Imagine two different first-party labs, in different factories, each of which carries out sampling in the respective production line of its factory and then analyses those samples, being both accredited for the two activities. Now, according to the DIS, they will have to evaluate sampling uncertainty, as well as that for the actual measurement.
Then, one of those two labs has the “clever” idea of making an arrangement with the production manager so, from now on, the production department is to do the sampling and then take the samples to the lab to be analysed. So, this lab can claim it doesn´t carry out sampling, thus it isn´t compelled to evaluate sampling uncertainty and simply continues evaluating measurement uncertainty.
Meanwhile, the other lab, which continues to carry out its sampling, is now compelled to evaluate them both. Do you get the picture? Isn´t this unfair?
“Isn´t this some kind of discrimination?”
Hope you get now my point.
