Defines two methods for determining the flowability of fibre-reinforced thermosetting moulding compounds and prepregs. Applicable to all fibre-reinforced thermosetting moulding compounds; differs in the test conditions and apparatus needed.

This International Standard specifies two methods for the determination of the flowability of fibre-reinforced thermosetting moulding compounds and prepregs. The methods apply to ail fibre-reinforced thermosetting moulding compounds and differ in the test conditions and the apparatus required.

The methods may be used to assess the influence of individual components of the moulding compound on the moulding behaviour by determining the flowability of the compound. They are also suitable for quality control purposes, as well as the development of moulding compound formulations.

The major field of application is with moulding compounds based on unsaturated polyester (UP) resins.

Method I is a flowability test carried out at room temperature. Conducting the test at room temperature reduces the effect on the results of changes is the temperature of the moulding compound during the test.

Method II is a flowability test carried out under commonly used moulding conditions. In addition, the plate produced may be used for further testing.
