Full title and description

Plastics piping systems for hot and cold water installations — Polyethylene of raised temperature resistance (PE‑RT) — Part 2: Pipes. Specifies requirements for pipes made of PE‑RT (Type I and Type II) intended for hot and cold water installations within buildings and for heating systems, including applicable classes of application, design pressures, dimension classes and test methods.

Abstract

ISO 22391-2:2009 defines the characteristics, dimensions, mechanical and physical requirements, marking and test methods for PE‑RT pipes used in domestic and heating water systems. It covers pipes with or without barrier layers and is intended to be used together with other parts of the ISO 22391 series (general requirements, fittings, joints, etc.).

Scope

Specifies requirements for PE‑RT pipes (Type I and Type II) for conveying water in hot and cold water installations inside buildings (domestic and heating systems). The standard covers applicable classes of application, permitted design temperatures and pressures per class, pipe dimension classes, material and mechanical properties, test parameters and methods, and applicability to pipes with or without barrier layer(s). It is intended to be used in conjunction with ISO 22391‑1 (general) and the other parts of the ISO 22391 series for complete system specification.

Key topics and requirements

• Definitions and classification of PE‑RT materials (Type I and Type II).
• Permitted classes of application (service conditions) with associated design temperatures and pressures.
• Pipe dimension classes and geometric tolerances.
• Mechanical properties and performance criteria (e.g., burst strength, long‑term hydrostatic performance tests).
• Physical and chemical requirements, including suitability for potable water where applicable.
• Test parameters and methods for verification (type and routine tests).
• Marking, identification and information to be supplied by the manufacturer.
• Applicability to pipes with or without barrier layers and to joints/assemblies when used with other ISO 22391 parts.

Typical use and users

Used by pipe manufacturers, product designers, plumbing and heating engineers, specifiers, testing laboratories, certification bodies and regulatory authorities to design, produce, test and certify PE‑RT piping systems for hot and cold water and heating installations in buildings. It is referenced in product specifications, approvals and conformity assessments.
