GB/T 231.2-2012 Metallic materials—Brinell hardness test—Part 2:Verification and calibration of testing machines
Abstract
This part of GB/T 231 specifies the inspection and calibration methods for Brinell hardness testers (hereinafter referred to as hardness testers) used to determine Brinell hardness according to GB/T 231.1.
This part is applicable to the direct inspection method for checking the basic functions of hardness testers and the indirect inspection method for comprehensive inspection of hardness testers. The indirect inspection method can be used independently for regular inspections of hardness testers in use.
If the hardness tester is also used for hardness tests by other methods, the hardness tester should be inspected separately for each method.
This part is also applicable to portable hardness testers.
