Scope
Specifies a method for the determination of the reactivity of unsaturated polyester resins as characterized by the maximum temperature reached when heated with catalyst in a water-bath at 80 鳦 and by the time taken for the temperatur of the mixture to rise from 65 鳦 to this maximum temperature. As the test results depend very much on the conditions under which the test is carried out, these conditions are described in detail.
