Specifies the method for determining the ability of sheet and strip to undergo plastic deformation in reverse bending. Can be applied to aluminium and its alloys only after previous agreement. The reverse bend test consists of repeated bending through 90 , in opposite directions, of a rectangular test piece held at one end, each bend being over a cylindrical support of specified radius.

WARNING

This document calls for the use of substances and/or procedures that can be injurious to health if adequate safety measures are not taken. This document does not address any health hazards, explosive protection, safety or environmental matters associated with its use. It is the responsibility of the user of this document to establish appropriate health, safety and environmentally acceptable practices.

This document specifies a tensile testing procedure to evaluate the effect of a high-pressure test gas on the materials properties in comparisons to a high-pressure inert gas. It defines the required specimen geometries and the inner surface quality of hollow specimen of metallic materials, filled with a high-pressure-gas. The procedure is intended for screening and characterisation of metallic materials by assessing changes in mechanical properties resulting from various test gases, temperatures, or test pressures. Specific test conditions for tensile testing with high-pressure hydrogen gas are provided in normative Annex A.

ISO 19272:2015 specifies a glow discharge optical emission spectrometric (GD-OES) method for determination of the mass fraction Carbon, Silicon, Manganese, Phosphorus, Sulfur, Chromium, Nickel, Aluminium, Titanium and Copper in low alloyed steels.

The content ranges to which the method is applicable are shown in Table 1.

This document specifies the technical conditions for inspection and delivery of wrought aluminium and wrought aluminium alloy sheet, strip and plate for general applications. It also includes provisions for ordering and testing. It applies to products with a thickness over 0,20 mm up to and including 400 mm. For many special applications of aluminium strip, sheet and plate, specific European Standards exist, where different or additional requirements are formulated and the appropriate alloys and tempers are selected: see Annex A. Most of these special European Standards refer to provisions of this document. The selection of the relevant special European Standards is under the responsibility of the purchaser. Specific European Standards are available for applications involving special properties, such as corrosion resistance, toughness, fatigue strength, surface appearance or welding properties.

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.

This document specifies the technical delivery requirements for open die forgings, forged bars and products pre-forged and finished in ring rolling mills, manufactured from non-alloy quality and special steels and supplied in the normalized, normalized and tempered, quenched and tempered or annealed condition. The majority of steels listed in this document, with properties in the quenched and tempered condition up to 160 mm thickness, are identical to steels specified in EN ISO 683-1 and EN ISO 683-2 and more extensive information on hardenability and technological properties is given in these standards. General information on technical delivery conditions is given in EN 10021.
