Introduction
Australian fire brigade hose couplings evolved independently in each state and territory according to local needs. The various regional connections are subsequently referenced in the appendices of the AS 2419 suite of standards. To facilitate better interagency cooperation, the Australasian Fire and Emergency Services Authorities Council designated the Storz type connection as one of the common Australia-wide fittings for firefighting hoses, equipment, vehicles and fire hydrant installations.
Carl August Guido Storz first patented a quarter turn internal lug two-way hose coupling in Germany in 1881. German fire brigades adopted Storz after a single fire destroyed 203 homes in 1933. The German Institute for Standardization (DIN) describes 25, 52, 75 and 110 mm Storz fittings. The Netherlands Standardization Institute (NEN) also describes 65 mm Storz fittings. Other diameters of Storz connection are variously described by the National Fire Protection Association (USA) and the Standards Council of Canada.
Storz fittings that do not conform to established Standards are not fully compatible with fire brigade equipment and operations. Cast aluminium fittings which are specifically prohibited for firefighting purposes in Australia by AS 2419.2 and AS 2419.3 have been used in place of forged aluminium fittings and have failed. Non-conforming Storz fittings are a safety risk to firefighters and building occupants, especially if connection failure occurs during firefighting and emergency response operations. To address poor conformance and facilitate reliability, this Standard consolidates and specifies the requirements for the standard sizes of Storz fittings used for firefighting purposes in Australia
