Anotace textu normy ASTM D740-11(2019) :

This specification covers two types of methyl ethyl ketone (or 2-butanone), namely: Type I (regular grade) and Type II (urethane grade), that are used primarily as solvents in lacquers and industrial coatings, but also in adhesives, printing inks, lube oil dewaxing, and as chemical intermediates. The physical and chemical properties of methyl ethyl ketone shall conform to the requirements specified for the following: (1) acidity, (2) weight percentage of alcohol, (3) color (Pt-Co scale), (4) distillation range defined by the initial boiling point and dry point, (5) nonvolatile matter content, (6) purity, (7) apparent specific gravity, and (8) weight percentage of water. The sampling and test methods for determining conformance to the specified physical and chemical properties are given.
