【英文标准名称】: Guide for Universal Oxidation/thermal Stability Test Apparatus 【原文标准名称】: 通用氧化/热稳定性测试仪器指南 【标准号】: ANSI/ASTM D4871-2006 【标准状态】: 作废 【国别】: 美国 【发布日期】: 2006 【实施或试行日期】: 2006-05-24【发布单位】: 美国国家标准学会(US-ANSI)【起草单位】: ANSI【标准类型】: ()【标准水平】: ()【中文主题词】: 检验设备;导则;热稳定性【英文主题词】: Checking equipment;Guidelines;Testing devices;Thermal stability【摘要】: 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.【中国标准分类号】: N51【国际标准分类号】: 19_040【页数】: 【正文语种】: 英语
