Kunststoffe - Thermoplastische Polyester (TP)-Formmassen - Teil 1: Bezeichnungssystem und Basis für Spezifikationen (ISO 7792-1:1997)

1.1   Dieser Teil von ISO 7792 legt ein Bezeichnungssystem für Formmassen thermoplastischer Polyester (TP) fest, das als Grundlage für Spezifikationen verwendet kann.
Berücksichtigt werden Polyester-Homopolymere (Reinpolymerisate) für Formmassen auf Basis von Polyethylenterephthalat (PET), Polybutylenterephthalat (PBT), Polycyclohexylendimethylenterephthalat (PCT), Polyethylennaphthalat (PEN) und andere TP-Arten sowie Polyester-Copolymere verschiedener Zusammensetzung für Formmassen.
1.2   Die Arten thermoplastischer Polyester werden mit Hilfe eines Einteilungssystems voneinander unterschieden, das auf geeigneten Wertebereichen der folgenden kennzeichnenden Eigenschaften:
a)   Viskositätszahl;
b)   Zugelastizitätsmodul;
und auf Angaben über Zusammensetzung, vorgesehene Verwendung und/oder Verarbeitungsverfahren, wichtige Eigenschaften, Additive, Farbstoffe, Füll- und Verstärkungsstoffe beruht.
1.3   Dieser Teil von ISO 7792 gilt für Rein- und Copolymerisate thermoplastischer Polyester.
Die Norm gilt für gebrauchsfertige Werkstoffe in Form von Pulver, Granulat oder Pellets, die mit Farbstoffen, Additiven, Füllstoffen usw. modifiziert sein können.
Dieser Teil von ISO 7792 gilt nicht für Formmassen gesättigter Polyester/Ester- und Polyether/Ester-Thermoplastelastomere, die in ISO 16910 behandelt werden.
1.4   Es soll nicht behauptet werden, dass Formmassen mit gleicher Bezeichnung zwangsläufig Gleiches leisten. Dieser Teil von ISO 7792 enthält keine technischen Daten, Leistungsangaben oder Verarbeitungsbedingungen, die erforderlich sein können, um eine Formmasse für eine spezielle Anwendung und/oder ein bestimmtes Verarbeitungsverfahren zu spezifizieren.
Wenn derartige zusätzliche Eigenschaften gefragt sind, müssen sie, so weit möglich, nach den in Teil 2 dieser Internationalen Norm festgelegten Prüfverfahren bestimmt werden.

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.
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.
International Standard ISO 7792-1 was prepared by Technical Committee
ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials.
This third edition cancels and replaces the second edition
(ISO 7792-1:1995) and includes the following changes:
— The scope has been expanded to include all polyester homopolymers
and copolymers.
— The title has been changed from
Plastics — Poly(alkylene
terephthalate) moulding and extrusion materials to Plastics —
Thermoplastic polyester (TP) moulding and extrusion materials to
reflect the change in scope.
ISO 7792 consists of the following parts, under the general title Plastics —
Thermoplastic polyester (TP) moulding and extrusion materials:
— Part 1: Designation system and basis for specifications
— Part 2: Preparation of test specimens and determination of properties

INTERNATIONAL STANDARD  ISO ISO 7792-1:1997(E)
Plastics — Thermoplastic polyester (TP) moulding and extrusion
materials —
Part 1:
Designation system and basis for specifications
1  Scope
1.1  This part of ISO 7792 establishes a system of designation for thermoplastic polyester (TP) material, which may
be used as the basis for specifications.
It covers polyester homopolymers for moulding and extrusion based on poly(ethylene terephthalate) (PET),
poly(butylene terephthalate) (PBT), poly(cyclohexylenedimethylene terephthalate) (PCT), poly(ethylene
naphthalate) (PEN) and other TP-types and copolyesters of various compositions for moulding and extrusion.
1.2  The types of thermoplastic polyester 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 on information about the intended application and/or method of processing, important properties, additives,
colorants, fillers and reinforcing materials.
1.3  This part of ISO 7792 is applicable to thermoplastic polyester homopolymers and copolymers.
It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by
colorants, additives, fillers, etc.
This part of ISO 7792 does not apply to the saturated polyester/ester and polyether/ester thermoplastic elastomers
covered by ISO 14910.
1.4  It is not intended to imply that materials having the same designation give necessarily the same performance.
This part of ISO 7792 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
part 2 of this International Standard, if suitable.
1.5  In order to specify a thermoplastic polyester material for a particular application or to ensure reproducible
processing, additional requirements may be given in data block 5.

3  Designation system
The designation system for thermoplastics is based on the following standardized pattern:
Designation
Identity block
Individual-item block
Description block
(optional)
International
Data Data Data Data Data
Standard number
block block block block block
block
1 2 3 4 5
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 5 data blocks comprising the following information:
— Data block 1: Identification of the plastic by its symbol PET, PBT, PCT or PEN, or TP for all such
polyesters and copolyesters in general, in accordance with ISO 1043-1 (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).
— Data block 3: Designatory properties (see 3.3).
— Data block 4: Fillers or reinforcing materials and their nominal content (see 3.4).
— Data block 5: Information required for specification purposes. The use of data block 5 converts the
designation to a specification. Only information listed in data block 5 becomes part of the
specification requirements.
