Abstract

CENAM and IBMETRO performed this bilateral comparison in volume of liquids using two 100 ml narrow-neck grinding flasks and a 100 µl piston pipette as part of the measurement assurance program of both laboratories. The volume determination was performed by gravimetric method and uncertainty is estimated by applying the Guide for the expression of the uncertainty of measurements (GUM).
