    Abstract

    This specification covers the requirements for a grade of benzene known as low toluene low dioxane (LTLD) benzene. Sampled materials shall meet specified values of the following physical and chemical properties: purity; toluene content; sulfur content; thiophene content; nonaromatic hydrocarbons content; nitrogen content; acid wash color; color in Pt-Co scale; 1,4 dioxane content; anhydrous basis solidification point; water content; and total chlorides.

    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. Scope

    1.1 This specification covers a grade of benzene known as Low Toluene Low Dioxane (LTLD) Benzene.

    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 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

    1.4 Consult current OSHA regulations, supplier's Material Safety Data Sheets, and local regulations for all materials used in this specification.
