Full title and description

Plastics piping systems for hot and cold water installations — Crosslinked polyethylene (PE‑X) — Part 3: Fittings — Amendment 1 (ISO 15875-3:2003/Amd 1:2020). This amendment updates and clarifies requirements that apply to ISO 15875-3:2003 for fittings used with PE‑X piping systems in building hot and cold water and heating installations.

Abstract

ISO 15875-3:2003/Amd 1:2020 is a short amendment to ISO 15875-3:2003 which concerns the characteristics and test parameters for fittings for crosslinked polyethylene (PE‑X) piping systems used for domestic hot and cold water and heating applications. The amendment was published in December 2020 and has subsequently been withdrawn when the part was updated by a new edition.

• Number of pages: 2 (amendment document).

Scope

The amendment applies to ISO 15875-3:2003 and covers requirements and test parameter clarifications for fittings intended to be used with crosslinked polyethylene (PE‑X) piping systems for the conveyance of water in buildings (domestic hot and cold water and heating systems). It is intended to be used together with the other parts of the ISO 15875 series (notably part 1 and part 2) which define application classes, design temperatures and pressures, and pipe requirements.

Key topics and requirements

• Characteristics and performance requirements for fittings used with PE‑X piping systems (materials, dimensions, markings and mechanical properties).
• Specified test parameters and methods for verifying fitting performance under the applicable design pressures and temperatures.
• Application-class and design-pressure alignment with ISO 15875-1 and compatibility with pipes conforming to ISO 15875-2; joint requirements referenced to ISO 15875-5.
• Editorial and technical clarifications introduced by Amendment 1 to address identified gaps or to align with later practice prior to full revision.

Typical use and users

Used by standards committees, manufacturers of PE‑X fittings, product testing laboratories, plumbing and HVAC specifiers, architects and consulting engineers, building authorities and procurement teams who need to reference or verify fitting requirements for hot and cold water and heating installations. The amendment itself is brief and primarily of interest to organizations maintaining normative references and product conformity records.

Related standards

ISO 15875 series (notably ISO 15875-1 — general/definitions and application classes; ISO 15875-2 — pipes; ISO 15875-5 — jointing), national and regional EN ISO versions where adopted, and subsequent amendments and newer editions that replace the 2003 base (the part was later revised and republished as ISO 15875-3:2025).

FAQ

Q: What is this standard?

A: It is Amendment 1 (2020) to ISO 15875-3:2003, which provides updates and clarifications to the requirements and test parameters for fittings used with crosslinked polyethylene (PE‑X) piping systems for hot and cold water and heating installations.

Q: What does it cover?

A: The amendment covers clarifications to characteristics, test parameters and related requirements for fittings within the scope of ISO 15875-3:2003 — essentially technical and editorial changes that affect how fittings are specified and tested for domestic water and heating applications.

Q: Who typically uses it?

A: Manufacturers, test laboratories, standards bodies, specifiers, engineers and authorities responsible for product conformity and installation requirements in building water and heating systems.

Q: Is it current or superseded?

A: ISO 15875-3:2003/Amd 1:2020 has been withdrawn and the part has been superseded by a newer edition, ISO 15875-3:2025 (the 2025 edition is the current published replacement).

Q: Is it part of a series?

A: Yes — it is part of the ISO 15875 series for plastics piping systems for hot and cold water installations (multiple parts covering general requirements, pipes, fittings, joints and related aspects).
