Reference measuring equipment shall be calibrated and traceable to a recognised national or international Standard and records maintained.
I'm wondering what standard people are following in the U.S.
We check weigh scales daily and they have certain variances they must fall under but we are not following any particular standard and I'm having a tough time finding a standard or law that states rules for scales and/or the weights(certified by state office) that verify the scales are reading correctly.
I'm not in USA but I'm predicting NIST will come up as a primary reference standard. I believe they offer a free download of their expectations.
