IEC TS 62565-1:2023 which is a Technical Specification, defines the system of blank detail specifications for nanomaterials and nano-assemblies as well as final nano-enabled products addressed in the nanomanufacturing value chain. It defines the concepts of blank detail specification (BDS), detail specification (DS) and key control characteristic (KCC). Furthermore, it provides guidelines how to…

This document is applicable to the measurement of the total silicon content in gaseous matrices such as biomethane and biogas. Silicon is present in a gas phase contained predominantly in siloxane compounds, trimethylsilane and trimethylsilanol. The analytical form of the silicon measured in liquid phase after conducted sampling and derivatization procedure is soluble hexafluorosilicate anion…
