碳氢化合物液体 手动采样

[中文适用范围]： 本文件规定了获取液态或半液态烃类、储罐残渣和沉积物样品的手动方法，适用于固定储罐、铁路罐车、汽车罐车、船舶和驳船、桶和罐，以及在管道中输送的液体样品的采集。本文件适用于在大气压或接近大气压下储存，或在较高压力和温度下通过管道输送的液态产品（包括原油、中间产品、合成烃和生物燃料）的采样。本文件规定的采样程序不适用于其他国际标准所涵盖的特殊石油产品，如电气绝缘油（见IEC 60475）、液化石油气（见ISO 4257）、液化天然气（见ISO 8943）和气态天然气（见ISO 10715）。本文件所提及的采样方法和采样设备为编写时正在使用的方法和设备。只要新设备能够按照本文件的要求和程序获取样品，就不排除使用新设备。 [外文原描述]： This document specifies the manual methods used for obtaining samples of liquid or semi-liquid hydrocarbons, tank residues and deposits from fixed tanks, railcars, road vehicles, ships and barges, drums and cans, or from liquids being pumped in pipelines. It applies to the sampling of liquid products, including crude oils, intermediate products, synthetic hydrocarbons and bio fuels, which are stored at or near atmospheric pressure, or transferred by pipelines as liquids at elevated pressures and temperatures. The sampling procedures specified are not intended for the sampling of special petroleum products which are the subject of other International Standards, such as electrical insulating oils (covered in IEC 60475), liquefied petroleum gases (covered in ISO 4257), liquefied natural gases (covered in ISO 8943) and gaseous natural gases (covered in ISO 10715). This document refers to methods of sampling and sampling equipment in use at the time of writing. It does not exclude the use of new equipment, provided that such equipment enables samples to be obtained according to the requirements and procedures of this document.
