GB/T 14574-2000声学 机器和设备噪声发射值的标示和验证
本标准规定了有关机器和设备的下列内容： ——噪声发射值的标示； ——技术文件中应提供产品的噪声发射值和与产品有关的声学信息； ——说明了噪声发射值的验证方法。 本标准使用的噪声发射标示值可分为单值噪声发射标示值Ld或双值噪声发射标示值L和KoL是直接测量的噪声发射值，K是与测量有关的不确定度，Ld为L与K之和，由重复测量得到的置信度范围内不可能超过的上限值，Ld对应于GB/T 14573.1中定义的Lc标牌值。 噪声发射值有单值或双值表示形式，可以是单一的A计权声功率级值LWA或指定位置处的A计权发射声压级LpA或C计权峰值发射声压级LpC，peak三者之一表示。也可以使用上述三种量同时表示。一经选定，相关测试规程中K值也就确定。 附录A给出了确定噪声发射标示值的方法。

BS EN 404-2005自救用呼吸保护装置.带口罩组件的防一氧化碳过滤式自救呼吸器
This document refers to filtering devices designed for protection against carbon monoxide (filter self-rescuer). It specifies minimum requirements for filter self-rescuers. This document does not apply to apparatus for work and rescue or to diving apparatus. Laboratory and practical performance tests are included for the assessment of compliance with the requirements.
BS EN 10298-2005岸上和海底管路用钢管和管件.水泥灰浆内衬
This European Standard specifies requirements for cement mortar linings for protecting the internal surface of steeltubes and pipeline components. It also specifies requirements for their application. It is applicable to the linings oftubes that have been welded longitudinally or spirally, seamless tubes and non-alloy steel components used forfluid transportation. This European Standard does not cover in situ applied or rehabilitation linings.This type of lining is used in particular in the transport and distribution, under pressure or by gravity, of waterintended for human consumption and industrial use, and also in fire extinguishing and waste water systems. Thetemperature of the water transported should not exceed 50 °C. Higher working temperature can be used byagreement of the parties.The constituent materials of cement mortar lining, when used under the conditions for which they are designed, inpermanent or temporary contact with water intended for human consumption, shall not change the quality of thatwater to such an extent that it fails to comply with the requirements of European regulations. For this purpose,reference shall be made to the relevant national standards transposing EN standards when available, dealing withthe influence of materials on water quality.
