JJG 2067-2016 《Measuring Instruments for Metallic Rockwell Hardness》 Related products

JJG 2067-2016 "Metal Rockwell hardness tester" applies to the transfer and verification of the value of the metal Rockwell hardness tester with A, B, C, D, E, F, G, H, K, N, T scales. The standard specifies the procedures, methods and measurement uncertainties for transferring Hardness values from national benchmarks to metrology standards and work Measurement appliances. The standard describes in detail the Measurement characteristics and technical indicators of the reference, standard and work Measurement appliances, and serves as the basis for the traceability of metal rockwell hardness values. The verification system table also refers to the relevant metal Rockwell hardness tester and Hardness block standards to ensure the accuracy and Reliability of the verification process. This standard applies to the need for precise measurement and calibrating of metal hardness of materials in quality control and laboratory testing.
