DIN912 M4 screw weights, sample size \(n=10\), weighted on my Sauter L10 which has a declared error of \(e=0.1\rm{g}\) and \(d=0.1\rm{g}\). Conducted at room temperature \(T=21^{\circ}\). I did this on my Sauter scale because it is a direct reading scale making it faster to handle, than my other (more precise) laboratory scales, especially considering the sample size of 10 I’m using here.
Values in between indicators were rounded up to the next higher 10s of milligrams.
