AS 2419.4-2021 PDF

Full title and description

AS 2419.4:2021 — Fire hydrant installations, Part 4: Storz fittings for firefighting purposes. This Australian Standard specifies the design, manufacture, performance and testing requirements for Storz fittings intended for firefighting use, including hose couplings, adaptors, hydrant adaptors, caps, reducers and related components used for connections to valves, hydrant and sprinkler boosters, pipe fittings and branch pipes.

Abstract

The standard sets out mandatory product characteristics (dimensions, materials, coatings, gaskets and marking), performance requirements (pressure tests and interconnection torque), and test methods and quality documentation for Storz assemblies and associated components used in fire hydrant systems in Australia. Appendices provide guidance on quality management, testing procedures and corrosion protection.

Scope

AS 2419.4:2021 applies to Storz fittings intended for firefighting purposes in Australia. It covers the range of Storz assemblies (hose couplings, adaptors with internal and external threads, hydrant adaptors and anti‑tamper plugs, blank and dust caps, reducers, tethers and associated components), defines component dimensions and materials, and specifies manufacturing tolerances, markings and required performance (pressure and interconnection torque) and testing. The standard also includes appendices on quality management, testing and corrosion protection.

Key topics and requirements

• Definitions and application of Storz assemblies for firefighting connections (hose couplings, adaptors, hydrant adaptors, caps and reducers).
• Detailed component dimensions, cam ring and hose tail geometry, retaining rings and gasket types.
• Material specifications and permitted alternative materials (aluminium, brass, stainless steel) and coating/finishing guidance (anodizing, powder coating).
• Manufacturing tolerances, markings and identification requirements for traceability and compatibility.
• Performance requirements including pressure testing and limits, and specified interconnection torque for compatible assemblies.
• Test methods and quality documentation requirements; appendices include recommended testing procedures and quality management guidance.

Typical use and users

Primary users include manufacturers of firefighting couplings and hydrant fittings, building services and fire‑protection engineers, installers and maintainers of fire hydrant systems, fire authorities and certifiers, and testing/calibration laboratories responsible for verifying conformity to the standard. Fire and rescue agencies and enforcement authorities also reference this standard when assessing compatibility and compliance of hose connections.
