Plastics - Thermoplastic polyester (TP) moulding and extrusion materials - Part 1: Designation system and basis for specification (ISO 20028-1:2017)
ISO 20028-1:2017 establishes a system of designation for thermoplastic polyester (TP) material, which can 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), poly(butylene naphthalates) (PBN) and other TP-types and copolyesters of various compositions for moulding and extrusion.
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.
This designation system 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, fillers and other additives. This document does not apply to the saturated polyester/ester and polyether/ester thermoplastic elastomers covered by ISO 20029.
It is not intended to imply that materials having the same designation give necessarily the same performance. This document 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 are intended to be determined in accordance with the test methods specified in ISO 20028‑2, if suitable.
In order to designate a thermoplastic polyester material to meet particular specifications, the requirements are to be given in data block 5 (see 4.1).
Kunststoffe - Thermoplastische Polyester (TP)-Formmassen - Teil 1: Bezeichnungssystem und Basis für Spezifikationen (ISO 20028-1:2017)
Dieses Dokument legt ein Bezeichnungssystem für thermoplastische Polyester (TP) Werkstoffe fest, das als Grundlage für Spezifikationen angewendet werden kann. Es umfasst Polyester Homopolymere (Reinpoly-merisate) für Werkstoffe auf Basis von Poly(ethylenterephthalat) (PET), Poly(butylenterephthalat) (PBT), Poly(cyclohexylendimethylenterephthalat) (PCT), Poly(ethylennaphthalat) (PEN), Poly(butylennaphthalat) (PBN) und andere TP Arten sowie Copolyester verschiedener Zusammensetzungen zum Formen und Extrudieren.
Die Arten thermoplastischer Polyester werden mithilfe eines Einteilungssystems voneinander unter-schieden, das auf geeigneten Wertebereichen der kennzeichnenden Eigenschaften
a) Viskositätszahl;
b) Zugelastizitätsmodul;
und auf Angaben über die vorgesehene Anwendung und/oder das vorgesehene Verarbeitungsverfahren, wichtige Eigenschaften, Additive, Farbstoffe, Füll und Verstärkungsstoffe beruht.
Dieses Bezeichnungssystem gilt für thermoplastische Polyester-Homopolymere und -Copolymere. Es gilt für gebrauchsfertige Werkstoffe in Form von Pulver, Granulat oder Pellets, nicht modifiziert oder modifiziert mit Farbstoffen, Füllstoffen und anderen Additiven. Dieses Dokument gilt nicht für gesättigte Polyester/Ester und Polyether/Ester Thermoplastelastomere, die in ISO 20029 behandelt werden.
Es sollte nicht unterstellt werden, dass Werkstoffe mit gleicher Bezeichnung das gleiche Leistungsverhalten aufweisen. Dieses Dokument enthält keine technischen Daten, Leistungsangaben oder Daten zu Verarbeitungsbedingungen, die erforderlich sein können, um einen Werkstoff zu spezifizieren. Wenn derartige zusätzliche Eigenschaften erforderlich sind, werden diese, soweit möglich, nach denen in ISO 20028 2 festgelegten Prüfverfahren bestimmt.
Um einen thermoplastischen Polyester-Werkstoff so zu bezeichnen, dass er besonderen Spezifikationen entspricht, sind zusätzliche Anforderungen im Daten Block 5 anzuführen (siehe 3.1).
Plastiques - Polyesters thermoplastiques (TP) pour moulage et extrusion — Partie 1 : Système de désignation et base de spécification (ISO 20028-1:2017)
ISO 20028-1:2017 établit un système de désignation des matériaux polyesters thermoplastiques (TP) qui peut être utilisé comme base pour les spécifications. Elle s'applique aux homopolymères des polyesters pour moulage et extrusion à base de poly(téréphtalate d'éthylène) (PET), de poly(téréphtalate de butylène) (PBT), de poly(téréphtalate de cyclohexylène diméthylène) (PCT), de poly(naphtalate d'éthylène) (PEN), de poly(naphtalate de butylène) (PBN) et autres types de TP, ainsi qu'aux copolyesters de compositions variables pour moulage et extrusion.
Les types de polyesters thermoplastiques sont différenciés les uns des autres par un système de classification fondé sur des niveaux appropriés des propriétés de désignation:
a) indice de viscosité;
b) module d'élasticité en traction;
et des informations sur l'application prévue et/ou la méthode de mise en ?uvre, les propriétés importantes, les additifs, les colorants, les charges et les matériaux de renfort.
Ce système de désignation s'applique aux homopolymères et copolymères de polyesters thermoplastiques. Il s'applique aux matériaux prêts à l'emploi sous forme de poudres, grains ou granulés, non modifiés ou modifiés par des colorants, charges et autres additifs. Le présent document ne s'applique pas aux élastomères thermoplastiques à base de copolymères saturés polyester/ester et polyéther/ester couverts par l'ISO 20029.
Le fait que des matériaux aient la même désignation n'implique pas qu'ils présentent nécessairement les mêmes performances. Le présent document ne comporte pas de données sur la conception, les performances ou les conditions de mise en ?uvre qui peuvent être exigées pour spécifier un matériau. Si de telles caractéristiques supplémentaires sont nécessaires, elles doivent être déterminées conformément aux méthodes d'essai spécifiées dans l'ISO 20028‑2, s'il y a lieu.
Afin de spécifier un matériau polyester thermoplastique répondant à des spécifications particulières, les exigences doivent être codées dans le bloc de données 5 (voir 4.1).
Polimerni materiali - Materiali za oblikovanje in ekstrudiranje iz plastomernih poliestrov - 1. del: Sistem označevanja in podlage za specifikacije (ISO 20028-1:2017)
Ta dokument določa sistem označevanja materialov iz plastomernih poliestrov (TP), ki jih je mogoče uporabiti kot podlago za specifikacije. Zajema poliestrske homopolimere za oblikovanje in ekstrudiranje na osnovi poli(etilen tereftalata) (PET), poli(butilen tereftalata) (PBT), poli(cikloheksilendimetilen tereftalata) (PCT), poli(etilen naftalata) (PEN), poli(butilen naftalata) (PBN) in druge vrste plastomernih poliestrov in kopoliestrov različnih kompozitov za oblikovanje in ekstrudiranje.
Vrste plastomernih poliestrov se med seboj ločujejo glede na sistem razvrščanja, ki temelji na ustreznih ravneh označevalnih lastnosti:
a) viskoznostnem številu;
b) nateznih modulih elastičnosti;
ter informacijah o predvideni uporabi in/ali metodi obdelave, pomembnih lastnostih, aditivih, barvilih, polnilih in materialih za ojačanje.
Ta sistem označevanja se uporablja za plastomerne poliestrske homopolimere in kopolimere. Uporablja se za materiale v obliki praška, granul ali peletov, pripravljenih za običajno uporabo, nespremenjenih ali spremenjenih z barvili, polnili in drugimi aditivi. Ta dokument se ne uporablja za nasičene plastomerne elastomere poliester/ester in polieter/ester iz standarda ISO 20029.
Materiali z enako oznako nimajo nujno tudi enakih lastnosti. Ta dokument ne zagotavlja inženirskih podatkov, podatkov o delovanju ali podatkov o pogojih obdelave, ki so mogoče potrebni za določitev materiala. Če so take dodatne lastnosti zahtevane, se določijo v skladu s preskusnimi metodami iz standarda ISO 20028-2, če je to primerno.
Da bi se določil material iz plastomernih poliestrov, ki ustreza določenim specifikacijam, se v podatkovnem bloku 5 navedejo dodatne zahteve (glej točko 3.1).

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9,
Thermoplastic materials.
This first edition of ISO 20028-1 cancels and replaces ISO 7792-1:2012, which has been technically
revised to introduce a new designation system.
The revised designation system is published under a new ISO number, as many existing documents
refer to ISO 7792-1. If the existing ISO 7792-1 would be replaced by the new designation system, these
documents would refer to the incorrect designation system.
In order to give users time to switch from ISO 7792-1 to ISO 20028-1, any designation system according
to ISO 7792-1 is to be phased out in 5 to 10 years.
A list of all parts in the ISO 20028 series can be found on the ISO website.

Introduction
ISO 7792-1 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, for example, marking. The
aim of this revision 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.
