National Conference of Weights & Measures adds lubricity requirement to 'premium diesel'

NCWM's interim meeting last week approved a 3,100 grams minimum lubricity limit (measured by ASTM D 6078 SLBOCLE test) to its four requirements for "premium diesel." The other requirements are 47 cetane number; low-temp operability (10th percentile temps per ASTM D6468), and thermal stability (80% reflectance on ASTM D6468 test). Final approval could come at NCWM's annual meeting in July.
