3、*1.1 These test methods cover two procedures for measuringthe consistency of small samples of lubricating greases bypenetration of a14-scale cone or a12-scale cone.These testmethods include procedures for the measurement of unworkedand worked penetrations.1.2 Unworked penetrations do not generally r
