手持非电动工具.噪声测量代码.工程法(2级

[中文适用范围]： 本国际标准规定了手持式非电动工具噪声发射的测量、测定和声明方法。 它规定了可以确定的负载和工作条件：a）在指定负载条件下的噪声发射，以声功率级表示；b）在指定负载条件下工作站的发射声压级。 本国际标准适用于典型的手持式非电动工具，包括旋转工具、轨道和随机轨道打磨机、旋转和非旋转往复和冲击工具以及各种装配工具。 它不适用于弹头操作工具、紧固件驱动工具（例如钉枪、订书机）或任何由内燃机驱动的工具，也不适用于破碎机或其他电动工具，这些工具在投放市场时需要符合规定测试方法和对室外使用的设备等噪声排放施加限制的立法规定。 注：本噪声测量规范也适用于其他设备，如绞车、气动马达、自动进给钻头和攻丝机、泵、液压马达和螺杆进给系统，前提是它们的操作原理与气动和液压设备的操作原理一致。 。 [外文原描述]： 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, and the 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.
