Product certification: Users of this European Standard are advised to consider the desirabi
30、lity of independent certification of product conformity with this European Standard based on testing and continuing surveillance, which may be combined with an assessment of the manufacturers quality management system in accordance with EN ISO 9001. All pressure data in this European Standard are gi
31、ven as gauge pressures in bar, unless otherwise stated. NOTE1 bar = 105 N m-2 = 100 kPa.

37、uirements 4.1 General design The component except seals shall be made of metal. Metal parts of the component shall be made of corrosion resistant materials, e.g. stainless steel, copper, copper alloy or corrosion-protected steel (e.g. galvanized steel, cadmium-plated steel). The component shall be d
38、esigned not to restrict flow of the extinguishant. The component shall be specified by the manufacturer for a working pressure of at least 25 bar. The manufacturer shall specify the minimum velocity of the CO2 flow which is necessary for effective operation. Licensed Copy: London South Bank Universi
