Ta dokument določa sistem označevanja plastomernih materialov na osnovi polifenilenetra (PPE), ki jih je mogoče uporabljati kot podlago za specifikacije.
Vrste materialov na osnovi polifenilenetra se med seboj ločujejo glede na sistem razvrščanja, ki temelji na ustreznih ravneh naslednjih označevalnih lastnosti:
a) temperatura upogiba pod obremenitvijo;
b) volumski pretok taline;
c) zarezna udarna žilavost po Charpyju;
d) vnetljivost;
ter informacijah o parametrih osnovnega polimera, nameravani uporabi in/ali metodi obdelave,
pomembnih lastnostih, aditivih, barvilih, polnilih ter materialih za ojačanje.
Ta dokument se uporablja za vse materiale na osnovi polifenilenetra, vključno s tistimi, ki so spremenjeni s polistirenom ali poliamidom oziroma drugimi materiali.
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 lahko potrebni za določitev materiala za določeno uporabo in/ali metodo obdelave. Če so take dodatne lastnosti zahtevane, se določijo v skladu s preskusnimi metodami iz standarda ISO 20557-2, 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 20557-1:2018 (CEN adoption of ISO 20557-1:2018) defines a standardized designation system for poly(phenylene ether) (PPE) thermoplastic materials used for moulding and extrusion. The standard provides a structured coding method that can serve as the basis for material specifications, allowing suppliers, specifiers and manufacturers to communicate composition, key properties and additives in a consistent way. It applies to PPE in powder, granules or pellet form, including blends (e.g., PPE+PS, PPE+PA) and materials modified with colorants, fillers or reinforcements.
Key Topics
- Designation structure: A standardized pattern with an International identity block and an individual-item block subdivided into five data blocks (Data blocks 1–5) for clear, unambiguous coding.
- Data block content:
- Data block 1: Identification of plastic by the symbol PPE and a code-number for composition (examples: 1 = PPE, 2 = PPE+PS, 3 = PPE+PA).
- Data block 2: Fillers/reinforcements and their form and nominal mass content (single-letter codes plus numeric content; mixtures can be shown as e.g. (GF25+MD10) for 25% glass fibre + 10% mineral powder).
- Data block 3: Intended application or processing method (position 1) and important additives/properties (positions 2–8).
- Data block 4: Designatory properties used to differentiate types of PPE: temperature of deflection under load, melt volume-flow rate, Charpy notched impact strength, and flammability.
- Data block 5: Optional block for specification requirements or additional properties needed to ensure reproducible processing or application suitability.
- Scope limits: The standard does not provide engineering performance data, processing conditions or guarantee identical performance for identically designated materials.
- Test methods: When additional properties are required, they are intended to be measured per ISO 20557-2 (preparation of test specimens and determination of properties).
Applications
Who uses EN ISO 20557-1:2018 and why:
- Material suppliers and compounders - to label and describe PPE grades consistently for catalogues and datasheets.
- Product designers and OEMs - to select materials by designation blocks that match intended application requirements.
- Procurement and quality engineers - to create specification templates and acceptance criteria using Data block 5.
- Test laboratories and standards committees - to interpret designation codes and reference test methods.
- Regulatory and compliance teams - to reference flammability and material composition categories in regulatory filings.
Related Standards
- ISO 20557-2 - test specimen preparation and property determination for PPE (referenced for measurement of additional properties).
- ISO 1043-1 - plastics symbols and abbreviated terms (used for the PPE symbol).
- EN ISO 28941-1:2008 - previous designation system superseded by EN ISO 20557-1:2018.
This designation system improves clarity in material specification for PPE moulding and extrusion materials, helping stakeholders reduce ambiguity when communicating composition, fillers, processing intent and key designatory properties.

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 20557-1 cancels and replaces ISO 28941-1:2008, 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 28941-1. If the existing ISO 28941-1 would be replaced by the new designation system, these
documents would refer to the incorrect designation system.
The new designation system according to ISO 20557-1 is intended to replace gradually any designation
system according to ISO 28941-1.
