The Laboratory will issue a list of approved electrodes and combinations of shielding. The Laboratory will include electrodes in the list when certified test data submitted by the manufacturer is found in compliance with the specified requirements. The certification will cover either process qualification or quality control tests. To qualify, such tests must be made within one year before the period covered. For each submission of certified test data, include the manufacturer’s statement that it will advise the Laboratory immediately of any change in materials or processing used in the manufacture of the electrodes made within one year from the date of the tests.

When electrodes to be used are not included in the Laboratory’s list of approved electrodes and combinations of shielding, submit certified test data as described above for each lot showing compliance with the specified requirements.
