4、reword This standard includes safety requirements. This standard has been prepared by Technical Committee ISO/TC 118 “Compressors, pneumatic tools and pneumatic machines” in collaboration with Technical Committee CEN/TC 255 “Hand-held, non-electric power tools Safety” (Secretariat: SIS, Sweden). The
5、 responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Section Kompressoren und Drucklufttechnik. Amendment of the European Machinery Directive has made it necessary to review the previously valid standard, EN ISO 15744
6、:2002, in terms of the essential requirements of the new European Machinery Directive, 2006/42/EC. This standard concretizes the basic requirements set out in Annex I of the EU Machinery Directive 98/37/EC (valid until 28 December 2009) and the new EU Machinery Directive 2006/42/EC which becomes app
7、licable on 29 December 2009 relating to hand-held non-electric power tools to be placed on the EEA market, with the intent of simplifying the means of proving conformity with such requirements. Once this standard is designated a harmonized standard in the Official Journal of the European Union, a ma
8、nufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (the so-called “presumption of conformity”). The technical substance of the standard has not been changed. The European Standards corresponding to the International Standards referred to in claus
9、e 2 and the bibliography of the EN are given in Annex NA, whereby DIN EN or DIN EN ISO Standards are only listed if these have not been published as DIN EN or DIN EN ISO Standards with the same number.

Introduction The noise test code presented by this International Standard gives methods for determining and declaring the noise
34、emission values of hand-held non-electric power tools: i.e. the total noise level from the power tool expressed as sound power level and as the emission sound pressure level at the work station. These methods have been designed to give results that make it possible to compare the acoustic performanc
35、e of various power tools. The power tools are either run at no load, when this gives a representative value, or in an on-load condition but with the process noise muffled so that it is well below the noise level of the power tool. The methods were chosen to give a satisfactory reproducibility of res
36、ults and are based on present practice in industry. For many power tools in a real work situation the noise from the process dominates the total noise emission in actual use. The process noise varies within very wide limits and cannot be predicted. Users are cautioned that the emission sound pressur
37、e level as determined by this code may not be representative of actual operator exposure levels, which are unique characteristics of individual applications and environmental factors beyond the control of the manufacturers of the equipment covered by this International Standard, and are under the ex
38、clusive control (and therefore the responsibility) of the users of the equipment. This International Standard was prepared with the assistance of both PNEUROP, the European body representing manufacturers of compressors, vacuum pumps, pneumatic tools, pneumatic machines and allied equipment, and CAG
39、I, the compressed air and gas institute, in the United States. 4 DIN EN ISO 15744:2008-11 EN ISO 15744:2008 (E) 1 Scope This International Standard specifies methods for the measurement, determination and declaration of the noise emission from hand-held non-electric power tools. It prescribes the lo
40、ading and working conditions under which can be determined a) the noise emission, under specified load conditions, expressed as the sound power level, and b) the emission sound pressure level at the work station under specified load conditions. This International Standard is applicable to typical ha
41、nd-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
42、 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 This noise meas
43、urement 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. 2 Normative references The
