Full title and description

Thermoplastics pipes and fittings — Water absorption — Part 3: Test conditions for acrylonitrile/butadiene/styrene (ABS) pipes and fittings. Specifies the particular test conditions and preferred maximum value for water absorption of ABS pipes and fittings, and describes the test principle, procedure and reporting (including an informative Annex A).

Abstract

Defines the test conditions for determining water absorption of ABS thermoplastic pipes and fittings, gives a preferred maximum absorption value, and describes specimen preparation, immersion conditions and the measurement procedure. Annex A is informational.

Scope

Specifies the particular test conditions to be used when measuring water absorption of acrylonitrile/butadiene/styrene (ABS) pipes and fittings. The standard sets out required specimen types and preparation, immersion medium and temperature, test durations, measurement and calculation of absorption, and gives a preferred maximum value; the absorption values appropriate to specific applications are given in the relevant product standards. Annex A supplies additional information.

Key topics and requirements

• Definition of specimen types and conditioning before test (cutting, cleaning, dimensions).
• Specified immersion medium(s) and immersion temperature(s) for ABS test conditions.
• Test duration(s) and sampling intervals for water absorption measurement.
• Procedure for weighing and calculating percentage water absorption.
• Preferred maximum water absorption values for ABS (to be applied by product standards).
• Reporting requirements and inclusion of informative Annex A details.

Typical use and users

Used by manufacturers of ABS pipes and fittings, quality and materials testing laboratories, product development teams, conformity assessment and certification bodies, standards writers and specifiers who need standardized water absorption test conditions for ABS thermoplastic piping components.

FAQ

Q: What is this standard?

A: ISO 8361-3:1991 is an international standard that specifies test conditions for measuring water absorption of ABS (acrylonitrile/butadiene/styrene) pipes and fittings.

Q: What does it cover?

A: It covers specimen preparation, immersion media and temperature, test durations, measurement and calculation of water uptake, reporting and a preferred maximum absorption value (with informative annex material).

Q: Who typically uses it?

A: Manufacturers, testing laboratories, materials engineers, product standards committees, certification and conformity-assessment bodies, and specifiers for piping systems that use ABS components.

Q: Is it current or superseded?

A: The published 1991 edition has been periodically reviewed and was confirmed as the current edition in ISO's review process (confirmed as current following review). Users should check the ISO catalogue or national standards body for the latest status before purchase or citation.

Q: Is it part of a series?

A: Yes — ISO 8361 is a multipart series on water absorption of thermoplastic pipes and fittings; Part 1 covers the general test method and Part 2 covers PVC-U specific conditions. ISO 8361-3 is the ABS-specific part.
