DEFINITION

Classification: 374/16

TRANSFORMATION POINT DETERMINATION (E.G., DEW POINT, BOILING POINT):

(under the class definition) Subject matter for determining the temperature at which a change of state or phase of the test specimen occurs.

(1) Note. The term "change of state" refers to changes between the gaseous, liquids, and solid states.
