Class 00
Used as a primary reference for calibrating other reference standards and weights. Class 00 weights are intended to be used in metrology laboratories where the stability of the environment and careful handling are assured. Although very stable, one-piece construction Class 00 weights have no method of adjustment and are not suitable for general laboratory use. Class 00 weight tolerances are equal to OIML R111 Class E1 tolerances and are tighter than Class 0. The uncertainty is guaranteed to be 1/3 of the tolerance. Class 00 is pending approval of ANSI/ASTM E617.
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.
