Gauge blocks (also known as slip gauges) are a system for producing precision lengths. The individual gauge block is a metal or ceramic block that has been precision ground and lapped to a specific thickness. Gauge blocks come in sets of blocks with a range of standard lengths. Blocks can be stacked to make up a desired length. Slip gauges are available in different grades depending on the accuracy required: Grade 0 (used as setting standards in laboratories), Grade 1 (for inspection departments) and Grade 2 (for shop floor). Ceramic slip gauges offer the most accurate and long lasting type of slip gauges because a) they are free from temperature distortion and therefor give them same size regardless of the temperature in the building and b) are free from wear. Steel block, although cheaper, can distort with heat/cold and over time can wear and lose accuracy. Pin gauges are used for checking a known diameter.
