GB/T 14574-2000聲學 機器和設備噪聲發射值的標示和驗證

本標準規定了有關機器和設備的下列內容： ——噪聲發射值的標示； ——技術文件中應提供產品的噪聲發射值和與產品有關的聲學信息； ——說明了噪聲發射值的驗證方法。 本標準使用的噪聲發射標示值可分為單值噪聲發射標示值Ld或雙值噪聲發射標示值L和KoL是直接測量的噪聲發射值，K是與測量有關的不確定度，Ld為L與K之和，由重復測量得到的置信度范圍內不可能超過的上限值，Ld對應于GB/T 14573.1中定義的Lc標牌值。 噪聲發射值有單值或雙值表示形式，可以是單一的A計權聲功率級值LWA或指定位置處的A計權發射聲壓級LpA或C計權峰值發射聲壓級LpC，peak三者之一表示。也可以使用上述三種量同時表示。一經選定，相關測試規程中K值也就確定。 附錄A給出了確定噪聲發射標示值的方法。

BS EN 10298-2005岸上和海底管路用鋼管和管件.水泥灰漿內襯

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.
