According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark,

Introduction
This document establishes a data-block system for the designation of Sheet Moulding Compound (SMC) and Bulk
Moulding Compound (BMC) using a format and coding system established by the International Standards
Organisation (ISO) which is common to most fibre reinforced thermoset and thermoplastic moulding materials. The
system is intended to be applied only to materials ready for commercial use.
The designation system is based on the premise that thermosets and long fibre reinforced thermo-plastics can be
divided into generic families using basic polymers, values of selected designatory properties and additional
qualitative information in order to describe a particular material as precisely as desired.
The system is intended for the designation of a single material (or a small group of similar materials) within a
generic family.
It is not intended to specify by this system the chemical composition or the volumetric recipe of the compound but
to designate the material for identification purposes. It is the responsibility of the producer of the compound
material to provide the appropriate designation.
The data-block system is also the basis for specification given in Parts 2 and 3 of this document.
To 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.

1 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 t
