This part of prEN 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 selection 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 the moulding compounds, the test methods and the test conditions are based on part 2 of this standard. The list of properties is selected, initially, from those general test methods found in ISO 10350-1, Plastics - Acquisition and presentation of comparable single-point data - Part 1 : Moulding materials.
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 standard.
