This specification establishes the requirements for p-Xylene. Sampled specimens shall conform to the following physical and chemical properties: minimum purity; maximum m-Xylene content; maximum o-Xylene content; maximum sulfur content; maximum toluene content; maximum ethylbenzene content; maximum nonaromatic hydrocarbons content; appearance; color (Pt/Co scale); distillation range; and maximum pressure.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers high purity p-Xylene.

1.2 The following applies to all specified limits in this specification: for purposes of determining conformance with this specification, 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 standard. No other units of measurement are included in this standard.

1.4 Consult current OSHA regulations, supplier's Material Safety Data Sheets, and local regulations for all materials used in this specification.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
