WARNING — It is the purchaser's responsibility to specify the product specification level (PSL),corrosion-resistant alloy (CRA) group, category, grade, delivery conditions and any otherrequirements in addition to those specified herewith to ensure that the product is adequate for theintended service environment. ISO 15156 (all parts) or NACE MR0175/ISO 15156 should be consideredwhen making specific requirements for H2S-containing environment; see Annex G.This International Standard specifies the technical delivery conditions for corrosion-resistant alloy seamlesstubulars for casing, tubing and coupling stock for two product specification levels:- PSL-1, which is the basis of this International Standard;- PSL-2, which provides additional requirements for a product that is intended to be both corrosion resistantand cracking resistant for the environments and qualification method specified in ISO 15156-3 andAnnex G of this International Standard.At the option of the manufacturer, PSL-2 products can be provided in lieu of PSL-1.NOTE 1 The corrosion-resistant alloys included in this International Standard are special alloys in accordance withISO 4948-1 and ISO 4948-2.This International Standard is applicable to the following four groups of product: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 andsuper-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).This International Standard contains no provisions relating to the connection of individual lengths of pipe.NOTE 2 The connection or joining method can influence the corrosion performance of the materials specified in thisInternational Standard.NOTE 3 It is necessary to recognize that not all PSL-1 categories and grades can be made cracking resistant inaccordance with ISO 15156-3 and are, therefore, not included in PSL-2.
