scope:

This part of EN 14598 establishes a data block system for the designation of Sheet Moulding Compounds (SMC) and Bulk Moulding Compounds (BMC) The types of SMC and BMC are differentiated from each other by a classification system based on information about basic polymer parameters, fillers/reinforcement content and type, intended method of processing and/or manufacturing, specific characteristics and designatory properties. This document is applicable to all SMC and BMC ready for normal use in the form of sheets and bulks. It is not intended to imply that materials having the same designation give necessarily the same performance. This part of EN 14598 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. Whenever general requirement data in the part 3 of this document need to be indicated, this data block system is also the basis for it.
