EN 14598-3:2005 (E) 4 1 Scope This part of EN 14598 specifies the requirements for physical and chemical properties of Sheet moulding Compounds (SMC) and Bulk Moulding Compound (BMC) and compression or injection moulded specimens. The s
19、election in this part is limited to those materials the composition and properties of which are significantly different. Furthermore the selection is limited to those materials which are of more general technical and/or economical importance. The properties which are used for the characterization of
20、 the moulding compounds, the test methods and the test conditions are based on Part 2 of this document. The list of properties is selected, initially, from those general test methods found in EN ISO 10350-2, Plastics - Acquisition and presentation of comparable single-point data Part 2: Long-fibre-r
21、einforced plastics (ISO 10350-2:2001). The moulding compounds are divided into types corresponding to their composition and properties. The designation of the types of moulding compounds is based on Part 1 - Designation of this document. 2 Normative references The following referenced documents are
22、indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 60695-11-10, Fire hazard testing Part 11-10: Test flames 50 W horizontal and vertical

27、 Sheet moulding compounds, bulk moulding compounds and test specimens prepared by compression moulding complying with this document shall meet the appropriate property requirements shown in Table 1 to Table 4. No specific limits are placed on rheological and processing properties. Never the less sui
28、table rheological and processing properties are essential for the satisfactory use of a sheet moulding compound (SMC) and bulk moulding compound (BMC). Appropriate properties shall therefore be specified in any contract. The test method and the test condition shall be as agreed by the interested par
29、ties. In addition, for some applications, it may be desirable for information to be made available on other properties of the moulding compounds, for example: curing time; peak exotherm; flowability. If this is so, these properties and test methods as well as the test conditions to be used shall be
30、agreed by the interested parties. 4.2 Type and content of filler/reinforcement Sheet moulding compounds (SMC), bulk moulding compound (BMC) and test specimens prepared by compression complying with this document shall meet the appropriate nature and form of the filler/reinforcement and its mass cont
31、ent according to its designation (see Part 1, 3.2, of this document). 4.3 Recycling All formulations can contain recycling materials. Some properties may be changing with contents more then 10 %. 4.4 Property data For those moulding compounds complying with this document the mean value for the numbe
32、r of test specimens to be used for each test method shall meet the appropriate requirement listed in Table 1.1 to Table 1.4 for SMC and Table 3.1 to Table 3.4 for BMC of this part. Properties which may be specified are shown in Table 2.1 to Table 2.4 for SMC and Table 4.1 to Table 4.3 for BMC. EN 14
