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 \u201cbio-based\u201d as derived from biomass and clarifies that \u201c bio-based\u201d does not imply \u201cbiodegradable\u201d. In addition, \u201c biodegradable\u201d does not necessarily imply the use of \u201cbio-based\u201d material.<\/p>\n
