ISO 23153-2:2020

Overview

ISO 23153-2:2020 - Plastics - Polyetheretherketone (PEEK) moulding and extrusion materials - Part 2 defines standardized procedures for the preparation of test specimens and the determination of properties of PEEK moulding and extrusion materials. The standard prescribes handling, pre‑treatment (drying), injection‑moulding conditions, specimen conditioning and the test methods to obtain reproducible, comparable data for rheological, mechanical, thermal, electrical and other material properties.

Key topics and requirements

• Specimen preparation: Injection moulding is the required specimen production method; specimens shall be produced using consistent processing conditions to ensure comparability.
• Material treatment before moulding: PEEK product shall be pre‑dried to a moisture level not greater than 0.05 % (ISO 15512 referenced).
• Injection‑moulding conditions (typical): melt temperature 360–400 °C (higher for filled grades), mould temperature 175–210 °C, injection velocity 100 ± 20 mm/s, cooling time 25 ± 10 s, total cycle time 60 ± 10 s (conditions based on ISO 20753 specimen A1).
• Specimen conditioning: Unfilled PEEK specimens - at least 16 h at 23 ± 2 °C (no RH requirement). Filled/additive‑sensitive specimens - 16 h at 23 ± 2 °C and 50 ± 10 % RH.
• Properties and test methods: The standard lists designated tests (selected from ISO 10350‑1 and other norms), including:
  • Rheological: MVR / MFR (ISO 1133‑1), melt viscosity (ISO 11443)
  • Dimensional: moulding shrinkage (ISO 294‑4)
  • Mechanical: tensile (ISO 527‑1/2), flexural (ISO 178), Charpy impact (ISO 179‑1)
  • Thermal: melting point and crystallization (DSC ISO 11357‑3), glass transition (ISO 11357‑2), HDT (ISO 75‑1/2), coefficient of linear thermal expansion (ISO 11359‑2)
  • Electrical: permittivity, dissipation factor, volume resistivity, dielectric strength, CTI (relevant IEC/ISO methods)
  • Other: water absorption (ISO 62), density (ISO 1183), burning behaviour (IEC 60695‑11‑10)

Applications and who uses it

• PEEK resin manufacturers for material specification, quality control and supplier declaration.
• Independent test laboratories to produce reproducible, comparable test data for reports and certification.
• OEMs and designers who require validated material properties for engineering design, component qualification and failure analysis.
• Procurement and regulatory teams for supplier qualification, material comparison and standards compliance in high‑performance applications (aerospace, medical, oil & gas, electrical insulation).

Related standards

• ISO 23153‑1 (designation system and basis for specifications)
• ISO 1133, ISO 527, ISO 178, ISO 294 series, ISO 15512, ISO 10350‑1 and relevant IEC electrical and fire‑test standards (all referenced within ISO 23153‑2).

Using ISO 23153‑2:2020 helps ensure consistent, comparable PEEK material data - critical for reliable component design, material selection and regulatory compliance.
