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.
