Plastics -- Phenolic resins -- Determination of reactivity on a B-transformation test plate
This standard was last reviewed and confirmed* in 2013.
*Therefore this version remains current
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;
Method B -- flat plate without depressions.
