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 stainless steels with ferritic, martensitic, austenitic and austenitic-ferritic structures.

NOTE The majority of steels listed in this part of EN 10250 are identical to steels specified EN 10088-3 and more extensive information on properties is given in that European Standard.

General information on technical delivery conditions is given in EN 10021.

This International Standard specifies the acceptance criteria for the surface inspection of steel, nickel alloy and cobalt alloy investment castings by visual examination.

NOTE Criteria for special applications such as aerospace are defined in other International Standards.

This international standard specifies the evaluation method of life cycle analysis of ductile iron pipes used for water applications.

Studies on economic and environmental impacts are important for utility decision-makers as they seek to balance fiscal concerns over immediate and long-term needs across acquisition, operations and maintenance, and planned end of life. For authorities and engineers designing pipeline systems, the life cycle cost analysis serves as a tool to study various scenarios to determine the right solution for site-specific conditions and community values, as well as provide the necessary data to support those decisions.

Informative Annexes are included in this standard as a compilation of reference and consensual factors (pumping cost, leakage accident rate, etc.) but it is recommended to use local data when they are known and verifiable.

This International Standard specifies a method for the liquid penetrant inspection of steel castings, whatever

their grade and the casting procedure used to produce them.

This International Standard specifies tool-steel compositions for usable cast shapes in the annealed condition.

NOTE Annex A gives information on ISO grade designation and available UNS numbers which are similar to the ISO grade designation.

This document specifies requirements for the manufacture of two product specification levels (PSL 1 and PSL 2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries.

This document is a supplement to API Spec 5L, 46th edition (2018), the requirements of which are applicable with the exceptions specified in this document.

This document is not applicable to cast pipe.
