Difference between a Certificate of Conformance and a Quality Test Certificate
Both can be requested at the time of the instrument purchase. Quality Test Certificates have the values that were obtained at the time of testing. After the instrument has left manufacturing, Quality Test Certificates can only be obtained if the instrument comes back for service to be re-evaluated. Certificates of Conformance state either pass or fail for each test and can be requested any time.
