Designed for use in calibrating all portable, bench and production Brinell Hardness Testers. Contains five master Brinell impressions. Made from de-carb free tool steel. Meets ASTM E-10 specifications. Aluminum test blocks available for lower hardness ranges
Can be used for Brinell Calibrations HB 200 through HB 500
Each test block contains 5 master Brinell impressions, certified in accordance to ASTM E-10 on equipment calibrated and traceable to NIST. The arithmetic mean of these 5 impressions is inscribed on the block both in BHN Hardness and diameter in millimeters.
To insure uniformity of testing, the master impressions are made by a Brinell tester with oil dampened dead-weight electronically controlled cycle.
Calibrations of master impressions are made with state-of-the-art calibration equipment.
The special grain free polished surface is designed for easy, error-free reading.
