SURVEILLANCE REQUIREMENTS (Continued) 1.
Confirms the accuracy of the test by verifying that the differ-ence between the supplemental data and the Type A test data is within 0.25 L,.
The formula to be used is:

Has duration sufficient to establish accurately the change in leakage rate between the Type A test and the supplemental test.
