Textile-glass-reinforced plastics — Prepregs, moulding compounds and laminates — Determination of the textile-glass and mineral-filler content using calcination methods
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.
