16 PRACTICAL
Candidates will use typical equipment and will inspect wrought cast and weldment samples.
The use of penetrameters, comparators and other control facilities will also be encountered.

17 PRACTICAL SPECIFIC TRAINING
Practical training based on the controlling Specifications, to include control and maintenance checks, (calibration of test pieces, ammeters, plant performance checks, control of detection media etc), current selection with regard to wave form, processing parameters, sequence. This training is to be conducted at the Candidate’s place of work
