The Triple Safety Standard is an innovative test designed to assess the safety parameters of an attack hose. The test goes beyond the normal criteria for flame resistance and withstanding impact, replicating real world firefighting use and putting end user safety first.
Flame Resistance Test
An ‘Attack’ hose should withstand direct contact with hot embers and flames whilst engulfed in a ‘Class A’ wooden pallet fire, consisting of a minimum of 5 EUR size pallets and
generating temperatures above 850°C, for a period greater than 1 hour; whilst in the flowing condition of 60 LPM and an operating pressure of 7 bar; without leakage or burst.
Following the ‘Class A’ wooden pallet fire test the hose should be capable of withstanding direct impact from falling building materials whilst pressurised; without leakage or burst. The charred section of the hose should be laid on a concrete slab and pressurised to 7 bar.
Firstly, a grade C24 softwood timber beam with cross-section 150mm x 47mm and length 2.4m should be held vertically at a distance of 1.5m from the hose and allowed to fall onto the hose such that the 47mm side impacts the hose. Secondly, a concrete block with a
compressive strength of 7.3N/mm2, measuring 440mm x 215mm x 140mm and weighing 17.4kg should be dropped from a height of 1m directly onto the hose.
To perform as a flexible lay-flat hose in accordance with major international hose standards in terms of burst and working pressure, kink resistance, bend radius, and coil ability.
