Full title and description

Plastics piping systems — Thermoplastics pipes and fittings for hot and cold water — Test method for the resistance of mounted assemblies to temperature cycling. This International Standard specifies a laboratory test method to assess the ability of mounted pipe and fitting assemblies (joints) made from thermoplastics to withstand repeated changes in temperature representative of hot and cold water pressure applications.

Abstract

ISO 19893:2011 specifies a method for testing the resistance to temperature cycling of joints for piping systems with rigid or flexible thermoplastics pipes. It is applicable to thermoplastics piping systems intended to be used in hot and cold water pressure applications.

Scope

This standard defines a laboratory test method to determine the resistance of mounted assemblies (joints) of thermoplastic pipes and fittings to repeated temperature cycling. The procedure is intended for assemblies used in hot and cold water pressure applications and applies to both rigid and flexible thermoplastics piping systems. The test helps evaluate whether joints maintain integrity and performance when exposed to alternating hot and cold water conditions representative of service.

Key topics and requirements

• Definition and preparation of test specimens: representative mounted assemblies (pipe/fitting joints) for testing.
• Temperature-cycling procedure: alternating hot and cold water exposures to simulate service conditions.
• Applicability: test covers assemblies for pressure applications in hot and cold water systems, including rigid and flexible thermoplastics.
• Performance assessment: criteria for detecting leaks, deformation or loss of joint integrity after cycling.
• Use in type-testing, quality verification and R&D for piping systems and jointing methods.

Typical use and users

Manufacturers of thermoplastic pipes and fittings, independent testing laboratories, conformity assessment bodies, product certification schemes, plumbing and building services engineers, specification writers and regulators use this standard to verify joint durability under temperature variations representative of hot and cold water service.

Related standards

ISO 19893:2011 is part of a family of ISO test methods and specifications for thermoplastics piping systems and is linked to other ISO documents dealing with joint and assembly performance (for example ISO 19892 — resistance of joints to pressure cycling; ISO 19899 — AREL/end-load tests for polyolefin pipe assemblies) as well as related tests for temperature-cycling resistance in non-pressure applications (ISO 13260, ISO 13257 and others). These related documents are produced under ISO/TC 138 and its subcommittees.
