Full title and description

Plastics piping systems for hot and cold water installations — Polyethylene of raised temperature resistance (PE-RT) — Part 5: Fitness for purpose of the system. This part of ISO 22391 specifies the fitness‑for‑purpose characteristics, applicable service classes, design pressures and temperatures, and required test parameters and methods for piping systems and their joints made from PE‑RT (Type I and Type II) used in building hot and cold water and heating installations.

Abstract

ISO 22391-5:2009 defines the characteristics that demonstrate the fitness for purpose of PE‑RT piping systems (pipes, fittings and their joints), covering a range of application classes, design pressures and pipe dimension classes. It specifies test parameters and test methods for verifying resistance to internal pressure, leak tightness, mechanical pull‑out, thermal cycling and other performance attributes required for domestic hot/cold water and heating systems, in conjunction with the other parts of ISO 22391.

Scope

Specifies the fitness‑for‑purpose characteristics of piping systems made from PE‑RT (Type I and Type II) intended for hot and cold water installations inside buildings (domestic water and heating systems). The standard applies to PE‑RT pipes, fittings and joints (including joints with components of other plastics or non‑plastic materials) for the range of service classes, design pressures and temperatures defined in ISO 22391‑1. It is to be used together with the other parts of the ISO 22391 system standard.

Key topics and requirements

• Definition of fitness‑for‑purpose characteristics for PE‑RT piping systems (material types: PE‑RT Type I and II).
• Classification of application/service classes with corresponding design pressures and temperatures.
• Specified test parameters and test methods for: resistance to internal pressure, leak tightness under pressure and bending, pull‑out resistance of joints, and thermal cycling performance.
• Requirements and evaluation rules for pipes, fittings and complete joints (including mixed‑material joints where applicable).
• Reference to the system‑level requirements given in ISO 22391‑1 (general) and to parts addressing pipes and fittings.

Typical use and users

Manufacturers of PE‑RT pipes and fittings; product design and R&D teams; conformity assessment and testing laboratories; plumbing and heating system designers and specifiers; national standards bodies and regulators; procurement teams and quality managers responsible for material and system selection for building water and heating installations.

FAQ

Q: What is this standard?

A: ISO 22391‑5:2009 is the Part 5 document of the ISO 22391 system standard that specifies fitness‑for‑purpose requirements and test parameters for PE‑RT piping systems used in building hot/cold water and heating installations.

Q: What does it cover?

A: It covers required characteristics, applicable service classes, design pressures/temperatures and the test methods/parameters used to assess pipes, fittings and joints made from PE‑RT (Type I and II), including mixed‑material joints used in domestic and heating systems.

Q: Who typically uses it?

A: Product manufacturers, testing laboratories, specifiers, installers, regulatory bodies and anyone responsible for specifying or demonstrating the fitness for purpose of PE‑RT piping systems in buildings.

Q: Is it current or superseded?

A: The 2009 second edition (ISO 22391‑5:2009, ed.2) is the published version and an amendment (ISO 22391‑5:2009/Amd 1:2020) has been issued; the original 2007 edition was withdrawn when the 2009 edition was published. Confirm current status and any later revisions from ISO before relying on the standard for procurement or compliance.

Q: Is it part of a series?

A: Yes — ISO 22391 is a multipart system standard for PE‑RT piping systems. Parts include at least Part 1 (General), Part 2 (Pipes), Part 3 (Fittings) and Part 5 (Fitness for purpose). National and regional adoptions (EN ISO versions) and amendments accompany the series.

Q: What are the key keywords?

A: PE‑RT; polyethylene; plastics piping systems; hot water; cold water; fitness for purpose; joints; service classes; design pressure; thermal cycling.
