This European Standard sets the requirements for bio-based solvents in terms of their bio-based content, their technical properties and test methods. It lays down the characteristics and details for assessment of bio-based solvents that: - are fit for purpose in terms of performance related properties; - comply with the health, safety and environmental requirements which apply generally to solvents; and - are derived from biomass. This European Standard specifies solvent classes, based on the percentage of bio-based carbon content and bio-based content. 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. In addition, this document sets requirements on information to be provided regarding sustainability aspects.
