1.1 本试验方法涵盖有关现场准备、技术程序、质量控制和设备的程序，以指导确定散装材料体积的工作。这些程序包括实用和公认的容量测定方法。 1.2 该测试方法仅允许两种体积计算方法。 1.2.1 轮廓测试方法- 看见 8.1.1 和 9.1 . 1.2.2 横截面试验方法- 看见 8.1.2 和 9.2 . 1.2.3 该测试方法需要对等高线和横截面展开进行直接算子编译。 1.2.4 本试验方法不包括使用数字地形模型软件和程序创建等高线或横截面以进行体积计算。 注1: 成立了一个任务组，以开发数字地形建模（DTM）程序的测试方法。它将解决所有已知的数据收集程序，如传统地面测量、摄影测量、大地定位卫星（GPS）等。 1.3 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 该测试方法审核库存中材料的体积，并与密度值一起用于计算吨位计算值，用于将账面价值与实际库存结果进行比较。本试验方法用于确定煤堆中煤炭或其他材料的体积。

1.1 This test method covers procedures concerning site preparation, technical procedures, quality control, and equipment to direct the efforts for determining volumes of bulk material. These procedures include practical and accepted methods of volumetric determination. 1.2 This test method allows for only two volume computation methods. 1.2.1 Contour Test Method— See 8.1.1 and 9.1 . 1.2.2 Cross-Section Test Method— See 8.1.2 and 9.2 . 1.2.3 This test method requires direct operator compilation for both contours and cross-section development. 1.2.4 The use of Digital Terrain Model software and procedures to create contours or cross sections for volume calculation is NOT encompassed in this test method. Note 1: A task group has been established to develop a test method for Digital Terrain Modeling (DTM) procedures. It will address all known data collection procedures such as conventional ground survey, photogrammetry, geodetic positioning satellite (GPS), and so forth. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This test method audits the volume of material in a stockpile and is used with a density value to calculate a tonnage calculation value used to compare the book value to the physical inventory results. This test method is used to determine the volume of coal or other materials in a stockpile.
