IEC 61786-1:2013+AMD1:2024 CSV provides guidance for measuring instruments used to measure the field strength of quasi-static magnetic and electric fields that have a frequency content in the range 1 Hz to 100 kHz and with DC magnetic fields to evaluate the exposure levels of the human body to these fields. Sources of fields include devices that operate at power frequencies and produce power…

This document specifies a thiocyanate spectrophotometric method for the determination of molybdenum contents in steel and iron. The method is applicable to molybdenum mass fractions between 0,005 % and 0,125 %. Vanadium and tungsten interfere with the measurement if, because of their contents, the V/Mo ratio is greater than 16 or the W/Mo ratio is greater than 8.

Le présent document spécifie les caractéristiques des fluides neufs à base d’esters de triaryl phosphate utilisés pour la régulation des turbines et pour d’autres systèmes hydrauliques dans les centrales électriques.
