ASTM D8235-21

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.

Fuel
This standard is issued under the fixed designation D8235; 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 (´) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 This specification covers requirements for fuel grade ethyl tertiary-butyl ether (ETBE) utilized as a blend component at the
1 % to 22 % by volume for use as automotive spark-ignition engine fuel covered by Specifications D4814 and D8076 as well as
other automotive fuel applications involving ETBE.
1.1.1 Other ETBE grades may be available for blending that are not covered by this specification. Specification D7618 is also
available from ASTM International.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 The following applies to all specified limits in this standard: For purposes of determining conformance with these
specifications, an observed value or a calculated value shall be rounded “to the nearest unit” in the last right-hand digit used in
expressing the specification limit, in accordance with the rounding method of Practice E29. All digits expressed in the specification
limits are to be considered significant digits.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of
regulatory limitations prior to use.
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.
