(Specification)Standard Specification for High Purity p-Xylene
Standard Specification for High Purity <emph type="ital">p</emph>-Xylene
ABSTRACT
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.
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 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.
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.
