1) In preparation.
(pressure experimentally measured) pressure measured in the extinguisher after stabilisation during at least 24 h at a maximum operating temperature TSmax (≥ 60 °C) and for cartridge operated extinguishers, the maximum pressure shall be the maximum pressure recorded for 0,5 s during a period of 3 min, excluding the first 5 s after releasing the propellant gas 3.2 body shell of the mobile fire extinguisher not fitted with accessories, but fitted with all welded parts 3.3 maximum allowable pressure, PS
(maximum declared pressure) maximum pressure for which the equipment is designed as specified by the manufacturer and which is in any case, greater than or equal to PTSmax 3.4 charge of an extinguisher mass or volume of the extinguishing media contained in the mobile fire extinguisher NOTE For extinguishers expressed as a volume (in litres) for water based extinguishers and as a mass (kilograms) for powder and CO2 extinguishers. 3.5 closure component, other than a safety device or pressure indicator, subject to the internal pressure and used to close off and seal the body

- 25 °C, -30 °C or lower. For water based extinguishers without any protection against freezing. TSmin shall be + 5 °C; TSmax and TSmin claimed by the manufacturer shall be used for the tests. 6.1.2 Requirements After the test described in A.6, the requirements for all extinguishers are as follows:  shall operate satisfactorily;  discharge shall commence within 10 s of the opening of the control valve; cartridge operated extinguishers shall be activated 30 s prior to opening the control valve;  duration of operation shall be according to A.2 and not be less than the value applicable given in Table 4, Table 5, and Table 6;  residual charge remaining in the extinguisher after one single and complete discharge including full decompression shall be as given in Table 7.

It is allowed to reduce the charge of the cylinder by 10 % to avoid overpressure in areas with high ambient temperatures. 6.2.2 Filling tolerances The actual charge of the extinguisher shall be equal to the nominal charge within the tolerances given in Table 2. Table 2 — Filling tolerances on nominal charges Powder Water based CO2 ± 2 % 0 % 0 %
− 5 % − 5 % 6.2.3 Propelling agent Only propellants listed in Table 3 or mixtures thereof, shall be used in extinguishers, whether they are the stored pressure type or cartridge extinguisher type. The maximum proportion of water in mass shall be as specified in Table 3, except when used in stored pressure water based extinguishers. Tracers may be added to the propellant to facilitate leakage detection, but the content shall not exceed 3 % of the propellant content.

% Air 0,006 Argon 0,006 CO2 0,015 Helium 0,006 Nitrogen 0,006 For the charge of the propellant cartridge, the tolerance shall be + 0 %, − 5 % in mass for CO2 and for compressed gases + 0 %, − 5 % in pressure at 20 °C. 6.3 Duration of operation, residual mass and discharge range 6.3.1 Duration of operation 6.3.1.1 Powder extinguishers When determined in accordance with A.2, the duration of operation of powder extinguishers shall be as given in Table 4.
