ASTM D 4871 : 2011

CONTAINED IN VOL. 05.02, 2016 Defines an apparatus used to measure the oxidation or thermal stability of liquids by subjecting them to temperatures in the range from 50 degrees C to 375 degrees C in the presence of air, oxygen, nitrogen, or other gases at flow rates of 1.5 L/h to 13 L/h, or in the absence of gas flow.

1.1 This guide covers 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 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 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.
