Primary Reference Test Blocks
Primary reference test blocks are standardized using primary standardizing machines in accordance with the hardness definition. Usually, the National Metrology Institute (NMI) of a country standardizes the primary reference test...

Secondary Reference Test Blocks
In the United States, and other countries throughout the world, the National Metrology Institutes are usually not the sole supplier of the needed reference standards for that country. Normally, secondary...

Use of Reference Test Block Standards
Rockwell hardness reference test blocks are used primarily for the indirect verification (see 5.2) and daily verification (see 6.2) of a Rockwell hardness machine. Reference test blocks are also useful...

Verifications of Rockwell Hardness Machines
In order to reduce the overall error in a Rockwell hardness measurement, it is important that the different sources of error are identified and the significant error sources be reduced...
