BS EN ISO 1172:1999

1   Scope 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, tho...
