This International Standard specifies methods for the determination of the B-transformation time of phenolic resins at a specified temperature and under specified conditions on a heated test plate.Two methods are described,each with a different test plate:Method A---plate with depressions in the form of segments of spheres;Method B---flat plate without depressions.
