ASTM D5211-01 - 10.6.2001
 
1. 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 Consult current OSHA regulations, suppliers' Material Safety Data Sheets (MSDS), and local regulations for all materials used in this specification.
