Full title and description
DVGW-Arbeitsblatt W 534:2015-07 — "Rohrverbinder und Rohrverbindungen in der Trinkwasser-Installation" (English title: "Pipe connectors and pipe joints in drinking water installation"). The document is a DVGW technical rule (Prüfgrundlage/Arbeitsblatt) that specifies requirements and test procedures for pipe connectors and joints used in potable water installations.
Abstract
This Prüfgrundlage defines requirements, test methods and acceptance criteria for pipe connectors and pipe joints intended for drinking-water installations in buildings (within the scope of DIN 1988/TRWI). It covers materials, sealing elements, mechanical and leakage tests, marking and documentation necessary to demonstrate suitability for potable-water use. The 2015 edition supersedes earlier versions and consolidates test requirements relevant to modern connector types (press, push-fit, compression, welded and similar systems).

Scope
The standard applies to connectors and joints for pipes used in drinking-water installations within buildings and associated premises, following the application area of DIN 1988 (TRWI). It sets out test bases and acceptance criteria to ensure mechanical integrity, leakage tightness and hygienic suitability of connectors and joints across common pipe materials (metallic and polymeric). It is intended for components that remain in service as part of the potable-water distribution system.
Key topics and requirements
- Definition and classification of pipe connectors and joint types (press, compression, welded, push-fit, mechanical couplings).
- Material and elastomer compatibility requirements for potable water (hygiene and ageing behaviour; references to DVGW W 270 / KTW material guidance where applicable).
- Test procedures: leakage tests, internal pressure/cyclic pressure tests, mechanical strength and pull‑out tests, corrosion-resistance checks and dimensional verifications.
- Acceptance criteria and conformity assessment for installation and factory documentation, marking and traceability.
- Reference and alignment with DIN 1988 (TRWI) requirements for drinking‑water installations and related product standards for fittings.
Typical use and users
Used by manufacturers of pipe fittings and connectors, testing and certification laboratories, installers (sanitary/plumbing contractors), building services engineers, product approval authorities and specifiers involved in potable-water system design and compliance. The document is used to design, test and assess connectors for compliance with recognized technical rules for drinking-water installations.
Related standards
Closely related to DIN 1988 (TRWI — technical rules for drinking-water installations) and other DVGW/WVGW rules and product standards such as DVGW W 270 (requirements for elastomers/materials for potable water), DVGW W 531/W 532 (related connector/worksheet history) and relevant DIN/EN product standards for fittings (e.g., DIN EN and DIN standards for metallic and polymer fittings). Users should consult the TRWI and specific material/product standards when applying W 534.
