Abstract
A process for testing the properties of a rubber sample is provided. This process is suitable for use with current rheometers, curemeters, viscometers, and the like, wherein it is common to change test conditions during the duration of the test, when the rubber sample scorches or reaches full cure. This process provides a method for determining an optimal time for changing the test conditions to which the rubber sample is subjected. With this process specifying times for changing test conditions is no longer required prior to starting the test. Rather, the variable test condition is changed at sample-specific times that closely coincide with the actual scorch time or full cure time of the sample.
