Overview

EN ISO 24024-2:2021 – Plastics – Homopolymer and Copolymer Resins of Vinyl Chloride – Part 2: Preparation of Test Samples and Determination of Properties – defines standardized methods for the preparation, conditioning, and testing of polyvinyl chloride (PVC) resin samples. This standard, published by CEN and identical to ISO 24024-2:2021, ensures that test results for vinyl chloride homopolymer (PVC-U) and copolymer resins (PVC-C, PVC-A, etc.) can be accurately compared, reproduced, and reported across laboratories, manufacturers, and regions.

The document replaces the former EN ISO 1060-2:1999, introducing updated procedures and undated normative references for increased flexibility in application.

Key Topics

• Sampling and Preparation: The standard outlines how to obtain representative resin samples and prepare standard pastes for testing, employing specific formulations and conditioning requirements.
• Conditioning Methods: Proper procedures are given for conditioning the test samples before property measurement, critical for ensuring reproducibility.
• Test Methodologies: Describes both the preparation of test specimens and the selection of appropriate testing methods required for evaluating key physical and chemical properties of PVC resins.
• Property Determination: Lists which properties are to be measured and references the appropriate ISO testing procedures for assessments such as apparent density, viscosity, bulk density, impurities, sieve analysis, absorption characteristics, and chemical composition.

Relevant keywords: PVC resin testing, vinyl chloride copolymers, test sample preparation, ISO plastic standards, physical property determination, chemical analysis of PVC.

Applications

EN ISO 24024-2:2021 is essential for industries and laboratories engaged in:

• Quality Control: Manufacturers can ensure raw PVC materials meet established physical and chemical property benchmarks.
• Product Development: R&D labs use these methods during the development of new PVC-based materials to guarantee consistency and performance.
• Regulatory Compliance: Meets regulatory demands for standardization and safety, especially where accurate reporting and certification of material properties are required.
• Supply Chain Consistency: Facilitates mutual understanding and agreement on material quality between resin producers, compounders, and end users.
• Comparative Analysis: Enables the direct comparison of resins from different sources by using harmonized preparation and test procedures.
• Accredited Testing Services: Laboratories offering accredited testing services rely on these procedures for customer reporting and certifications.

Related Standards

EN ISO 24024-2:2021 references several related ISO standards, ensuring comprehensive and harmonized testing:

• ISO 60: Determination of apparent density of pourable plastics
• ISO 1068: Measurement of compacted apparent bulk density of PVC resins
• ISO 1158: Determination of chlorine content in vinyl chloride resins
• ISO 1264, ISO 1265, ISO 1269: Determination of pH, impurities, and volatile matter in PVC
• ISO 1624, ISO 4610: Sieve analysis for PVC resins in water or by air-jet
• ISO 1628-2, ISO 2555, ISO 3219, ISO 4575: Viscosity measurement methods for PVC pastes and resins
• ISO 3451-5: Ash determination in PVC materials
• ISO 6401: Gas-chromatographic determination of residual vinyl chloride monomer

Note: The standard should be used in conjunction with the referenced ISO specifications to ensure full compliance and best practices in PVC resin testing.

By adhering to EN ISO 24024-2:2021, laboratories and manufacturers ensure accurate, repeatable results in the testing and quality assessment of polyvinyl chloride resins, supporting material performance, safety, and compliance across applications.

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).
