Foundrax UKAS-certified Brinell hardness reference blocks are directly traceable to PTB (Physikalisch-Technische Bundesanstalt) in Germany. They conform to ISO 6506 and ASTM E10 and our accredited uncertainty of measurement puts us at the top of the industry.
We were the first manufacturer in the UK to be officially recognised for the manufacture of Brinell hardness reference blocks and continue to lead the field for quality.
These 173cm surface area Brinell test blocks are supplied with marked grids which make them easier to use and give the correct spacing between indentations. A record card is supplied with each block.
We offer Brinell test blocks in a variety of hardness ranges, allowing the user to select a product appropriate to their calibration and verification requirements.
