gage block

[′gāj ‚bläk]
(design engineering)
A chrome steel block having two flat, parallel surfaces with the parallel distance between them being the size marked on the block to a guaranteed accuracy of a few millionths of an inch; used as the standard of precise lineal measurement for most manufacturing processes. Also known as precision block; size block.

National standard for length in Slovenia comprise of 122-piece set of steel gauge blocks, ranging from 0,5 mm to 125 mm and some additional steel gauge blocks of length up to 1000 mm.
This definition is not exactly consistent with the definition of length of gauge blocks described in the American Society of Mechanical Engineers B89.
This extra control, coupled with improved operational procedures, has allowed a faster throughput of gauge blocks and reduced NPL's measurement uncertainty claim to better than half for longer gauge blocks.
Broomfield's tungsten carbide gauge blocks are used by manufacturers - including aerospace engineers, glassmakers and the oil industry - who need to make precision measurements.
The primary issue explored and tested in this investigation is whether traceability to the same source ensures statistical equality between high-precision laboratories making measurements on the same set of gauge blocks or, for that matter, any tool or instrument used for calibration.
