Annotation of standard text ASTM D5871-19 :

This specification covers benzene for cyclohexane feedstock. Different tests shall be performed in order to determine the following properties of cyclohexane feedstock: benzene content, sulfur content, thiophene content, toluene plus methylcyclohexane content, methylcyclopentane content, N-hexane content, acid wash color, appearance, color, water content, and solidification point with anhydrous basis.

Keywords:
benzene, cyclohexane feedstock, purity,, ICS Number Code 71.040.01 (Analytical chemistry in general), 71.080.01 (Organic chemicals in general)

Additional information

1. Scope

1.1 This specification covers benzene for cyclohexane feedstock.

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 Safety Data Sheets 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.
