This standard specifies the method for determining the polymerization time of phenolic resins. Polymerization time refers to the time for the resin to reach the B state at a specified temperature to indicate its curing speed. This standard applies to alcohol-soluble phenolic resins (resins after dehydration) in the wood industry.
