Real Time Stability Study9.1 If product test data meet the acceptance requirements in8.1, then the initial product shelf life, as determined by realtime aging, is that of the short

Assuming there are enough gloves in the test lots tocontinue testing on at least an annual basis, the mature glovestudy may be extended up to a maximum of five (5) years.However, no glove may be labeled with an expiration date ofmore than five (5) years
