ABSTRACT
One of the principal motives for making any measurement is to provide objective evidence on which decisions of conformity of entities of any kind (product, service, etc.) to specifications can be based. This chapter deals with decisions of conformity based on measurements specifically with persons, either where measurements are made of a person or where a person can be considered as a measurement instrument. A brief introduction to conformity assessment is followed by two main sections, dealing, respectively, with uncertainty and with the treatment of risk assessment associated with uncertainties when making decisions.
