This practice describes how todevel

4、op real time aging data for gloves that are part of finishedgoods inventory (including gloves that may no longer bemanufactured) in order to verify the estimated expiration date(see Note 1). Manufacturers may use this data as a startingpoint for real time aging studies as described in PracticeD7160.

Acceptance Criteria8.1 Glove samples must meet the requirements of theappropriate ASTM product specifications with respect to waterleak testing and “before aging” physical properties.8.2 Sterile product p

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

20、est storage period of the three (3)test lots. 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
