Overview
ISO 2507-3:1995 defines the specific test conditions for determining the Vicat softening temperature (VST) of thermoplastic pipes and fittings made from ABS (acrylonitrile/butadiene/styrene) and ASA (acrylonitrile/styrene/acrylic ester). It supplements the general Vicat test method given in ISO 2507-1 and includes informative basic specifications for both ABS and ASA materials.
Key topics and technical requirements
- Scope: Applies to ABS and ASA pipes and fittings for VST determination under the ISO 2507 series.
- Reference method: Uses the general Vicat softening temperature method from ISO 2507-1; Part 3 prescribes material- and product-specific adjustments.
- Apparatus: Specifies using a temperature-controlled oven (see clause referencing oven 4.7) in place of a heating bath for the conditioning step.
- Specimen pre-drying: Pre-dry test specimens immediately before conditioning by placing them in a thermostatted oven at 90 °C ± 2 °C for 2 hours, then cool in air at 23 °C ± 2 °C and (50 ± 5) % RH for 15 min ± 1 min.
- Conditioning: After pre-drying, condition specimens in accordance with the conditioning procedure of ISO 2507-1 (article 6).
- Reporting: Test report content follows ISO 2507-1 (article 8) requirements.
- Informative specifications: Annex A (ABS) and Annex B (ASA) give basic VST specification guidance - both indicate a minimum VST of 90 °C under the prescribed test conditions (product standards may set stricter values where required).
Applications and who uses this standard
- Manufacturers of ABS and ASA plastic pipes and fittings use ISO 2507-3 to verify thermal performance and to support product specifications.
- Quality control and testing laboratories apply the specified pre-drying, conditioning and test apparatus requirements to produce repeatable VST results.
- Product standards writers, procurement teams and regulatory bodies reference the standard when defining acceptance criteria or compliance for piping systems exposed to elevated temperatures.
- Useful for stakeholders assessing material selection, performance under heat, or comparing thermoplastic pipe materials (ABS/ASA) for building services, drainage, or industrial piping.

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. Esch 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.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 2507-3 was prepared by Technical Committee
lSO/TC 138, Plastics pipes, fittings and valves for the transport of fluids,
Subcommittee SC 5, General properties of pipes, fittings and valves of
plastic materials and their accessories - Test methods and basic specifi-
ca tions.

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.
