Participation Criteria – The participating Laboratory should have Estimated Uncertainties > 0.058% to 0.012% for DC Voltage | 0.106% to 0.028% for DC Current | 0.077% to 0.018% for AC Voltage | 0.139% to 0.091% for AC Current

Delivery – Lab code will be delivered within 7 working days

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. 

Registration- Open*(This PT Item has waiting period of 4-6 months due to more no. of participants)
