WebIn the UK, British Standards govern the gauge block grades through BS 4311: Part 1: 1993. It has four grades: K, 0, 1, and 2 that regulate up to 4 inches or 100 mm of the gauge block length. BS (in the United Kingdom) regulates the grades based on: Tolerance on central length’s deviation from the nominal. csonline agentura-cas.cz
