Full title and description

STB DIN EN ISO 15875-3 2004-03 — Plastics piping systems for hot and cold water installations — Crosslinked polyethylene (PE‑X) — Part 3: Fittings. (Adoption of ISO 15875-3:2003 as a DIN/EN/ISO publication; German title: Kunststoff-Rohrleitungssysteme für die Warm- und Kaltwasserinstallation – Vernetztes Polyethylen (PE‑X) – Teil 3: Formstücke.)

Abstract

This document specifies requirements, test methods and marking for fittings made of crosslinked polyethylene (PE‑X) intended for use in hot and cold potable water piping systems. It covers material characteristics, mechanical and hydrostatic performance, dimensional and marking requirements and type/production testing needed to demonstrate fitness for purpose.

Scope

This part of ISO 15875 applies to fittings manufactured from crosslinked polyethylene (PE‑X) intended to join PE‑X pipes in potable hot and cold water distribution systems inside buildings. It defines required material properties, type and production tests (including hydrostatic/higher-temperature tests), dimensions, performance/pressure classes and marking necessary to ensure safe service life in plumbing applications. The standard is focused on fittings (bodies and stress-bearing components) and on tests that demonstrate resistance to internal pressure, thermal exposure and mechanical stresses.

Key topics and requirements

• Scope and definitions specific to PE‑X fittings (material layers, auxiliary plastic parts, single‑layer vs multi‑layer constructions).
• Material requirements including degree of crosslinking, thermal stability and suitability for potable water contact.
• Hydrostatic pressure and endurance tests (per ISO 1167 series) with specified test temperatures and durations to verify long‑term pressure performance.
• Mechanical requirements (burst/leakage, tensile and compression behavior where applicable) and sampling/testing regimes for type and production control.
• Dimensional tolerances, interface compatibility with PE‑X pipes and mating components, and marking/traceability requirements for fittings.
• Requirements for auxiliary plastic parts not in contact with water but subject to mechanical stress and temperature (thermal stability or applicable tests).

Typical use and users

Manufacturers of PE‑X fittings and pipe systems, plumbing and heating product specifiers, test laboratories performing type and production testing, installers and contractors specifying compliant fittings for potable hot and cold water systems, and national standards bodies or certification organizations referencing EN/ISO requirements for building plumbing.

FAQ

Q: What is this standard?

A: It is the national adoption (DIN EN ISO) of ISO 15875-3:2003, the part of the ISO 15875 series that specifies requirements and tests for fittings made from crosslinked polyethylene (PE‑X) used in hot and cold potable water installations.

Q: What does it cover?

A: The standard covers material properties (including crosslinking and thermal stability), mechanical and hydrostatic performance tests (including long‑term/temperature tests), dimensional and interface requirements, marking and traceability, and requirements for auxiliary plastic parts of fittings.

Q: Who typically uses it?

A: Manufacturers of PE‑X fittings, test laboratories, product certifiers, plumbing/heating specifiers and installers, and standards bodies reference this document when specifying, testing or certifying PE‑X fittings for building potable water systems.

Q: Is it current or superseded?

A: The DIN EN ISO 15875-3:2004-03 / ISO 15875-3:2003 edition has been listed as withdrawn in some ISO catalogues and national collections and has received amendments over time; a revised consolidated edition at international level (ISO 15875-3) has been published in 2025. Users should reference the latest ISO/CEN edition or national adoption and any applicable amendments when assessing conformity.

Q: Is it part of a series?

A: Yes — ISO 15875 is a multi‑part series covering plastics piping systems for hot and cold water installations; Part 3 specifically addresses PE‑X fittings while other parts cover pipes, system design, and supplementary test/technical specifications.

Q: What are the key keywords?

A: PE‑X, fittings, plastics piping, potable water, hydrostatic testing, crosslinking, DIN EN ISO 15875-3, testing and marking.
