GB/T 1793-2008 in English

《GB/T 1793-2008航空燃料水反应试验法》由TC280（全国石油产品和润滑剂标准化技术委员会）归口，TC280SC1（全国石油产品和润滑剂标准化技术委员会石油燃料和润滑剂分会）执行，主管部门为国家标准化管理委员会。
本标准规定了航空汽油和航空涡轮燃料中水溶性组分的检验以及这些组分对体积变化和油水界面影响的测定方法。本标准采用国际单位制［ＳＩ］单位。
本标准代替ＧＢ／Ｔ １７９３―２０００《航空燃料水反应试验法》，ＧＢ／Ｔ １７９３―２０００ 是等效采用ＡＳＴＭ Ｄ１０９４―９７制定的。
本标准与ＧＢ／Ｔ１７９３―２０００相比的主要变化是：
―――第２章中增加引用标准ＳＨ／Ｔ０６１６。
―――第３章术语和定义中增加了膜、带状物、泡沫、碎片等术语。
―――水反应界面评级由原来的１、１ｂ、２三个级别修改为本标准的１、１ｂ、２、３、４五个级别。

Standard test method for water reaction of aviation fuels

1 Scope

This standard covers the determination of the presence of water-miscible components in aviation gasoline and turbine fuels, and the effect of these components on volume change and on the fuel-water interface.

The values stated in SI units are to be regarded as standard.

This standard may involve hazardous materials, operations, and equipment. 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.
