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.
GLP, DOD, ANSI/NCSL Z540-1 and nuclear requirements
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
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
This class is used as a reference standard for calibrating other reference standards and weights and is appropriate for calibrating high-precision analytical balances with a readability as low as 0.01 mg
Troemner's NVLAP Laboratory Code is 105013-0
