Assessment and use of measurement uncertainties in legal metrology

As legal metrology is first and foremost metrology, you are invited to treat the calculation of uncertainty in the same way as in industrial metrology, i.e. by drawing up a list of the influencing quantities (Ishikawa 5M diagram, for example), carrying out a complete description of the measurement model, establishing a justified and documented uncertainty budget, and indicating an announced uncertainty with a mentioned enlargement factor.
