1.1This part of prEN 14598 establishes a data block system for the designation of Sheet Moulding Compounds (SMC) and Bulk Moulding Compounds (BMC)1.2The 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.1.3This International Standard is applicable to all SMC and BMC ready for normal use in the form of sheets and bulks.1.4It is not intended to imply that materials having the same designation give necessarily the same performance. This part of prEN 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.If such additional properties are required, they shall be determined in accordance with the test methods specified in part 2 of this International Standard, if suitable. 1.5Whenever general requirement data in the part 3 of this International Standard need to be indicated, this data block system is also the basis for it.1.6To ensure that the meanings of codes remain unambiguous and to avoid conflicts within the system codes and abbreviations have to be coordinated with ISO/TC 61/SC 1.
