Plastics - Poly(phenylene sulfide) (PPS) moulding and extrusion materials - Part 1: Designation system and basis for specifications (ISO 20558-1:2018)
This document establishes a system of designation for poly(phenylene sulfide) (PPS) thermoplastic materials, which can be used as the basis for specifications.
The types of poly(phenylene sulfide) (PPS) materials are differentiated from each other by a classification system based on appropriate levels of the designatory properties
a) melt mass-flow rate or melt viscosity;
b) density;
c) tensile modulus;
and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.
This document is applicable to all PPS materials. It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc.
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 for a particular application and/or method of processing. If such additional properties are required, they are intended to be determined in accordance with the test methods specified in ISO 20558‑2, 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).

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 doivent être déterminées conformément aux méthodes d'essai spécifiées dans l'ISO 20558‑2, 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, des exigences sont codées dans le bloc de données 5 (voir 4.1).
Polimerni materiali - Materiali na osnovi polifenilensulfida (PPS) za oblikovanje in ekstrudiranje - 1. del: Sistem označevanja in podlage za specifikacije (ISO 20558-1:2018)
Ta dokument določa sistem označevanja plastomernih materialov na osnovi polifenilensulfida (PPS), ki jih je mogoče uporabiti kot podlago za specifikacije.
Vrste materialov na osnovi polifenilensulfida se med seboj ločujejo glede na sistem razvrščanja, ki temelji na ustreznih ravneh naslednjih označevalnih lastnosti:
a) masni pretok taline ali viskoznost taline;
b) gostota;
c) natezni modul;
ter informacijah o predvideni uporabi in/ali metodi obdelave, pomembnih lastnostih, aditivih, barvilih, polnilih in materialih za ojačanje.
Ta dokument se uporablja za vse vrste materialov PPS. Uporablja se za materiale v obliki praška, granul ali peletov, pripravljene za običajno uporabo, in materiale, nespremenjene ali spremenjene z barvili, aditivi, polnili itd.
Materiali z enako oznako nimajo nujno tudi enakih lastnosti. Ta dokument ne podaja tehničnih podatkov, podatkov o delovanju ali podatkov o pogojih obdelave, ki so morda potrebni za določitev materiala za določeno uporabo in/ali metodo obdelave. Če so take dodatne lastnosti zahtevane, se določijo v skladu s preskusnimi metodami, določenimi v standardu ISO 20558‑2, če je to primerno.
Zahteve za določanje plastomernega materiala za določeno uporabo ali zagotavljanje ponovljive obdelave so podane v podatkovnem bloku 5 (glej točko 4.1).

Overview
EN ISO 20558-1:2019 - Plastics: Poly(phenylene sulfide) (PPS) moulding and extrusion materials - Part 1: Designation system and basis for specifications defines a standardized designation system for PPS thermoplastic materials. It establishes how PPS grades are identified and described so they can form the basis of supplier and purchaser specifications. The standard applies to PPS in powder, granule or pellet form, unmodified or modified (colorants, additives, fillers, reinforcements).
Key topics and requirements
- Designation structure: A standardized pattern comprising an identity block (standard number + individual-item block) and up to five data blocks separated by commas. The individual-item block begins with a hyphen.
- Data block 1: Material identification - PPS symbol per ISO 1043‑1 and polymer composition.
- Data block 2: Fillers/reinforcements and nominal content (coded letters and numeric content). Mixtures can be combined, e.g. (GF25 + MD10).
- Data block 3: Intended application or processing method in position 1 (injection moulding, extrusion, etc.) and in positions 2–8 other properties, additives or colour information.
- Data block 4: Designatory properties used to differentiate grades - melt mass‑flow rate (MFR) or melt viscosity (MV), density, and tensile modulus.
- Data block 5: Optional specification block for additional requirements to ensure reproducible processing or application suitability.
- Scope limits: The standard provides a classification and designation basis but does not supply engineering performance data, processing conditions or detailed test methods. Where additional properties are required, ISO 20558‑2 is referenced for specimen preparation and property determination.
- Transition: ISO 20558‑1 replaces ISO 28078‑1:2009 and introduces a revised designation system (phased transition over several years).
Applications and users
- Who uses it:
- Material suppliers and resin producers for consistent grade identification and labelling
- OEMs and specifiers who create procurement specifications for PPS components
- Compounders and processors (injection moulding, extrusion) to communicate intended processing categories and additive/filler content
- Standards committees and test laboratories as a reference for grade coding
- Practical value:
- Enables clear, unambiguous communication of PPS grade characteristics (MFR/MV, density, modulus, fillers, processing class)
- Forms the baseline for material specifications and commercial datasheets
- Helps ensure consistency across supply chains when selecting PPS for electrical, automotive, industrial and high-temperature applications
Related standards
- ISO 20558-2 - Test methods and specimen preparation for PPS properties (referenced for additional property determination)
- ISO 1043-1 - Symbols and abbreviated terms for plastics (used for the PPS symbol)
- Note: EN ISO 20558‑1:2019 is the CEN-adopted version of ISO 20558‑1:2018.
Keywords: EN ISO 20558-1:2019, PPS designation system, poly(phenylene sulfide), thermoplastic materials, melt mass-flow rate, melt viscosity, density, tensile modulus, PPS specification.

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.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9,
Thermoplastic materials.
This first edition of ISO 20558-1 cancels and replaces ISO 28078-1:2009, 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 28078-1. If the existing ISO 28078-1 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 28078-1 to ISO 20558-1 any designation system according
to ISO 28078-1 is to be phased out in 5 to 10 years.
A list of all parts in the ISO 20558 series can be found on the ISO website.
