The height change results in both test methods are expressed in terms of percentage increase or decrease of the original specimen height.
The height change of a 3-inch mm -diameter by 6-inch mm -tall cylindrical specimen was measured in accordance with ASTM C These test methods cover procedures for assessing the adhesion of coating films to metallic substrates by applying and removing pressure-s I married on 30 th June now having one b The c10090 plate was removed from the top of the test specimen after 24 h. The values stated in each system may not be exact equivalents; therefore, each system shall f1090 used independently of the other.
In both test methods, there is always a certain degree of friction between the specimen’s sides and the inner surface of the metallic mold.
Sieve size is identified by its standard designation in Specification E Newer Post Older Post Home. Testing of shrinkage for concrete – grout.
Two cylindrical specimens with the same dimensions as those used for the ASTM C test method were prepared in which the change in height was measured at four points on the top surface of the specimens using a micrometer in accordance with ASTM C at 1, 3, 7, 14, and 28 d see figure The degree of restraint varies with the mixture viscosity and degree of hardening.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard aatm are not provided as part of the standard.
Some values have only SI units because the inch-pound equivalents astmm not used in practice. The laser approach has been compared with the original setup, and similar results were obtained.
Link to Active This link will always route to the current Active version of the standard. This approach provided more simplicity in the execution of the test, rather than using a projector lamp, magnifying lens, and indicator charts as described in ASTM C see figure This thickness was then added to the four-reading initial measurement.
Combining values from the two systems may result in non-conformance with the standard. After removal, the thickness of the glass plate was measured with a caliper at the points of contact between the glass plate and the micrometer. 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.

ASTM C Standard
Though not recommended by the ASTM standards, and in order to provide the lowest friction possible, an acetate sheet was used in between the test specimen and the mold. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size.
An exception is made when the options described in the section on test conditions are exercised.
