Plastics - Sulfone polymer moulding and extrusion materials - Part 1: Designation system and basis for specifications (ISO 24025-1:2020)

This document establishes a system of designation for sulfone polymer moulding and extrusion
materials, including polysulfone (PSU), polyethersulfone (PESU) and polyphenylsulfone (PPSU), which
can be used as the basis for specifications.
The types of sulfone polymer materials are differentiated from each other by a classification system
based on appropriate levels of the designatory properties
a) temperature of deflection under load,
b) melt mass-flow rate,
c) Charpy notched impact strength,
d) tensile modulus, and
e) yield stress,
and on information about composition, intended application and/or method of processing, important
properties, additives, colorants, fillers and reinforcing materials.
This document is applicable to all sulfone polymers that contain ether oxygen, which is a necessary
component of the polymers as in the diphenyl sulfone moiety. It applies to sulfone polymer materials
ready for normal use in the form of powder, granules or pellets, unmodified or modified by colorants,
additives, fillers, etc.
This document not intended to imply that materials having the same designation necessarily give
the same performance. It does not provide engineering data, performance data or data on processing
conditions which can be required to specify a material for a particular application and/or method of
processing.
If such additional properties are required, they are determined in accordance with the test methods
specified in ISO 24025-1, if suitable.
In order to specify a thermoplastic material for a particular application or to ensure reproducible
processing, the requirements are given in data block 5 (see 4.1).

Kunststoffe - Sulfonpolymer-Werkstoffe für das Spritzgießen und die Extrusion - Teil 1: Bezeichnungssystem und Basis für Spezifikationen (ISO 24025-1:2020)

Dieses Dokument legt ein System für die Bezeichnung von Sulfonpolymer-Werkstoffen für das Spritzgießen und die Extrusion fest, einschließlich Polysulfon (PSU), Polyethersulfon (PESU) und Polyphenylsulfon (PPSU), das als Basis für Spezifikationen angewendet werden kann.
Die Typen der Sulfonpolymer-Werkstoffe werden mit Hilfe eines Einteilungssystems voneinander unter¬schieden, das auf geeigneten Wertebereichen der kennzeichnenden Eigenschaften
a) Wärmeformbeständigkeitstemperatur,
b) Schmelze-Massefließrate,
c) Charpy-Kerbschlagzähigkeit,
d) Zugmodul, und
e) Streckspannung
und auf Informationen über Zusammensetzung, vorgesehene Anwendung und/oder Verarbeitungs-verfahren, wichtige Eigenschaften, Additive (Zusatzstoffe), Farbstoffe, Füll  und Verstärkungsstoffe beruht.
Dieses Dokument gilt für alle Sulfonpolymere, die Ethersauerstoff enthalten, welcher ein wichtiger Bestandteil der Polymere ist, wie der Diphenylsulfon-Rest. Es gilt für gebrauchsfertige Sulfonpolymer-Werkstoffe in Form von Pulver, Granulaten oder Pellets, die unmodifiziert oder mit Farbstoffen, Zusatzstoffen, Füllstoffen usw. modifiziert sind.
Mit diesem Dokument soll nicht unterstellt werden, dass Werkstoffe mit gleicher Bezeichnung notwendiger¬weise das Gleiche leisten. Es enthält keine technischen Daten, Leistungsangaben oder Angaben zu Verarbeitungsbedingungen, die erforderlich sein können, um einen Werkstoff für eine bestimmte Anwendung und/oder Verarbeitungsart zu spezifizieren.
Für den Fall, dass derartige zusätzliche Eigenschaften gefordert sind, werden diese, sofern angemessen, nach den in ISO 24025 1 festgelegten Prüfverfahren bestimmt.
Um einen thermoplastischen Werkstoff für eine bestimmte Anwendung zu spezifizieren oder eine reprodu¬zierbare Verarbeitung sicherzustellen, sind die Anforderungen im Datenblock 5 (siehe 4.1) angegeben.

Plastiques - Matériaux pour moulage et extrusion à base de polymères sulfone - Partie 1: Système de désignation et base de spécifications (ISO 24025-1:2020)

Le présent document établit un système de désignation des matériaux pour moulage et extrusion à base de polymères sulfone, y compris le polysulfone (PSU), le polyéthersulfone (PESU) et le polyphénylsulfone (PPSU), qui peut être utilisé comme base pour les spécifications.
Les types de matériaux à base de polymères sulfone sont différenciés les uns des autres par un système de classification fondé sur des niveaux appropriés des propriétés de désignation:
a)    température de fléchissement sous charge;
b)    indice de fluidité à chaud en masse;
c)    résistance au choc Charpy avec entaille;
d)    module en traction; et
e)    contrainte au seuil d'écoulement;
et des informations concernant la composition, l'application prévue et/ou la méthode de mise en œuvre, les propriétés importantes, les additifs, les colorants, les charges et les matériaux de renfort.
Le présent document s'applique à tous les polymères sulfone qui contiennent de l'éther-oxyde, qui est un composant nécessaire des polymères comme dans le groupe fonctionnel diphénylsulfone. Il s'applique aux matériaux à base de polymères sulfone prêts à l'emploi normal sous forme de poudre, de grains ou de granulés, non modifiés ou modifiés par des colorants, des additifs, des charges, etc.
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, la performance ou les conditions de mise en œuvre qui peuvent être exigées pour spécifier un matériau pour une application et/ou une méthode de mise en œuvre particulière.
Si de telles caractéristiques supplémentaires sont nécessaires, elles sont déterminées conformément aux méthodes d'essai spécifiées dans l'ISO 24025‑1, s'il y a lieu.
Afin de spécifier un matériau thermoplastique pour une application particulière ou d'assurer une méthode de mise en œuvre reproductible, les exigences sont codées dans le bloc de données 5 (voir 4.1).

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 25137-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9,
Thermoplastic materials.
ISO 25137 consists of the following parts, under the general title Plastics — Sulfone polymer moulding

Part 1:
Designation system and basis for specifications
1 Scope
1.1 This part of ISO 25137 establishes a system of designation for sulfone polymer moulding and
extrusion materials, including polysulfone (PSU), polyethersulfone (PESU) and polyphenylsulfone
(PPSU), which may be used as the basis for specifications.
1.2 The types of sulfone polymer materials are differentiated from each other by a classification system
based on appropriate levels of the designatory properties
a) temperature of deflection under load,
b) melt mass-flow rate,
c) Charpy notched impact strength,
d) tensile modulus and
e) yield stress,
and on information about composition, intended application and/or method of processing, important
properties, additives, colorants, fillers and reinforcing materials.
1.3 This part of ISO 25137 is applicable to all sulfone polymers that contain ether oxygen, which is a
necessary component of the polymers as in the diphenyl sulfone moiety.
It applies to sulfone polymer materials ready for normal use in the form of powder, granules or pellets,
unmodified or modified by colorants, additives, fillers, etc.
1.4 It is not intended to imply that materials having the same designation necessarily give the same
performance. This part of ISO 25137 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 material for a particular application or to ensure reproducible
processing, additional requirements may be given in data block 5 (see 3.1).
