Are the present measurement standards still valid after SI redefinition?

  • Franco Pavese
Discussion Forum


The SI revision potentially places some basic concerns to all users, one being the validity of their present standards under the new definition. The paper compares what is spelled out in the new SI Brochure draft to what should be specified for practical implementation. The result of the analysis is uncertain for some level of implementation and some standards, with, on the other hand, some positive aspects also illustrated in the paper, not always found explicit in the formal texts.
