This Technical Specification sets requirements for bio-based solvents in terms of properties, limits, application classes and test methods. It lays down the characteristics and details for assessment of bio-based solvents: - fit for purpose in terms of performance related properties; - comply with the requirements regarding the health, safety and environment which apply to general solvents; - are derived from a certain minimum percentage of biomass; and - comply with at least similar sustainability criteria as comparable (regular) solvents. The criteria of the Regulation for Environmental Assessment of Chemicals (REACH) [2] are included in the discussions that have led to this Technical Specification. NOTE – EN 16575 defines the term “bio-based” as derived from biomass and clarifies that “bio-based” does not imply “biodegradable”. In addition, “biodegradable” does not necessarily imply the use of “bio-based” material.
