NTEP Certificate Status: What is the difference between Active and Inactive? When searching the NTEP Certificate of Conformance (CC) database, one of the selections is labeled "Status”. Additionally, when viewing certificate information, one of the column headings is "Status", with an indication of "Active" or "Inactive" for each certificate. A common question asked of NTEP relates to the meaning of the two terms, active and inactive. These questions have been posed by Weights and Measures regulatory officials, service companies, manufacturers, and certificate holders. What is the difference? Why does it matter? Does inactive status mean the device installed, approved, and in use is no longer traceable to the certificate? Does inactive status mean the certificate is no longer valid? We will answer those questions in this article. The definitions of active and inactive status are found in NIST Handbook 130, Uniform Regulation for National Type Evaluation, Section 2., which defines an "Active Certificate of Conformance" – A document issued based upon testing by a Participating Laboratory, which the certificate holder maintains in active status under the National Type Evaluation Program NIST Handbook 44 (Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices), and test procedures contained in NCWM Publication 14. By maintaining the Certificate in active status, the Certificate holder declares the intent to continue to manufacture or remanufacture the device consistent with the type and in conformance with the applicable requirements.
