ANVIL, USED FOR VERIFICATION OF CALIBRATION CONCRETE HAMMERS - CODE 300-339
Used for the verification of the calibration of the concrete test hammers. Special steel alloy made. Specification requires obligatory the use of the anvil for the hammer tests. The Standard specifies:
• Before a sequence of tests on a concrete surface, take and record readings using the steel reference anvil and check to ensure that they are within the range recommended by the manufacturer. If they are not, clean and/or adjust the hammer.
• After tests, take readings using the steel anvil, record them and compare them with those taken prior to the test. If the results differ, clean and/or adjust the hammer and repeat the test.
