1.1. This standard covers two types of methyl ethyl ketone( regular and 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. Methyl ethyl ketone is an organic compound with the formula CH3C(O)CH2CH3 or C4H8O. Its IUPAC1 name is Butan-2-one, it is also known as MEK; 2-Butanone; Methylpropanone; Ethylmethylketone and Methylacetone. NOTE: For the purposes of this Lebanese Standard, the term “wt %” is used to represent the mass fraction 1.2 The following applies to all specified limits in this standard; for purposes of determining conformance with this standard, an observed value or a calculated value shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice ASTM E29. 1.3 The values stated in the International System for measuring units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 For specific hazard information and guidance, see the supplier’s Material Safety Data Sheet for materials listed in this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
