EN 1846-2:20013ForewordThis European Standard has been prepared by Technical Committee CEN/TC 192 "Fire service equipment", thesecretariat of which is held by BSI.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by June 2002, and conflicting national standards shall be withdrawn at the latest byJune 2002.This European Standard has been prepared under a mandate given to CEN by the European Commission and theEuropean Free Trade Association, and supports essential requirements of EU Directive(s).For relationship with EC Directives, see informative Annex ZA, which is an integral part of this standard.EN 1846 "Firefighting and rescue service vehicles" is composed of three parts:
Part 1: Nomenclature and designation;
Part 2: Common requirements - Safety and performance;
Part 3: Permanently installed equipment - Safety and performance.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,Switzerland and the United KingdomSIST EN 1846-2:2002



EN 1846-2:20014IntroductionThis part of this European Standard has been prepared as a harmonised standard to provide one means ofconformity with the essential safety requirements of the Machinery Directive and associated EFTA Regulations.This part of this European Standard is a type C standard as stated in EN 1070:1998.The machinery concerned and the extent to which hazards are covered are indicated in the scope of this part ofthis European Standard.This part of this European Standard also deals with the performance requirements which are common to allfirefighting and rescue service vehicles as defined in the scope.The noise test code considered in this part of this European Standard (see annex F) will allow experience to begained in the measurement of noise emission in view of future revisions.1 Scope1.1This part of this European Standard specifies the minimum requirements for safety and performance offirefighting and rescue service vehicles as designated in EN 1846-1:1998.NOTE 1Categories and mass classes of these vehicles are given in EN 1846-1:1998.Firefighting and rescue service vehicles normally use a commercial chassis-cab or vehicle. A special chassis maybe used for specialised vehicles to meet particular requirements.NOTE 2Both chassis and vehicle are considered to be standard commercially available items when the manufacturerproposes them for sale in all their standard or special versions, on the basis of catalogues distributed via its commercialnetwork, including chassis and vehicles that are manufactured solely for fire service use.Further requirements for aerial appliances are contained within other European Standards (see prEN 1777:1994Hydraulic platforms for fire fighting and rescue services - Safety requirements and testing, prEN 14043:2000Automatic turntable ladders for fire service use - Requirements and test methods and prEN14044:2000 Semi -automatic turntable ladders for fire service use - Requirements and test methods).NOTE 3This part of this European Standard should be read in conjunction with any national regulations in force for vehiclesusing the public roads and with any EC Directives and associated EFTA regulations in force relevant to vehicles and theirequipment.For the purpose of this part of this European Standard, the normal ambient temperature range is - 15 °C to + 35 °C.NOTE 4In the case of utilisation outside this temperature range, the particular temperature range should be specified by thecustomer.1.2 This part of this European Standard does not apply to:

vehicles with a gross laden mass not exceeding 2 t;
boats;
aircraft;SIST EN 1846-2:2002

trains;
ambulances;
airport vehicles complying with International Civil Aviation Organisation (ICAO) recommendations.1.3
This part of this European Standard deals with the technical requirements to minimise the hazards listed inclause 4 which can arise during the commissioning, the operational use and the routine checking of firefighting andrescue service vehicles when carried out in accordance with the specifications given by the manufacturer or hisauthorised representative.It does not cover the hazards generated by:
radiation (low frequency, radio frequency, radiation, micro-waves);
errors in the software;
use in potentially explosive atmospheres;
construction, transportation, maintenance and decommissioning;
wind pressure in and out of use;
static electricity problems;
remote control;
electromagnetic compatibility.This part of this European Standard also deals with performance requirements.1.4
