The Webster hardness gage is portable and therefore useful for in situ determination of the hardness of fabricated parts and individual test specimens for production control purposes. It is not as sensitive as Rockwell or Brinell hardness machines; see 10.2.View Less
1.1 This test method covers the determination of indentation hardness of aluminum alloys with a Webster hardness gage, Model B.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.2.1 Exception-The values given in parentheses are for information only.
Note 1-Two other models, A and B-75, are in use, but are not covered in this test method. Model A does not provide numerical values of hardness and Model B-75 covers only a part of the range of interest for aluminum alloys.
1.3 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.
