Establishes a data block system for the designation of epoxy powder moulding compounds (EP-PMCs). Applicable to all EP-PMCs ready for normal use in the form of powder, granules or ground material. It is not meant to imply that materials having the same designation necessarily give the same performance. It does not provide engineering data, performance data or data on processing conditions which may be required to specify a material for a particular application and/or method of processing.
