Dear all,
I would like to know what is being explained in Note 2 clause 5.4.5.2 regarding about reference standard and reference materials.
Is it reference standard is a documents like ISO standard or is an object? What actually is a refrence materials? Is it only in calibration that we will use a reference standard and material and not in testing?
Thanks
