Full title and description

Plastics piping systems for hot and cold water installations — Polyethylene of raised temperature resistance (PE-RT) — Part 1: General. This part specifies general characteristics, terminology, classes of application, service conditions, design pressures and temperatures, and test parameters applicable to PE‑RT Type I and Type II piping systems, their fittings and joints for hot and cold water installations within buildings (including domestic and heating systems).

Abstract

ISO 22391-1:2009 provides the foundational requirements for PE‑RT piping systems used in building hot and cold water installations. It defines terms, application classes and required service conditions, and sets out the scope of application for pipes, fittings and joints including combinations with other materials; it is intended to be used together with the other parts of the ISO 22391 series that cover detailed requirements for pipes, fittings, marking and system fitness-for-purpose.

Scope

Specifies general requirements applicable to PE‑RT (Type I and Type II) piping systems for conveying hot and cold water in buildings, whether or not the water is for human consumption. The standard covers classes of application, appropriate service conditions, design pressures and temperatures, definitions of terms and the test parameters to be used when assessing pipes, fittings and joints. Specific geometric, mechanical and marking requirements are provided in other parts of the ISO 22391 series.

Key topics and requirements

• Definition and terminology for PE‑RT piping systems (Type I and Type II).
• Classes of application and corresponding design temperatures and pressures.
• General material and performance requirements for pipes, fittings and joints used in hot and cold water installations.
• Test parameters and methods to assess performance and long-term behaviour under specified service conditions.
• Guidance on system composition — pipes, fittings and joints including combinations with other materials; detailed specifications covered in subsequent parts of the series.

Typical use and users

Used by manufacturers of PE‑RT pipes and fittings, product designers and system engineers, plumbing and heating installers, test laboratories, conformity assessment bodies, and regulatory authorities responsible for building services and potable-water systems. It supports specification, testing and assessment of piping systems for domestic and heating water applications.

Related standards

Part of the ISO 22391 series; related parts include ISO 22391-2 (pipes — detailed properties), ISO 22391-3 (fittings), and ISO 22391-5 (fitness for purpose / system assessment). Many national bodies and CEN have adopted EN/ISO versions (for example DIN/EN ISO adoption) for use in regional markets and regulatory frameworks.

FAQ

Q: What is this standard?

A: ISO 22391-1:2009 is the international standard that establishes general requirements and terminology for polyethylene of raised temperature resistance (PE‑RT) piping systems used in hot and cold water building installations.

Q: What does it cover?

A: It covers general characteristics, classes of application, appropriate service conditions, design pressures and temperatures, and test parameters for PE‑RT Type I and Type II pipes, fittings and joints; detailed dimensional, mechanical and marking requirements are in other parts of the ISO 22391 series.

Q: Who typically uses it?

A: Manufacturers, designers, installers, test laboratories, conformity assessors and regulators involved in plumbing and heating systems for buildings.

Q: Is it current or superseded?

A: The 2009 (Edition 2) text is published and — according to ISO's review records — has been confirmed in periodic reviews; it remains the current edition unless a later revision has been published after the last review confirmation. Users should check the official national or ISO catalogue for the absolute latest status before regulatory or procurement decisions.

Q: Is it part of a series?

A: Yes — ISO 22391 is a multipart standard. Part 1 gives general requirements; other parts (for example Part 2, Part 3 and Part 5) address pipes, fittings, marking and fitness-for-purpose assessments.

Q: What are the key keywords?

A: PE‑RT, polyethylene, raised temperature resistance, piping systems, hot water, cold water, plumbing, heating, pipes, fittings, joints.
