Reinforced thermosetting moulding compounds - Specification for Sheet Moulding Compound (SMC) and Bulk Moulding Compound (BMC) - Part 2: Methods of test and general requirements
This part of EN 14598 specifies the methods of preparation of test specimens and the test methods to be used in
determining the properties of Sheet Moulding Compound (SMC) and Bulk Moulding Compound (BMC).
Requirements for handling test material and for conditioning both of the test material before moulding and of the
specimens before testing are found here.
Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the
materials from which these specimens are made are given. Properties and test methods which are suitable and
necessary to characterize SMCs and BMCs are listed.
The properties have been selected from the general test methods in EN ISO 10350-2, Plastics - Acquisition and
presentation of comparable single-point data - Part 2 Long-fibre-reinforced plastics. Other test methods in wide
use for or of particular significance to these compression and injection moulding materials are also included in this
part of EN 14598, as are the designatory properties found in Part 1: Designation.
In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and
conditioning, test-specimens with the dimensions and the test procedures specified herein. Values determined will
not necessarily be identical to those obtained using test-specimens of different dimensions or prepared using
different procedures.

und Konditionierverfahren, Probekörper mit den Maßen und Prüfverfahren anzuwenden, die in der vorliegen-
den Norm festgelegt sind. Die ermittelten Werte werden nicht notwendigerweise mit den Werten übereinstim-
men, die an Probekörpern mit davon abweichenden Maßen oder mit davon abweichenden Verfahren zur
Probekörperherstellung erhalten wurden.

4 Preparation of test specimens
4.1 General
It is essential that specimens are always prepared by the same procedure (either injection moulding or
compression moulding), using the same processing conditions.
The procedure to be used for each test method is indicated in Table 3 (M = injection moulding, Q = compression
moulding).
The material shall be kept in styrene-proof packaging until it is required for use.
4.2 Pre-treatment of the material
Before processing by injection moulding no pre-treatment of the material sample is normally necessary. If a pre-
treatment is required this shall be in accordance with the manufacturer’s recommendations.
Before processing by compression moulding pre-treatment of the material sample in accordance with ISO 1268 is
allowed.
4.3 Injection moulding
Injection moulded specimens shall be prepared in accordance with ISO 1268-10 and/or ISO 1268-11, using the
conditions specified in Table 1.
