A NEW TRACEABILITY CHAIN FOR CAPILLARY VISCOMETERS

Valter Y. Aibe, Anderson Ilha

Abstract

A new viscosity traceability chain composed of three capillary viscometers at each chain level is proposed. The correlation matrix between the viscometers at each level can be determined, which enables one to lower the uncertainty relative to the traditional “single-threaded” traceability chain.
