Getting a sticker and a certificate isn't good enough, because it's possible to use a certified instrument in an inappropriate way, or to introduce errors that weren't anticipated.
Figures I had to pick a fight with someone who designs instruments.
Bold/Red is a a very good point, something too little consideration is given to.
We had people bring micrometers to the lab claiming they were inaccurate and 9 times out of 10 we pulled out the gauge blocks and they were spot on. We would follow the user to the workstation and watch them use it incorrectly.
Everyone wants a torque wrench accurate to 1% but then they use it incorrectly, don't let it temperature stabilize, throw it in a drawer or carry it around in their pocket, etc. Many times the limitation is the user, not the instrument.
