Annotation of standard text IEC/TS 62607-6-21-ed.1.0 :

IEC TS 62607-6-21:2022 establishes a standardized method to determine the chemical key control characteristics - elemental composition, and - C/O ratio for powders of graphene-based materials by - X-ray photoelectron spectroscopy (XPS). The elemental composition (species and relative abundance) is derived by the elemental binding energy and integral peak area at corresponding portion of XPS spectrum. - The elemental composition refers to main elements in graphene powders, typically including carbon (C), oxygen (O), nitrogen (N), sulfur (S) , chloride (Cl) and silicon (Si). - This document is applicable to graphene powders consisting of graphene, bilayer graphene (2LG), trilayer graphene (3LG), few-layer graphene (FLG), graphene nanoplate (GNP), reduced graphene oxide (rGO), graphene oxide (GO), and functionalized graphene powders. - Typical application areas are the microelectronics and thermal management industries, e.g. batteries, integrated circuits, high-frequency electronics. This document can be used by manufacturers in research and development and by downstream users for product selection.
