Full title and description

Plastics — Polyetheretherketone (PEEK) moulding and extrusion materials — Part 1: Designation system and basis for specifications. This document establishes a structured designation system for PEEK moulding and extrusion materials that can be used as the basis for material specifications and product labelling.

Abstract

Defines a designation format and classification system for PEEK grades based on key designatory properties (melt viscosity or melt volume‑flow rate, tensile modulus and tensile strength) and on information about intended application, processing method, additives, colourants, fillers and reinforcements. The standard applies to PEEK supplied as powder, granules or pellets, unmodified or modified, and notes that designation does not guarantee identical performance — additional test requirements are to be specified where needed (see ISO 23153‑2).

Scope

Specifies a designation system for all polyetheretherketone (PEEK) moulding and extrusion materials that can be used as the basis for commercial and technical specifications. It covers designation blocks for identity, fillers/reinforcements, intended application/processing and important properties, the coding of designatory properties (MV/MVR, tensile modulus and tensile strength), and an optional data block for additional requirements to make a designation a full specification. It does not itself provide engineering or processing data — where such properties are required they are to be determined by referenced test methods (see ISO 23153‑2).

Key topics and requirements

• Designation format: structured individual-item block divided into five data blocks (identity, fillers/reinforcements, application/processing/additives, designatory properties, optional additional requirements).
• Melt property coding: melt viscosity (MV) and melt volume‑flow rate (MVR) are captured as coded test‑condition + range values to allow concise material grading.
• Mechanical property coding: tensile modulus and tensile strength are encoded into range codes so grades can be compared by mechanical class.
• Applicability: intended for PEEK in forms ready for normal use (powder, granules, pellets), unmodified or modified with colourants, fillers, reinforcements or other additives.
• Complementary test methods: where additional properties or reproducible test data are required, ISO 23153‑2 and referenced ISO test standards (e.g., for MVR, melt viscosity, tensile and thermal tests) are used.

Typical use and users

Used by polymer material manufacturers and compounders to label and publish grade designations; by OEMs and design engineers to specify PEEK grades for components; by procurement and quality teams to create purchase specifications; and by testing laboratories and standards committees that verify or reference material classes and test methods.

Related standards

ISO 23153‑2 (Preparation of test specimens and determination of properties) is the natural companion standard for test methods and specimen preparation. Other related standards referenced or commonly used with ISO 23153‑1 include ISO 1133 (MVR/MFR), ISO 11443 (melt viscosity), ISO 1043 (plastic material designation codes), ISO 527 (tensile testing), ISO 178 (flexural testing) and general material‑data standards such as ISO 10350.

FAQ

Q: What is this standard?

A: ISO 23153‑1:2020 is an ISO standard that defines a designation system and the basis for specifications for PEEK moulding and extrusion materials.

Q: What does it cover?

A: It covers the structure and codes used to describe PEEK grades (identity, fillers/reinforcements, intended use/processing, designatory properties and optional additional requirements) but does not itself give detailed engineering or processing data. For test methods and specimen preparation, see ISO 23153‑2.

Q: Who typically uses it?

A: Material producers, compounders, OEM design and materials engineers, procurement/specification writers, testing laboratories and standards committees use it to classify, specify and communicate PEEK grades.

Q: Is it current or superseded?

A: ISO 23153‑1:2020 was published in March 2020 and is the current edition; there is no published superseding edition as of 28 February 2026. The standard and its companion part (ISO 23153‑2) remain published and are subject to ISO's regular 5‑year review cycle.

Q: Is it part of a series?

A: Yes — it is Part 1 of the ISO 23153 series. Part 2 (ISO 23153‑2:2020) specifies specimen preparation and test methods; additional parts would cover further related subjects if developed.

Q: What are the key keywords?

A: PEEK; polyetheretherketone; designation; melt viscosity; MVR; tensile modulus; tensile strength; fillers; reinforcement; moulding; extrusion; material specification.
