Terminology3.1 DefinitionsFor definitions of terms used in these test methods, see Terminology C904.4. Significance and Use4.1 These test methods provide a means of measuring the total compressive def
9、lection of chemical-resistant, machinery-groutmaterials under a sustained load at the test temperature. Test stress and temperature can be selected to simulate anticipated useconditions. For the purposes of these tests, creep is considered to be the compressive deflection in inches per inch, cm per
10、cminches per inch, which occurs after the initial loading of the specimen at laboratory temperature. The results do not necessarilycorrelate for different specimen thicknesses. No correlation has been established to actual-use conditions.5. Apparatus5.1 Steel Loading PlatesSteel plates, as described
