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 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

The method does not apply to particles of a length or diameter less than 3,0 µm or a width smaller than 2,0 µm. If defined by a product standard or agreement between the involved parties for certain special products, inclusions with a width below 2,0 µm can be evaluated by length alone.Inclusions with dimensions exceeding the upper limits in Table 2 are evaluated as be...

This method is widely used to assess the suitability of a steel for a given use. However, since it is difficult to achieve reproducible results owing to the influence of the test operator, even with a large number of specimens, precautions should be taken when using the method.

ISO 2639 defines the case-hardened depth, and specifies methods for the determination of this depth, in steel.
It is applicable to
carburized cases and carbonitrided cases;
parts that, when heat treated to final hardness, have a hardness of less than 450 HV 1 at a distance of three times the case-hardened depth, from the surface.
The case-hardened depth is defined by special agreement where these conditions are not met.

Specifies three procedures for estimating, and rules for expressing, the average grain size of copper and copper alloys consisting principally of a single phase. The comparison procedure (comparing the specimen with a standard chart) is most convenient and is sufficiently accurate for most commercial purposes. In cases of dispute the use of the Heyn or Jeffries procedures (intercept procedure and planimetric procedure, respectively) having higher degrees of accuracy is recommended.
