Steel — Measurement method for the evaluation of hydrogen embrittlement resistance of high strength ...
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…

Soil, treated biowaste, sludge and waste — Digestion of aqua regia soluble fractions of elements
This document specifies two methods for digestion of soil, treated biowaste, sludge and waste by the use of an aqua regia digestion. Digestion with aqua regia will not necessarily accomplish total decomposition of the sample. The extracted analyte concentrations may not necessarily reflect the total content in the sample but represent the aqua regia soluble metals under the condition of this test…
