Plastics — Phenolic resins — Determination of reactivity on a B-transformation test plate

ISO 8987:2005 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;
