Standard Guide for
Universal Oxidation/Thermal Stability Test Apparatus1

This standard is issued under the fixed designation D 4871; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the 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 guide describes an apparatus used to measure the
oxidation or thermal stability of liquids by subjecting them to
temperatures in the range from 50 to 375°C in the presence of
air, oxygen, nitrogen, or other gases at flow rates of 1.5 to 13
L/h, or in the absence of gas flow. Stability may be measured
in the presence or absence of water or soluble or insoluble
catalysts. Gases evolved may be allowed to escape, condensed
and collected, or condensed and returned to the test cell.

1.2 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 and health practices and determine the applicability of regulatory limitations prior to use.
