Starting in 2012, at the request of customers, we began offering certification of comparison standards using our SavvyInspector(r) technology. For a very modest fee, we will inspect your comparison standard and provide a report of the scratch brightness and dig sizes, and certify the set against either Army or OEM standard values. All certifications are ISO 17025 and MIL-STD-45662A compliant. Scratch measurements are Army traceable, while dig measurements are NIST traceable.
