CEN/TC 335/WG 5 develops CEN standards. The scope of work includes: Elaboration of six CEN/TS's: Solid Biofuels - Methods for the determination of: carbon (C), hydrogen (H) and nitrogen (N) content; oxygen (O) content; sulphur (S) content; chlorine (Cl) content; the content of major elements (Al, Si, K, Na, Ca, Mg, Fe, P and Ti); the content of minor elements (As, Ba, Be, Cd, Co, Cr, Cu, Hg, Mo, Mn, Ni, Pb, Se, Te, V and Zn). Currently, there are 11 published standards from this working group.
The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Working Group in CEN is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.
