On-Demand Calibration PT Schemes

Laboratories that wish to participate in schemes that are not available in the plan for the Scheduled Calibration PT Schemes and are available as “On-Demand Calibration PT Schemes” can find the details in the table below.

The costs of these are dependent on a number of factors and you are encouraged to contact the NLA – SA office for a quotation.

Application Form

In order to register for any scheme please download the Calibration PT Application Form, complete and submit one form per scheme.
