NOTE: All Symbols and their description

* : Meaurement Capability is expressed as an uncertainty (±) at a Confidence probability of 95 %

$ : Only in Permanent Laboratory

♣ : Only for Site Calibration

# : The laboratory is also capable for site calibration however, the uncertainty at site depends on the prevailing actual environmental conditions and master equipment used

Φ : Laboratory can also Caibrate instruments/devices of coarser resolution/ least count within the accredited range using same reference standard/ master equipment under the scope of accreditation
