Features
ASTM E-10
ISO 6506
All of David L Ellis Brinell Test Blocks come with accreditation to applicable standards. We adhere to a strict procedure for the calibration of these blocks, and the accuracy of the tester is maintained using a proving ring and load cell both traceable to N.I.S.T. The readings themselves are done using a stage micrometer also calibrated and traceable to N.I.S.T.
