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 E 29.
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.
