In those cases where leaded frits seem necessary, it is recommended to fire to at least cone 03, to ensure sufficient reaction of lead and glaze ingredients.
Experimental study was carried out of the flammability offire retardant imitation oak PVC artificial density board (brand name "White oak board") by means ofCone Calorimeter.
For external radiation ignition manner, a series of small-scale fire tests were conducted in a cone calorimeter in accordance with ISO 5660. Heat release rate and mass loss rate were measured.
