scope:

Establishes a data block system for the designation of unsaturated-polyester resins (UP-R). The various types of UP-R are differentiated from each other by a classification system based on information about the basic polymer parameters, the possible fillers/reinforcements (type and content), the intended method of processing, any specified properties, and those of the specified properties used specifically for designation purposes (designatory properties). Is appicable to all types of unsaturated-polyester resin for normal use in a liquid state and in a solid state.
