EN ISO 24023-2:2020 PDF

Overview

EN ISO 24023-2:2020 - Plastics - Plasticized poly(vinyl chloride) (PVC-P) moulding and extrusion materials - Part 2 - defines standard procedures for preparing test specimens and determining the material properties of PVC‑P used in moulding and extrusion. It specifies handling, conditioning and specimen preparation (compression moulding, milling and machining) and lists the suitable test methods required to characterise PVC‑P materials for quality control, specification and comparative data reporting.

Key topics and technical requirements

• Specimen preparation: Specimens shall be produced reproducibly by compression moulding after plasticizing on a two‑roll mill. Milling and moulding parameters are given (milling roll temperatures and speeds, and moulding temperature bands) to ensure consistent sheet production prior to machining or stamping of test specimens.
• Milling and moulding conditions: The standard provides practical milling parameters (roll temperatures, milling time, roll speeds and dimensions) and compression‑moulding guidance (moulding temperature ranges, full‑pressure levels and times, preheating pressure/time and demoulding temperature) tailored to material hardness.
• Machining and specimen types: Test pieces are to be machined or stamped from compression‑moulded sheets in accordance with ISO 2818 and ISO 20753 (specimen types).
• Conditioning: All specimens shall be conditioned per ISO 291 - typically at 23 °C ± 2 °C and 50 % ± 10 % relative humidity for at least 48 hours prior to testing.
• Property determination: The document lists mechanical, electrical and other properties appropriate for PVC‑P and cites the test standards to use (for example ISO 527‑1/2 for tensile, ISO 868 for Shore hardness, ISO 1183‑1 for density and IEC 62631‑3‑1 for volume resistivity). Property selection and data presentation follow ISO 10350‑1 guidance.

Applications and who uses it

• Quality control laboratories conducting routine acceptance testing of PVC‑P compound batches.
• Material suppliers and compounders establishing specifications and verifying processing consistency.
• Product manufacturers and OEMs requiring comparable property data for component design and supplier evaluation.
• R&D teams developing new PVC‑P formulations and needing standardized test methods for comparative analysis.
• Standards writers and procurement specialists who reference reproducible test procedures for contract specifications and compliance.
