Annotation

This document specifies two calcination methods for the determination of the textile glass and mineral filler content of glass-reinforced plastics:
- Method A: for the determination of the textile glass content when no mineral fillers are present.
- Method B: for the determination of the textile-glass and mineral-filler content when both components are present.
This document is applicable to the following types of material:
- prepregs made from yarns, rovings, tapes or fabrics;
- SMC, BMC and DMC moulding compounds;
- textile-glass-reinforced thermoplastic moulding materials and granules;
- filled or unfilled textile-glass laminates made with thermosetting or thermoplastic resins.
The methods do not apply to the following types of reinforced plastic:
- those containing reinforcements other than textile glass;
- those containing materials which do not completely burn off at the test temperature (for example, those based on silicone resin);
- those containing mineral fillers which degrade at temperatures below the minimum calcination temperature
