988-1:2004)
This part of ISO 9988 establishes a system of designation for polyoxymethylene (POM) thermoplastic materials, which may be used as the basis for specifications. Polyoxymethylene materials are thermoplastic materials composed principally of long-chain synthetic homopolymers and copolymers of formaldehyde. The repeating unit in the molecular chain is - CH2O - as an integral part of the main polymer chain resulting from polymerization of formaldehyde. The types of polyoxymethylene plastic are differentiated from each other by a classification system based on appropriate levels of the following designatory properties: a) melt mass-flow rate or melt volume-flow rate, b) tensile modulus, and on information about basic polymer parameters, intended application, method of processing, important properties, additives, colorants, fillers and reinforcing materials. This part of ISO 9988 is applicable to all polyoxymethylene homopolymers and to copolymers of polyoxymethylene and blends of polymers containing polyoxymethylene. It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified and modified by colorants, additives, fillers, etc. It is not intended to imply that materials having the same designation necessarily give the same performance. This part of ISO 9988 does not provide engineering data, performance data or data on processing conditions which may be required to specify materials for particular end-use applications. If such additional properties are required, they shall be determined in accordance with the test methods specified in part 2 of this International Standard. In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see 3.1).
Kunststoffe - Polyoxymethylen (POM)-Formmassen - Teil 1: Bezeichnungssystem und Basis für Spezifikationen (ISO 9988-1:2004)
1.1 In diesem Teil von ISO 9988 wird ein Bezeichnungssystem für Thermoplaste aus Polyoxymethylen
(POM) festgelegt, das als Grundlage für Spezifikationen dienen kann.
Polyoxymethylen-Materialien sind Thermoplaste, die hauptsächlich aus langkettigen synthetischen Homopoly-meren
und Copolymeren von Formaldehyd bestehen. Die sich wiederholende Einheit in der
Molekülkette - CH 2 O - ist ein integraler Bestandteil der Hauptkette des Polymers, der bei der Polymerisation
von Formaldehyd entsteht.
1.2 Die Arten von Polyoxymethylen-Kunststoffen werden mit Hilfe eines Einteilungssystems voneinander
unterschieden, das auf geeigneten Wertebereichen der folgenden kennzeichnenden Eigenschaften
a) Schmelze-Massefließrate oder Schmelze-Volumenfließrate;
b) Zug-Modul
und Informationen über grundlegende Polymerparameter, vorgesehene Anwendung, Verarbeitungsverfahren,
wichtige Eigenschaften, Additive, Farbstoffe, Füll- und Verstärkungsstoffe beruht.
1.3 Dieser Teil von ISO 9988 gilt für alle Polyoxymethylen-Homopolymere und -Copolymere und für
Polymermischungen, die Polyoxymethylen enthalten.
Er gilt für gebrauchsfertige Formmassen in Form von Pulver, Granulat oder Pellets und für mit Farbstoffen,
Additiven, Füllstoffen usw. modifizierte sowie für nicht modifizierte Materialien.
1.4 Es darf nicht unterstellt werden, dass Formmassen mit der gleichen Bezeichnung notwendigerweise ein
gleiches Leistungsverhalten zeigen. Dieser Teil von ISO 9988 enthält keine technischen Daten, Leistungs-angaben
oder Verarbeitungsbedingungen, die möglicherweise erforderlich sind, um Formmassen für
bestimmte Endanwendungen festzulegen.
Falls derartige zusätzliche Eigenschaften verlangt sind, müssen sie nach den in Teil 2 dieser Internationalen
Norm festgelegten Prüfverfahren bestimmt werden.
Plastiques - Matériaux a base de polyoxyméthylene (POM) pour moulage et extrusion - Partie 1: Systeme de désignation et base de spécification (ISO 9988-1:2004)
L'ISO 9988-1:2004 établit un système de désignation des matériaux thermoplastiques à base de polyoxyméthylène (POM) qui peut être utilisé comme base de spécification.
Les types de plastiques à base de polyoxyméthylène (POM) sont différenciés les uns des autres par un système de classification basé sur les niveaux appropriés des propriétés de désignation suivantes:
indice de fluidité à chaud en masse ou indice de fluidité à chaud en volume;
module en traction;
et sur des informations concernant les paramètres relatifs au polymère de base, l'application prévue, la méthode de mise en oeuvre, les propriétés importantes, les additifs, les colorants, les charges et les matériaux de renfort.
L'ISO 9988-1:2004 est applicable à tous les homopolymères du polyoxyméthylène ainsi qu'aux copolymères du polyoxyméthylène et aux mélanges de polymères contenant du polyoxyméthylène.
Elle s'applique aux matériaux prêts à l'emploi dans le cadre d'une utilisation normale sous la forme de poudre, granulés ou grains et aux matériaux non modifiés ou modifiés par des colorants, additifs, charges, etc.

ISO 9988-1:2004(E)
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 9988-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic
materials.
This third edition cancels and replaces the second edition (ISO 9988-1:1998), of which it constitutes a minor
revision in which the main changes are the deletion of the years of publication of the normative references in
Clause 2 and the updating of the number of the ASTM standard used in the second example in Clause 4.
ISO 9988 consists of the following parts, under the general title Plastics — Polyoxymethylene (POM) moulding
and extrusion materials:
— Part 1: Designation system and basis for specifications
— Part 2: Preparation of test specimens and determination of properties
