[中文适用范围]： 本文件描述了用于实验室或现场固定位置的体积测量（容量测量）的设计、使用和校准。 本文件提供了有关标准和非标准措施的指导。 它还涵盖便携式和移动措施。 本文件适用于石油工业；然而，它可以更广泛地应用于其他应用。 本文件不包括用于低温液体的措施以及用于液化石油气（LPG）和液化天然气（LNG）的加压措施。 根据容量和设计，体积测量被分类为测试测量或验证罐。 本文件中描述的量具主要是设计、校准和用于测量量具的体积，该量具在使用前经过指定时间润湿和排水并指定交付。 然而，许多规定同样适用于使用清洁干燥的量具来测量体积并指定用于容纳的量具。 给出了有关通常预期的不确定性和校准规范的指导。 该文件还在附件 A 中提供了参考公式，更广泛地描述了水和其他流体以及用于体积测量的材料的特性。 [外文原描述]： This document describes the design, use and calibration of volumetric measures (capacity measures) which are intended for use in fixed locations in a laboratory or in the field. This document gives guidance on both standard and non-standard measures. It also covers portable and mobile measures. This document is applicable to the petroleum industry; however, it may be applied more widely to other applications. This document excludes measures for cryogenic liquids and pressurized measures as used for liquid petroleum gas (LPG) and liquefied natural gas (LNG). Volumetric measures are classified as test measures or prover tanks depending on capacity and design. Measures described in this document are primarily designed, calibrated and used to measure volumes from a measure which is wetted and drained for a specified time before use and designated to deliver. Many of the provisions, however, apply equally to measures which are used to measure a volume using a clean and dry measure and designated to contain. Guidance is given regarding commonly expected uncertainties and calibration specifications. The document also provides, in Annex A, reference formulae describing the properties of water and other fluids and materials used in volumetric measurement more generally.
