Brinell Test Blocks is used to calibrate portable, bench and production Brinell hardness testers. Each Brinell test block is heat treated in a computer-controlled vacuum heat treat furnace to insure maximum consistency and repeatability. They are then blanched; ground, hand lapped and diamond polished providing you with impressions that are easy to read with precision accuracy.

Brinell test blocks are calibrated with five impressions and certified in accordance to ASTM E-10 and ISO 6506 on hardness testers calibrated and traceable to NIST. The arithmetic mean of the five impressions is inscribed on the block both in BHN Hardness and diameter in millimeters. Each test block is calibrated with Tungsten carbide indenters. HB30 designates 3000 kg / 10 mm ball - the most common Brinell scale, HB5 designates 500 kg /10 mm ball and HB15 designates 1500 kg / 10 mm ball.

Final inspection of Brinell test blocks are performed in our state of the art ISO 17025 accredited laboratories. All test blocks are manufactured in accordance with the latest ASTM E10 Brinell revisions. Each test block comes with a long form certificate of calibration verifying the readings and that the test measurement equipment used was calibrated and traceable to NIST. Available in steel or aluminum in hardness ranges of HB75 to HB525. Test block dimensions: Length 6" (15.24 cm), Width 2 ½” (5.08 cm), Thickness 5/8" (1.59 cm)
