GB/T 231.2-2012 focus on the inspection and calibrate of metal materials Brinell hardness tester. The standard clarifies the inspection process of hardness gauge before, during and after use, covering the accuracy inspection requirements of key components such as hardness gauge loading system, indenter, reading device, etc. Through standardized operation, to ensure the accuracy and reliability of hardness gauge measurement results, to provide a solid guarantee for metal material brinell hardness test, widely used in metal production, processing, Quality control and other links to ensure that different hardness gauge measurement data have conformity and comparability.
