Significance and Use

This method is significant as a process control for polymerization time.

When the cure times are determined at several temperatures and plotted as time versus temperature, different resins can be compared for curing characteristics.

Scope

1.1 This test method covers the determination of the cure rate at any specified temperature for a thermosetting phenol-formaldehyde resin. The time at that temperature required to make a fluid mixture change into a hard immovable mass indicates speed of cure.

1.2 This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
