The expiration of a standard depends on several factors, and one of the most significant is the repeated use of the standard over a period of time, which not only increases transpiration rates but also increases the risk of contamination. The one year expiration assigned to a custom product once it leaves our facility is primarily due to the factor above; repeated use by the customer. As long as the lot of custom product is stored under secure, controlled conditions in our facilities its expiration will simply be a function of the date it is shipped to the customer. As for a fixed expiration period over an extended amount of time, it would generally be 36 months following the date of certification. |
