本标准提供了评估水力压裂和砾石充填作业中使用的支撑剂的标准测试程序。本标准的目的是为水力压裂和/或砾石充填支撑剂的试验提供一致的方法。制定这些程序是为了提高交付至井场的支撑剂的质量。它们用于评估水力压裂和砾石充填作业中使用的某些物理性质。这些测试应使用户能够比较在所述条件下测试的各种支撑剂的物理特性，并选择适用于水力压裂和砾石充填作业的材料。

This standard provides standard testing procedures for evaluating proppants used in hydraulic fracturing and gravel-packing operations.The objective of this standard is to provide a consistent methodology for testing performed on hydraulic fracturing and/or gravel-packing proppants. These procedures have been developed to improve the quality of proppants delivered to the well site. They are for use in evaluating certain physical properties used in hydraulic fracturing and gravel-packing operations.These tests should enable users to compare the physical characteristics of various proppants tested under the described conditions and to select materials useful for hydraulic fracturing and gravel-packing operations.
