(Test Method)Standard Test Methods for Compressive Creep of Chemical-Resistant Polymer Machinery Grouts
Standard Test Methods for Compressive Creep of Chemical-Resistant Polymer Machinery Grouts
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.
SCOPE
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.
1.2 Test Method A outlines the molding techniques for an unbonded test specimen. Test Method B covers the molding techniques for a bonded test specimen.
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.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

8.1.2 Test Method A— Using an indicating caliper, measure
the thickness of the specimen in four places around the
circumference to the nearest 0.001 in. Record the average of
the measurements as the specimen thickness. The variation in
the four measurements shall not exceed 0.060 in. (1.5 mm).
8.1.3 Test Method B— Using an indicating caliper, measure
the distance between the two plates at four places around the
circumference to the nearest 0.001 in. Record the average of
the measurements as the specimen thickness. The variation in
the four measurements shall not exceed 0.060 in. (1.5 mm).
