New Reference Standards Release Notification Program

The Reference Standards Notification Program can be used to notify you when a new never-before-released Reference Standard becomes available. The Notification Program does not communicate the release of back-ordered items or lot changeovers. To find out when back-ordered items will become available again, please contact customer service at or call +1-301-881-0666 or 1-800-227-8772.

To receive a monthly list of lot changeovers, please subscribe to our free Email Notice.
