ASTM D5309-08

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.

Cyclohexane 999
This standard is issued under the fixed designation D 5309; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 This specification covers a grade of cyclohexane identified as “cyclohexane 999.”
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 E 29.
1.3 Consult current OSHA regulations, supplier’s Material Safety Data Sheets, and local regulations for all materials used in
this specification.
