General Information
This document specifies a method for determining the tensile strain hardening exponent n of flat
products (sheet and strip) made of metallic materials.
The method is valid only for that part of the stress-strain curve in the plastic range where the curve is
continuous and monotonic (see 8.4).
In the case of materials with a serrated stress-strain curve in the work hardening range (materials
which show the Portevin-Le Chatelier effect, e.g. AlMg-alloys), the automatic determination (linear

This document specifies a method for determining the ability of metallic materials to undergo plastic deformation in bending. This document applies to test pieces taken from metallic products, as specified in the relevant product standard. It is not applicable to certain materials or products, for example tubes in full section or welded joints, for which other standards exist.

This document gives guidelines for the measurement of hardmetal grain size by metallographic
techniques only using optical or electron microscopy. It is intended for WC/Co hardmetals (also called
cemented carbides or cermets) containing primarily tungsten carbide (WC1)) as the hard phase. It is
also intended for measuring the grain size and distribution by the linear-intercept technique.
This document essentially covers four main topics:
— calibration of microscopes, to underpin the accurac...view more

This document provides a method for the evaluation of the resistance to hydrogen embrittlement (i.e. hydrogen delayed fracture) using constant loading test with hydrogen pre-charged specimens. The amount of hydrogen content absorbed in the specimens is analysed quantitatively by thermal desorption analysis such as gas chromatography, mass spectrometry and so on. In the case of hydrogen continuous charging such as hydrogen absorption in aqueous solution at free corrosion potential, hydrogen absor...view more
