So, keep them sealed & protected from cuts/abrasions so the seal stays effective, protected from sunlight & in a cool dry location.

After the inspection & test of several sets from their stock (of that exact batch), they then will either provide a new test/insp date (to go thru all that again), and/or provide an assessment notice of their estimated service life. At that point, the procedure is to test a random sampling of that batch to confirm their effectiveness (thats the TEST), and to inspect the packaging to make sure they are still sealed with not cuts or tears in the protective packaging, etc. For that reason, the US Military does not require an exact expiration date on the package, instead opting for the inclusion of both the MFG DATE & INSP/TEST DATE, which is typically a conservative 5 years from the original date of manufacture. * Test Date(s) Information / Details: When vaccum sealed in the heavy green foil w/plastic laminate, these should be good for 10+ years when stored properly.
