This document specifies the characteristics and their respective measurement methods of graphene-related 2D materials in sheet and particle forms for commercial applications with the aim of classification of the materials. The classification framework consists of the following elements:

a)      

relevant material characteristics for commercial use;

b)      

identification of applicable measurement methods;

c)       

a range of the characteristic measured values when applicable;

d)      

syntax to guide consistent naming and descriptions;

e)      

an applicable technical data sheet template.
