Performance testing (laboratory) Determination of the testing capability of a laboratory, by comparing tests performed between laboratories. |
Preventive measures (opposite of repressive measure) are used for market surveillance and are taken before marketing a measuring instruments, i.e. the instrument has to be type-approved and verified. |
Primary laboratory Laboratory that performs internationally adopted fundamental metrological research and which realises and maintains standards at the highest international level. |
Primary method A method of the highest metrological quality which when implemented can be described and understood completely, and for which a complete uncertainty budget can be provided in SI units, the results of which can therefore be accepted without reference to a standard for the magnitude being measured. |
Primary reference material See reference material, primary. |
Primary standard Standard that is designated or widely acknowledged as having the highest metrological qualities and whose value is accepted without reference to other standards of the same quantity |
Principle of measurement The scientific foundation of a method of measurement. |
Prototype Artefact that defines a unit of measurement. The kilogram prototype (1 kg weight) in Paris is today the only prototype in the SI system. |
