Standard Guide for Universal Oxidation/Thermal Stability Test Apparatus
N D4871
Annotation
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.
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.
*A Summary of Changes section appears at the end of this standard.

Типичный Гид для Универсального Прибора Испытания Оксидирования/Термоустойчивости
Это руководство покрывает аппарат, используемый для измерения оксидирования или термической устойчивости жидкостей путем подчинения их температурам в диапазоне от 50 до 375°C в присутствии воздуха, кислорода, азота или других газов в скоростях потока жидкости 1.5 к 13 L/h, или в отсутствие потока газа. Устойчивость может быть измерена в присутствии или отсутствии воды или разрешимых или нерастворимых катализаторов. Развитым газам можно позволить выйти, сжать и собрать, или сжать и возвратить к тестовой ячейке.
