ISO 13503-2:2006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。 ISO 13503-2:2006中提及的“支撑剂”指用于水力压裂和砾石填充作业的砂、陶瓷介质、树脂涂层支撑剂、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试验提供一致的方法。

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.
