In July of last year, the National Conference on Weights and Measures (NCWM) voted on, and passed amendments to NIST Handbook 130 (HB-130). Among the approved changes, was amended language to both the Uniform Regulation for the Method of Sale of Commodities and the Uniform Fuels and Automotive Lubricants Regulation sections on Tractor Hydraulic Fluid (THF).
Marketers of tractor hydraulic fluid and buyers should be aware of the changes in that the new regulations took effect January 1, 2020.
