DC Voltage – 30mV, 2.7V, 30V, 300 V, 1000 V
DC Current – 270μA, 1.5 mA, 27mA, 270mA,2.7A, 5A

Delivery – Lab code will be delivered within 7 working days to the participant laboratory

Note: Participation criteria defined above, is based on present NABL practice of ILC, where CMC of reference lab should be superior (smaller measurement uncertainty) than the participant’s CMC. All Participant labs should ensure that the participation criteria have been met while applying for the PT.

The participant lab should not report estimated uncertainty, superior than accredited CMCs for that parameter for PT measurements. If Estimated uncertainty is coarser to accredited CMCs then Estimated uncertainty should be reported by the participant laboratory. 

It is mandatory for Participating Lab. to submit PT measurement results along with the following documents – –

1. Raw data sheet(s) – PDF format

2. Uncertainty Budget Sheet(s) – PDF format

    

   Method used for PT Item measurement should be provided in the Annexure 1 – Result Sheet.
