Annex A (informative) Alternative method of separating chopped
                      glass fibre from mineral filler

Defines two calcination methods for the determination of the textile-glass and mineral-filler content of glass-reinforced plastics; A) For the determination of the textile-glass content when no mineral fillers are present. B) For the determination of the textile-glass and mineral-filler content when both components are present.

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.
