(Specification)Standard Specification for Xylenes for p-Xylene Feedstock
Standard Specification for Xylenes for <emph type="ital">p</emph>-Xylene Feedstock
ABSTRACT
This specification covers xylenes for p-xylene feedstock. Xylenes for p-xylene feedstock shall conform to the following requirements: p-xylene minimum weight percent, ethylbenzene maximum weight percent, toluene maximum weight percent, C9 and higher boiling aromatic hydrocarbons maximum weight percent, nonaromatic hydrocarbons maximum weight percent, nitrogen maximum weight percent if needed, sulfur maximum content, appearance, chloride if needed, color, and distillation range.
SCOPE
1.1 This specification covers xylenes for p-xylene feedstock. These xylenes typically are extracted from reformate.
1.2 The following applies to all specified limits in this specification: for purposes of determining conformance with this specification, an observed value or 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. The values given in parentheses are for information only.
1.4 Consult current OSHA regulations, suppliers’ Safety Data Sheets (SDS), 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.
