Standard test blocks are non-representative tools, meaning that they are not manufactured from actual parts. Rather, they are a simplified design that contains manufactured discontinuities such as holes, angles, radii and more. Standard test blocks serve the purpose of standardizing and calibrating test equipment to ensure it is functioning properly.

All test blocks ship with a NIST-traceable certification report stating that the block meets applicable specifications.

Optional fitted, wooden storage case also available.
