ISO 13503-2:2006提供了用于评估水力压裂和砾石包装操作中使用的支撑剂的标准​​测试程序。 ISO 13503-2:2006中提到的“支撑剂”是指用于水力压裂和砾石包装操作的砂，陶瓷介质，树脂涂覆的支撑剂，砾石填充介质和其他材料。 ISO 13503-2:2006的目标是为水力压裂和/或砾石填充支撑剂的测试提供一致的方法

ISO 13503-2:2006 provides standard testing procedures for evaluating proppants used in hydraulic fracturing and gravel-packing operations. "Proppants" mentioned henceforth in ISO 13503-2:2006 refer to sand, ceramic media, resin-coated proppants, gravel-packing media and other materials used for hydraulic fracturing and gravel-packing operations. The objective of ISO 13503-2:2006 is to provide a consistent methodology for testing performed on hydraulic fracturing and/or gravel-packing proppants.
