Scleroscope hardness testing of fine-grained carbon and graphite materials

The method covers the apparatus and procedures for determining the hardness of fine-grained carbon and graphite materials using the Shore C-2 Scleroscope with the hammer calibrated for use on fine-grained (particles smaller than 0.8 mm) carbon and graphite materials. The standard includes a discussion of significance, factors affecting reproducibility, apparatus, test specimen, verification of calibration, conditioning, procedure, reporting, precision, and accuracy
