(Specification)Standard Specification for Refined Benzene-535
Standard Specification for Refined Benzene-535
ABSTRACT
This specification covers a grade of benzene known as refined benzene-535. Different tests shall be performed in order to determine the following properties of refined benzene-535: minimum purity, maximum toluene content, maximum sulfur content, maximum thiophene content, maximum nonaromatic hydrocarbon content, maximum nitrogen content, water content, maximum acid wash color, appearance, maximum color, 1,4 dioxane content, and minimum solidification point with anhydrous basis.
SCOPE
1.1 This specification covers a grade of benzene known as refined benzene-535.
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 standard. No other units of measurement are included in this standard.
1.4 Consult current OSHA regulations, supplier’s Safety Data Sheets, and local regulations for all materials used in this specification.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
