Provides linear, that is, straight-line, calibration functions that describe the relationship between two variables X and Y , namely, functions of the form Y = A + BX. Although many of the principles apply to more general types of calibration function, the approaches described exploit the simple form of the straight-line calibration function wherever possible.

This International Standard specifies the technical delivery conditions for corrosion-resistant alloy seamless tubulars 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 resistant and cracking resistant for the environments and qualification method specified in ISO15156-3 and AnnexG of this International Standard. At the option of the manufacturer, PSL-2 products can be provided in lieu of PSL-1. NOTE1 The corrosion-resistant alloys included in this International Standard are special alloys in accordance with ISO4948-1 and ISO4948-2. This International Standard is applicable to the following four groups of product: group 1, which is composed of stainless alloys with a martensitic or martensitic/ferritic structure; group 2, which is composed of stainless alloys with a ferritic-austenitic structure, such as duplex and super-duplex stainless alloy; group 3, which is composed of stainless alloys with an austenitic structure (iron base); 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. NOTE2 The connection or joining method can influence the corrosion performance of the materials specified in this International Standard. NOTE3 It is necessary to recognize that not all PSL-1 categories and grades can be made cracking resistant in accordance with ISO15156-3 and are, therefore, not included in PSL-2.
