NVLAP Accredited Certificate
Troemner's NVLAP Accredited Certificate provides compliance in both measurement process and data reported to the customer to meet a variety of standards including NVLAP Handbook 150-2, ISO/IEC 9000, ISO/IEC 17025, FDA, GMP. GLP, DOD, ANSI/NCSL Z540-1 and nuclear requirements. Troemner's NVLAP Laboratory Code is 105013-0. The NIST administered National Voluntary Laboratory Accreditation Program (NVLAP) approves, through periodic audits, all processing and weighing procedures, as well as certificate format and content. Calibration procedures vary by tolerance class requested. For example, for higher accuracy classes such as Troemner UltraClass Series, ANSI/ASTM E617 Class 000, 00, 0 and 1, OIML R 111 Class E0, E1, E2 and F1, Troemner performs a multiple weighing procedure utilizing standards to determine the mass of a customer's weight.Click here to view the sample certificate.
