ASTM E3246-21 The New Standard for Portable Rockwell Testing

Screening Eagle is pleased to announce the portable Rockwell method is officially ASTM-Standardized and fully complies with the ASTM E3246-21.

After testing and verification, the Equotip 550 Portable Rockwell is now one of the few metal hardness testing instruments to deliver at this new standard.

As shown on ATSM.org, this test method covers the determination of the Differential Indentation Depth hardness of metallic materials by the Differential Indentation Depth hardness principle.

The Differential Indentation Depth hardness test is an empirical indentation hardness test that can provide useful information about metallic materials. This information can correlate to tensile strength, wear resistance, ductility, and other physical characteristics of metallic materials, and can be useful in quality control and selection of materials.
