ISO 10062:2006 specifies tests which are intended to determine the influence of one or more flowing polluting gas(es) at volume fractions less than or equal to 0,000001 on test samples and/or articles of metals and alloys with or without corrosion protection under determined conditions of temperature and relative humidity. These tests apply to metals and their alloys, metallic coatings (anodic and cathodic), metals with conversion coatings, metals with anodic oxide coatings, and metals with organic coatings.

This document specifies the technical delivery conditions for welded cold sized steel tubes of circular cross section with specified outside diameter D ≤ 193,7 mm and of square and of rectangular cross section for precision applications. This document may also be applied to welded cold sized tube with other cross section shapes. Tubes according to this document are characterized by having precisely defined tolerances on dimensions and a specified maximum surface roughness. Typical fields of application are in the automotive, furniture and general engineering industries.

This document specifies requirements for weldable structural steels made of hot finished seamless and high frequency welded hollow sections to be used in the fabrication of fixed offshore structures. The following thickness limitations are given in this standard: - for seamless hollow sections up to and including 65 mm; - for HFW hollow sections up to and including 25,4 mm. Greater thicknesses can be agreed, provided the technical requirements of this European Standard are maintained. This European Standard is applicable to steels for offshore structures, designed to operate in the offshore sector but not to steels supplied for the fabrication of subsea pipelines, risers, process equipment, process piping and other utilities. It is primarily applicable to the North Sea Sector, but may also be applicable in other areas provided that due consideration is given to local conditions e.g. design temperature. NOTE This document has an informative Annex E on the prequalification of steels for fixed offshore structures in arctic areas. Minimum yield strengths up to 770 MPa are specified together with impact properties at temperatures down to -40 °C.

This document specifies technical delivery conditions for flat products of high yield strength alloy special steels. The grades and qualities are given in Tables 1 to 3 (chemical composition) and Tables 4 to 6 (mechanical properties) and are supplied in the quenched and tempered condition. The steels specified in this document are applicable to hot-rolled flat products with a minimum nominal thickness of 3 mm and a maximum nominal thickness of 200 mm for grades S460, S500, S550, S620 and S690, a maximum nominal thickness of 125 mm for grades S890 and S960, in steels which, after quenching and tempering, have a specified minimum yield strength of 460 MPa to 960 MPa.

This document specifies technical delivery conditions for flat and long products of hot rolled weldable fine grain structural steels in the thermomechanical rolled condition in the grades and qualities given in Tables 1 to 3 (chemical composition) and Tables 4 to 6 (mechanical properties) in thickness ≤ 150 mm. The steels specified in this document are especially intended for use in heavily loaded parts of welded structures such as, bridges, flood gates, storage tanks, water supply tanks, etc., for service at ambient and low temperatures.

This document defines terms relating to powder metallurgy. Powder metallurgy is the branch of metallurgy which relates to the manufacture of metallic powders, or of articles made from such powders with or without the addition of non-metallic powders, by the application of forming and sintering processes.

ISO 683-17:2014 specifies the technical delivery requirements for five groups of wrought ball and roller bearing steels: through-hardening bearing steels (steels with about 1 % C and 1 % to 2 % Cr), case-hardening bearing steels, induction-hardening bearing steels (unalloyed and alloyed), stainless bearing steels, and high-temperature bearing steels.
