Welding — Determination of Ferrite Number (FN) in austenitic and duplex ferritic-austenitic Cr-Ni st...
This document specifies the method and apparatus for:
— the measurement of the delta ferrite content, expressed as Ferrite Number (FN), in largely austenitic and duplex ferritic-austenitic stainless steel[1] weld metal through the attractive force between a weld metal sample and a standard permanent magnet;
— the preparation and measurement of standard pads for manual metal arc…
Alloyed steels — Determination of manganese — Potentiometric or visual titration method
This document specifies a potentiometric or visual titration method for the determination of manganese content in alloyed steels.
The method is applicable to manganese mass fractions between 2 % and 25 %. Vanadium and cerium interfere with the determination. If the mass fraction of cerium in the sample is less than 0,01 %, or the mass fraction of vanadium in the sample is less than 0,005 %, the…
Water quality — Determination of the estrogenic potential of water and waste water — Part 2: Yeast e...
This document specifies a method for the determination of the estrogenic potential of water and waste water by means of a reporter gene assay with a genetically modified yeast strain Arxula adeninivorans. This reporter gene assay is based on the activation of the human estrogen receptor alpha.
Arxula adeninivorans is a highly robust and salt- and temperature-tolerant test organism and is…
Vegetable fats and oils — Determination of composition of triacylglycerols and composition and conte...
This document specifies the determination of composition of triacylglycerols and the determination of the composition and content of diacylglycerols by capillary gas chromatography in vegetable oils with a lauric acid content below 1 %.
Applying certain technological processing 1,2-diacylglycerols (1,2-DAGs) are transformed to the more stable isomeric 1,3-diacylglycerols (1,3-DAGs) due to acidic…

Welding and allied processes — Determination of hydrogen content in arc weld metal
This document specifies the sampling and analytical procedure for the determination of diffusible hydrogen in martensitic, bainitic, and ferritic steel weld metal arising from the welding of such steels using arc welding processes with filler material.
The techniques specified in this document include collection of diffusible hydrogen via displacement of mercury or collection into a headspace…
