Hello to all, I am grateful if someone could clear up a great doubt that I have how to apply the uncertainty. Using one of the methodologies of the approach NorTest in which the six most recent uncertainties use obtained in the tests interlaboratories, for the DBO we have a relative uncertainty of 9.6 %. The doubt that I have if whenever I do DBO's new test the result obtained (for example 100 mg/L) I must multiply it by 9.6 % to obtain the uncertainty of this test. I am grateful for the orientations in the matter.
