20、eet 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
21、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 partic
22、ular 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
23、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 a
24、nd to avoid conflicts within the system codes and abbreviations have to be coordinated with ISO/TC 61/SC 1. EN 14598-1:2005 (E) 5 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
25、 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
26、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 requ
27、ired 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. 2 Normative references The following referenced documents are indispensable for

34、l This designation system for EN 14598-1 is based on the following standardized pattern: Designation Description block Identity block European Standard Individual-item number block Number block Data block 1 Data block 2 Data block 3 Data block 4 Data block 5 The designation consists of an optional d
35、escription block, reading “SMC” or “BMC” and an identity block comprising the European Standard number and an individual-item block. For unambiguous coding, the individual-item block is subdivided into 5 data blocks comprising the following information: The first character of the individual-item blo
36、ck shall be a hyphen. The data blocks shall be separated from each other by commas. If a data block is not used, this shall be indicated by an “X“ (=no indication) but only if another block follows. For labelling purposes and if no other blocks follow the comma between block 1 and 2 can be omitted.
37、There is no need to fill in data blocks, if not required. EN 14598-1:2005 (E) 7 Data block 1 : Marking block.
