This specification covers the standard requirements for nitration grade toluene. The material shall be tested and sampled in accordance with standard test methods and practices and shall conform to the following requirements: volume of non-aromatic hydrocarbons; acid wash color; copper strip corrosion; appearance which shall be a clear liquid, free of sediment and haze; color in the platinum-cobalt scale; and distillation range.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers nitration grade toluene.
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 E29.
1.3 Consult OSHA regulations, supplier's Material Safety Data Sheets, and local regulations for all materials used in this specification.
