Certificate revisions

This page lists revisions of reference material certificates and product information sheets by reference material code in alphabetical order. We notify all customers who bought the materials directly by letter or email of important technical changes like retraction of certified values or revisions of certified values outside the stated uncertainties. We also instruct our authorised distributors to forward this information to their customers.
This page serves as a backup for notifications sent to customers and lists minor editorial changes for which we do not explicitly inform customers. 

The updated versions can be found on the detailed product page (search for the reference material code). The revision date is to the left of the signature of the authorising officer (1st page) underneath the release date of the reference material.

The "letter" contains the link to a copy of the letter we sent to customers in case of important technical changes.

Note that we normally do not send updated certificates. The reason is that our certificates contain the sales date which means that we would have to put on a sales date that is earlier than the revision of the certificate.
