ISO 13503-2:2006

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.
