    Rationale

    Proposal for adding additional reporting requirements to hardness standards when: test results that have been converted from other hardness tests or scales; test results that have been corrected for testing on cylindrical or spherical surfaces. Rationales: Test results that have been converted from other hardness tests or scales: Although ASTM E140 states requirements for reporting converted numbers, there are no comparable statements in the hardness test standards. The E140 requirement may be overlooked or the user may use other hardness conversions. Test results that have been corrected for testing on cylindrical or spherical surfaces: There are no requirements for reporting when corrections are made for tests on curved surfaces. The receiver of test data may not know whether corrections have been made. The difference between an uncorrected test result on a curved surface and the actual hardness can be significant.
