Plastics — Phenolic resins — Determination of the pseudo-adiabatic temperature rise of liquid resols when cured under acid conditions

Cancels and replaces the first edition (1989). Specifies a method for determining the exothermic reactivity of thermosetting liquid phenolic resins when mixed with an acid hardener under specified conditions. The results of the determination are used as a means of assessing the behaviour of the resin during processing.
