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…
Water quality — Determination of the estrogenic potential of water and waste water — Part 3: In vitr...
This document specifies a method for the determination of the estrogenic potential of water and waste water by means of a reporter gene assay utilizing stably transfected human cells. This reporter gene assay is based on the activation of the human estrogen receptor alpha.
This method is applicable to:
— fresh water;
— waste water;
— aqueous extracts and leachates…
