DEFINITION

Classification: 374/25

By thermal arrest (e.g., time-temperature curve):

(under subclass 16) Subject matter wherein the transition point is established by locating the temperature at which

there is no temperature change during heating or cooling of the specimen.

(1) Note. The thermal arrest temperature is often located by use of a graph of time vs. temperature during heating or cooling.
