Overview
ISO 2507-2:1995 - Thermoplastics pipes and fittings - Vicat softening temperature - Part 2 specifies the particular test conditions for determining the Vicat softening temperature (VST) of PVC materials used in pipes and fittings. It applies to unplasticized poly(vinyl chloride) (PVC-U), chlorinated poly(vinyl chloride) (PVC-C) and high impact resistance poly(vinyl chloride) (PVC-HI) pipes and fittings. The general test method is given in ISO 2507-1:1995; this Part 2 adds material‑specific conditions and informative basic VST specifications.
Key Topics and Requirements
- Purpose: define test conditions to determine the Vicat softening temperature for PVC-U, PVC-C and PVC-HI pipework components.
- Normative reference: relies on the general procedure, apparatus, specimen preparation, conditioning, procedure and reporting defined in ISO 2507-1.
- Material scope:
- PVC-U (pipes and moulded fittings)
- PVC-C (pressure and non‑pressure pipes and fittings)
- PVC-HI (high impact resistance pipes)
- Informative basic VST specifications (given in annexes A–C):
- PVC-U pipes: not less than 79 °C
- PVC-U moulded fittings: not less than 77 °C
- PVC-C pressure pipes: not less than 110 °C
- PVC-C fittings: not less than 103 °C
- PVC-C non‑pressure pipes: not less than 90 °C
- PVC-HI pipes: not less than 76 °C
- Annexes A, B and C provide basic specification values for information; product standards may specify more stringent limits for particular applications.
Applications and Who Uses It
- Manufacturers of PVC-U, PVC-C and PVC-HI pipes and fittings use ISO 2507-2 for product testing and quality control to demonstrate temperature performance.
- Test laboratories and certification bodies apply the specified test conditions when reporting Vicat softening temperature for compliance and labeling.
- Engineers, specifiers and procurement professionals use VST data to select pipe materials for temperature-critical fluid transport systems (e.g., hot water, industrial services).
- Regulators and standards committees reference these test conditions when developing or harmonizing product standards and safety requirements.
Related Standards
- ISO 2507-1:1995 - Thermoplastics pipes and fittings - Vicat softening temperature - Part 1: General test method (primary reference for apparatus and procedure).

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération
mondiale d’organismes nationaux de normalisation (comités membres de
I’ISO). L’élaboration des Normes internationales est en général confiée aux
comités techniques de I’ISO. Chaque comité membre intéressé par une
étude a le droit de faire partie du comité technique créé à cet effet. Les
organisations internationales, gouvernementales et non gouvernemen-
tales, en liaison avec I’ISO participent également aux travaux. L’ISO colla-
bore étroitement avec la Commission électrotechnique internationale (CEI)
en ce qui concerne la normalisation électrotechnique.
Les projets de Normes internationales adoptés par les comités techniques
sont soumis aux comités membres pour vote. Leur publication comme
Normes internationales requiert l’approbation de 75 % au moins des co-
mités membres votants.
