This document specifies the technical delivery requirements for seamless and welded butt-welding fittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of wrought carbon steel without specific inspection requirements. It specifies: a) steel grade and its chemical compositions; b) mechanical properties; c) dimensions and tolerances; d) requirements for inspection and testing; e) inspection documents; f) marking; g) protection and packaging.

This document specifies the technical delivery requirements for seamless and welded butt-welding fittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of austenitic and austenitic-ferritic (duplex) stainless steel without specific inspection requirements. This document specifies: - steel grades and their chemical compositions; - mechanical properties; - dimensions and tolerances; - requirements for inspection and testing; - inspection documents; - marking; - handling and packaging.

This document specifies a method of tensile testing of metallic materials at temperatures higher than room temperature.

This document applies to stress and/or force-controlled thermo-mechanical fatigue (TMF) testing. Both forms of control, force or stress, can be applied according to this document. This document describes the equipment, specimen preparation, and presentation of the test results in order to determine TMF properties.

This document specifies a diantipyrylmethane spectrophotometric method for the determination of titanium in steel and cast iron. The method is applicable to titanium contents between 0,002 % (mass fraction) and 0,80 % (mass fraction).
