Page 26 DIN 131 9-1 : 1995-01 Explanatory notes Many of the definitions found in this translation have been taken from the Guide to the expression of uncertainty in measurement published by IS0 I and the International vocabulary of basic and general terms in metrology (VIM) 2. The Germ
37、an terms given here are from the original German version of this standard. It should be noted that in DIN EN 45001, the German term Prfung is equivalent to the English concept test (.e. relating to the determination of the characteristics of a product, process or service), while within the context o
38、f quality control, IS0 8402 defines Prfung as being equivalent to the English term inspection (.e. determining the conformity of various characteristics with a requirement). Users of this standard should also note the distinction made between measurement (2.1), testing, inspec- tion(2.1.4), calibrat
39、ion (4.1 O) and verification (examination) (5.13) in the English language, as well as the fact that neither calibration, examination nor verification involve adjustment (4.1 i).
