Gauge block sets 150mm 200mm 300mm vernier caliper calibration block
Inspector can join different size together to get different length. We call it wringing. Various grading standards include: JIS B 7506-1997 (Japan)/DIN 861-1980 (Germany), ASME (US), BS 4311: Part 1: 1993 (UK). Tolerances will vary within the same grade as the thickness of the material increases. For inspecting calipers, one should combine block and pin gauge to get more accurate inspection, Especially for length less than 10mm.
