IEC 61315 pdf download Calibration of fibre-optic power meters
1 scope
This international standard is applicable to instruments measuring radiant power emitted fromsources which are typical for the fibre-optic communications industry. These sources includelaser diodes,light emitting diodes (LEDs) and fibre-type sources. The radiation may bedivergent or collimated. The standard describes the calibration of power meters to beperformed by calibration laboratories or by power meter manufacturers.

3Terms and definitions
For the purposes of this International Standard, the definitions contained in IEC 61931 and thefollowing definitions apply.
3.1
accredited calibration laboratory
a calibration laboratory authorized by the appropriate national organization to issue calibrationcertificates with a minimum specified uncertainty，which demonstrate traceability to nationalstandards
3.2
adjustment
set of operations carried out on an instrument in order that it provides given indicationscorresponding to given values of the measurand
[IEV 311-03-16; see also VIM 4.30]
NOTEWhen the instrument is made to give a null indication corresponding to a null value of the measurand, theset of operations is called zero adjustment
3.3
calibration
set of operations that establish, under specified conditions, the relationship between the valuesof quantities indicated by a measuring instrument and the corresponding values realized bystandards
[VIM,6.11,modified]
NOTE1 The result of a calibration permits either the assignment of values of measurands to the indications or thedetermination of corrections with respect to indications.
NOTE 2 A calibration may also determine other metrological properties such as the effect of influence quantities.NOTE 3 The result of a calibration may be recorded in a document, sometimes called a calibration certificate ora calibration report.
3.4
calibration conditions
conditions of measurement in which the calibration is performed
