The Barcol Impressor is portable and therefore useful for in situ determination of the hardness of fabricated parts and individual test specimens for production control purposes.
This test method should be used only as cited in applicable material specifications.
1.1 This test method covers the determination of indentation hardness of aluminum alloys using a Barcol Impressor, Model No. 934-1.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
Note 1Another model, No. 935, is for use on plastics but is not included in this test method and should not be used for aluminum alloys.
This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
