* : 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
