1.1 This part of this European Standard specifies the minimum requirements for safety and performance of firefighting and rescue service vehicles as designated in EN 1846-1:1998. NOTE 1 Categories and mass classes of these vehicles are given in EN1846-1:1998. Firefighting and rescue service vehicles normally use a commercial chassis-cab or vehicle. A special chassis may be used for specialised vehicles to meet particular requirements. NOTE 2 Both chassis and vehicle are considered to be standard commercially available items when the manufacture rproposes them for sale in all their standard or special versions, on the basis of catalogues distributed via its commercial network, including chassis and vehicles that are manufactured solely for fire service use. Further requirements for aerial appliances are contained within other European Standards (see EN 1777, Hydraulic platforms for firefighting and rescue services - Safety requirements and testing, EN 14043, High rise aerial appliances for fire service use - Turntable ladders with combined movements - Safety and performance requirements and testmethods and EN 14044, High rise aerial appliances for fire service use - Turntable ladders with sequential movements - Safety and performance requirements and test methods). NOTE 3 Additional regulations, not dealt with in this document, may apply in relation with the use of the vehicles on publicroads. For the purpose of this part of this European Standard, the normal ambient temperature range is -15 oC to +35 oC. NOTE 4 In the case of utilisation outside this temperature range, the particular temperature range should be specified by the customer.
