This document provides testing procedures for evaluating proppants used in hydraulic fracturing and gravel packing operations. NOTE Proppants mentioned in this document refer to sand, ceramic, resin-coated, gravel packing proppants, and other materials used for hydraulic fracturing and gravel packing operations. This document supplements API RP 19D, 2nd edition (2021), the requirements of which are applicable with the exceptions specified in this document. This document provides consistent methodology for testing performed on hydraulic fracturing and/or gravel packing proppants. It is not intended for use in obtaining absolute values of proppant pack conductivities under downhole reservoir conditions.

This document specifies the technical delivery conditions for corrosion-resistant alloy seamless products for casing, tubing, coupling stock and accessory material (including coupling stock and accessory material from bar) for two product specification levels: PSL-1, which is the basis of this document; PSL-2, which provides additional requirements for a product that is intended to be both corrosion and cracking resistant for the environments and qualification method specified in Annex G and in the ISO 15156 series or NACE MR0175. This document contains no provisions relating to the connection of individual lengths of pipe. Demonstration of conformance to ISO 15156-3:2020 or NACE MR0175-2021 of material affected by end sizing, connection manufacture or welding operations is outside the scope of this document. This document contains provisions relating to marking of tubing and casing after threading. This document is applicable to the following five groups of products: a)      group 1, which is composed of stainless alloys with a martensitic or martensitic/ferritic structure; b)      group 2, which is composed of stainless alloys with a ferritic-austenitic structure, such as duplex and super-duplex stainless alloy; c)       group 3, which is composed of stainless alloys with an austenitic structure (iron base); d)      group 4, which is composed of nickel-based alloys with an austenitic structure (nickel base); e)      group 5, which is composed of bar only (Annex F) in age-hardened (AH) nickel-based alloys with austenitic structure.
