Standard Test Method for Scleroscope Hardness Testing of Carbon and Graphite Materials
N C886
Annotation
This test method covers the apparatus and procedure for determining the hardness of carbon and graphite materials using the Model C-2 scleroscope2with the hammer calibrated for use on carbon and graphite materials with particles smaller than 0.8 mm.3
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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.
