I need some explanation if someone can help please.
ISO/IEC 17025:2005 clause 5.10.4.2 "When statements of compliance are made, the uncertainty of measurement shall be taken into account" . What is the interpretation, let's say I have CMM uncertainty .040mm and I am measuring feature that has tolerance +/- .015 deviate .008 from the nominal. Customer remeasure the same feature and result is .042 mm.
Now
#1 Is it appropriate for my lab to make a statement that can hold +/-.015mm tolerance when CMM uncertainty is .040 mm?
#2 Can I tell the customer that should take into account the uncertainty for the difference in the results?
#3 If I measure feature with same tolerance and the deviation is .020mm, Would that be acceptable taking into account .040mm my CMM uncertainty?
Any input would be greatly appreciated. Thanks!!!
