Full title and description

STB DIN EN 12094-8 E 2020-11 — Fixed firefighting systems — Components for gas extinguishing systems — Part 8: Requirements and test methods for connectors. This document specifies product characteristics and type-test methods for flexible and rigid connectors used in building-installed gas fire‑extinguishing systems (CO₂, inert gas and halocarbon systems).

Abstract

This standard (prEN / FprEN form adopted as E DIN EN 12094-8:2020-11) defines performance, material and construction requirements and the associated test procedures for connectors (types covering connections between container valves, manifolds and distribution pipework). Key test areas include leakage, burst/pressure resistance, thermal resistance (heat and cold shock where applicable), low‑temperature performance and flexing/fatigue for flexible types. The text is provided in English and German.

Scope

The document applies to flexible and rigid connectors used in fixed gas extinguishing installations in buildings. It covers connectors between storage/container valves and manifolds, connectors for distribution pipework (including connectors intended to accommodate movement), and specifies which connector types require particular thermal, pressure and mechanical tests. The standard is intended for use with CO₂, inert gas and halocarbon agent systems.

Key topics and requirements

• Definition and classification of connector types (e.g., connectors between container valves and manifolds, flexible distribution connectors, rigid connectors).
• Operational reliability requirements and working/maximum service pressures.
• Material specifications for metal parts and corrosion/compatibility considerations.
• Leakage and tightness tests (type tests for sealing performance).
• Resistance to bursting / internal pressure tests and required safety margins.
• Thermal tests: resistance to heat, cold shock and combined pressure/temperature exposure for defined connector types.
• Low‑temperature performance and flexing/fatigue tests for flexible connectors.
• Marking, documentation and manufacturer information requirements.
• Type test methods, sample selection and conformity / AVCP (assessment and verification of constancy of performance) and factory production control expectations.

Typical use and users

Primary users are manufacturers of connectors and pipework components, designers and installers of fixed gas extinguishing systems, testing and certification laboratories, and conformity assessors. Building owners, fire‑safety engineers and authorities having jurisdiction also reference this standard when specifying or approving system components.
