Plastics. Phenolic resins. Determination of reactivity on aB-transformat ion test plate1 Scope 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.
