Accreditation
Authorisation, approval or recognition of meeting a standard
Calibration
A set of operations that establish, under specified conditions, the relationship between values of quantities indicated by a measuring system, or values represented by a material measure or a reference material, and the corresponding values realised by standards
Conformity
Fulfilment by a product, process or service of specified requirements
Conformity assessment
An activity concerned with determining directly or indirectly that relevant requirements are fulfilled
International standard
Standard recognised by an international agreement to serve internationally as the basis for assigning values to other standards of the quantity concerned
International System of Units (SI)
The units of the metric system used universally in science
Legal metrology
Legal metrology comprises all measurements carried out for any legal purpose and includes measurements that are subject to regulation by law or government decree
Measurement
A set of operations having the object of determining a value of a quantity
Metre Convention
The Metre Convention is an international treaty that provides the basis of all international agreements on units of measurement
Metrology
The science of measurement
National standard
Standard recognised by a national decision to serve, in a country, as the basis for assigning values to other standards of the quantity concerned
Pattern approval
Examination of the pattern (design) of a measuring instrument against national or international specifications
Primary standard
A 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
Reference material
A material or substance one or more of whose property values are sufficiently homogeneous and well established to be used for the calibration of an apparatus, the assessment of a measurement method, or for assigning values to materials
Reference standard
A standard generally having the highest metrological quality available at a given location or in a given organisation from which measurements made there are derived
Secondary standard
A standard whose value is assigned by comparison with a primary standard of the same quantity
Traceability
Traceability is the property of the result of a measurement or the value of a standard whereby it can be related to stated references, usually national or international standards, through an unbroken chain of comparisons all having stated uncertainties
Working standard
A standard that is used routinely to calibrate or check material measures, measuring instruments or reference materials
