*The SCC has elected not to display the “expiry date” on "Frameable" certificates. Instead they have added a clause stating that: “The Validity of this certificate, including the date of last re-accreditation and its expiry can be confirmed by the accompanying Scope of Accreditation document in the Directory of Accredited Laboratories on the SCC website at scc.ca.”
For your convenience, Interweigh Systems  has provided a link to both the “Frameable Certificate" and the "Scope of Accreditation" above.
