These test methods cover procedures for assessing the adhesion of coating films to metallic substrates by applying and removing pressure-s 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 Newer Post Older Post Home. Testing of shrinkage for concrete – grout.
ASTM C Standard
I married c10090 30 th June now having one b An exception is made when the options described in the section on test conditions are exercised. 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.
Link to Active This link will always route to the current Active version of the standard. 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 Referenced Documents purchase separately The documents listed below are referenced ashm the subject standard but are not provided as part of the standard. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size.
Historical Version s – view previous versions of standard. The glass plate was removed from the top of the test specimen after 24 h.
Some values have only SI units because the inch-pound equivalents are not used in practice. 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 zstm accordance with ASTM C at 1, 3, 7, 14, and 28 d see figure This thickness was then asfm to the four-reading initial measurement.
The laser approach has been compared with the original setup, and similar results were obtained.
C0190 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.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Combining values from the two systems may result in non-conformance with the standard. The height change of a 3-inch mm -diameter by 6-inch mm -tall cylindrical specimen was measured in accordance with ASTM C The height change results in both test methods are expressed in terms of percentage increase or decrease of the original specimen height.
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. For cementitious grouts, saturate the surface up to SSD. The degree of restraint varies with the mixture viscosity and degree of hardening.
