Please tell me about the reference standard/working standard during calibrating the hand held tools(vernier, micrometer etc.)
For example during calibrating a vernier, I have checked the flatness of jaws and got some value so then what will be the acceptance criteria for this value.
I have seen JIS B7502,7503 on the web site of some certified Labs. for the calibration of vernier and micrometer. Please explain me this
:) Also if some one can share me the above standard with kind regards
