Steel gauge blocks provide ISO and BS standards calibration references

A range of low priced, high quality steel gauge blocks provide references in the setting and calibration of industrial, precision measuring equipment. Supplied to international standards and with optional UKAS (United Kingdom Accreditation Service) calibration certification, the new gauge blocks – designated ‘EuroGrade’ – are available in grades 1 and 2. Grade 1 gauge blocks are produced in accordance with ISO 3650 and BS 4311 Part 3 and are for checking inspection items eg micrometers, dial indicators, etc, within an inspection area. Grade 2 gauge blocks, produced to the same ISO and BS standards, allow slightly wider tolerance deviation for measurement applications in general workshop environments. Produced in both metric and imperial sizes, EuroGrade gauge blocks are produced in wear resistant alloy steel with a hardness of >63 HRC and a high quality, lapped surface finish. They have excellent dimensional stability and provide a coefficient of thermal expansion of 11.5 x 10.
