Le présent code d'essai, applicable aux visseuses portatives, décrit les règles d'essai particulières pour la détermination du bruit aérien émis par ces machines, en complément des règles générales spécifiées dans la norme NF S 31-031. Il indique notamment les conditions de fonctionnement de la machine pour les essais et les grandeurs à déterminer.
This International Standard specifies test methods for the measurement, determination and declaration of the noise emission from hand-held non-electric power tools. It prescribes the loading and working conditions under which can be determined the noise emission, under specified load conditions, expressed as the sound power level, andthe emission sound pressure level at the work station under specified load conditions. This International Standard is applicable to typical hand-held non-electric power tools including rotary tools, orbital and random orbital sanders, rotary and non-rotary reciprocating and percussive tools and a variety of assembly tools. It is not applicable to cartridge-operated tools, fastener driving tools (e.g. nailers, staplers) or any tool powered by an internal combustion engine, nor is it applicable to breakers or other power tools which, when placed on the market, are required to meet the provisions of legislation specifying test methods and imposing limits on noise emission from, for example, equipment used outdoors. NOTE The noise code could also be applied to other equipment such as winches, pneumatic motors, auto-feed drills and tappers, pumps, hydraulic motors and screw feed systems, provided their principles of operation were in accordance with those of pneumatic and hydraulic equipment.
