BS EN ISO 1172:1999 Textile-glass-reinforced plastics - Prepregs, moulding compounds and laminates - Determination of the textile-glass and mineral-filler content - Calcination methods
This International Standard 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 International Standard 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 are not applicable 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.
For these materials, ISO 11667, Fibre-reinforced plastics —Moulding compounds and prepregs —Determination of resin, reinforcement-fibre and mineral-filler content —Dissolution method, may be used.
