STANDARDS: EN 12504-2, ASTM D5873, C805
Used for the veriﬁcation of the calibration of the hammers.
The EN 12504:2 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.
Made of hardened steel according to the standards.
