MEASUREMENT ACCURACY

Closeness of agreement between a measured quantity value and a true quantity value of a measurand.

 

SYSTEMATIC MEASUREMENT ERROR

Component of measurement error that in replicate measurements remains constant or varies in a predictable manner.

 

RANDOM MEASUREMENT ERROR

Component of measurement error that in replicate measurements varies in an unpredictable manner.

 

CORRECTION

Compensation for an estimated systematic effect.

 

MEASURING INSTRUMENT

Device used for making measurements, alone or in conjunction with one or more supplementary devices.

 

RESOLUTION OF A DISPLAYING DEVICE

Smallest difference between displayed indications that can be meaningfully distinguished.

 

MEASUREMENT STANDARD - ETALON

Realization of the definition of a given quantity, with stated quantity value and associated measurement uncertainty, used as a reference.

 

INTERNATIONAL MEASUREMENT STANDARD

Measurement standard recognized by signatories to an international agreement and intended.

 

NATIONAL MEASUREMENT STANDARD

Measurement standard recognized by national authority to serve in a state or economy as the basis for assigning quantity values to other measurement standards for the kind of quantity concerned..

 

GCP - good clinical practice

Good clinical practice.

 

GLP - good laboratory practice

Good laboratory practice.

 

GMP - good manufacturing practice

Good manufacturing practice.

 

ADJUSTMENT OF A MEASURING SYSTEM

Set of operations carried out on a measuring system so that it provides prescribed indications corresponding to given values of a quantity to be measured.

 

CALIBRATION

Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication.

 

KAZANJE

Vrednost veličine, ki jo daje merilni instrument.

 

INDICATION

Quantity value provided by a measuring instrument or a measuring system.

 

INSPECTION

The procedure, which is found and confirmed that, measuring instrument meets the criterion laid down rules, regulations - national or international (according to SIST EN ISO / IEC 17020).

 

MEASUREMENT UNCERTAINTY

Non-negative parameter characterizing the dispersion of the quantity values being attributed to a measurand, based on the information used.

 

MEASUREMENT ACCURACY

Closeness of agreement between a measured quantity value ana a true quantity value of a measurand.

 

MEASUREMENT

Set of operations to determine the value of quantity.

 

MAXIMUM PERMISSIBLE MEASUREMENT ERROR - NDP

Extreme value of measurement error, with respect to a known reference quantity value, permitted by specifications or regulations for a given measurement, measuring instrument, or measuring system.

 

VERIFICATION

Provision of objective evidence that a given item fulfils specified requirements.

 

MEASUREMENT ERROR

Measured quantity value minus a reference quantity value. 

 

MEASUREMENT REPEATABILITY

Measurement precision under a set of repeatability conditions od measurement.

 

ACCURACY CLASS

Class of measuring instruments or measuring systems that meet stated metrological requirements that are intended to keep measurement errors or instrumental uncertainties within specified limits under specified operating conditions.

 

REFERENCE MEASUREMENT STANDARD

Measurement standard designated for the calibration of other measurement standards for quantities of a given kind in a given organization or at a given location.

 

REFERENCE MATERIAL

Material, sufficiently homogeneous and stable with reference to specified properties, which has been established to be fit for its intended use in measurement or in examination of nominal properties.

 

METROLOGICAL TRACEABILITY

Property of a measurement result whereby the result can be related to a reference through a documented unbroken chain of calibrations, each contributing to the measurement uncertainty.

 

VALIDATION

Verification, where the specified requirements are adequate for an intended use.
