(Specification)Standard Specification for Refined Benzene-545
Standard Specification for Refined Benzene-545
ABSTRACT
This specification covers benzene-545. Tests shall be performed to determine the property requirements of benzene-545 in accordance to the following test methods: benzene weight percentage; sulfur mass; thiophene mass; toluene mass; nonaromatic hydrocarbons weight percentage; nitrogen mass; acid wash color; bromine index, water, appearance, and solidification point.
SCOPE
1.1 This specification covers benzene-545.
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 in 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.
