Significance and Use
4.1 These test methods provide a means of measuring the total compressive deflection of chemical-resistant, machinery-grout materials under a sustained load at the test temperature. Test stress and temperature can be selected to simulate anticipated use conditions. For the purposes of these tests, creep is considered to be the compressive deflection in inches per inch, which occurs after the initial loading of the specimen at laboratory temperature. The results do not necessarily correlate for different specimen thicknesses. No correlation has been established to actual-use conditions.
1.1 These test methods cover a quantitative, comparative test for compressive creep of chemical-resistant grouting materials under a sustained load at a test temperature. Constant load is maintained using a bolt and spring washers. Measurements are made at laboratory temperature after exposure periods at the selected test temperature.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
