This specification covers commercial hexanes used in the preparation of adhesives, coatings, and printing inks, as raw materials in chemical synthesis, and as solvents in various kinds of extraction operations. The commercial hexanes should conform to the specified requirements for aniline point, apparent specific gravity, bromine index, color Pt-Co, distillation range, kauri-butanol value, nonvolatile matter content, odor, sulfur content, and benzene content.

1.1 This specification covers the range of products commonly referred to as hexanes, which find uses in the preparation of adhesives, coatings, and printing inks, as raw materials in chemical synthesis operations, and as solvents in various kinds of extraction operations.

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 E 29.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.

1.4 For specific hazard information and guidance consult supplier's Material Safety Data Sheet.
