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.
