1.1 本试验方法涵盖了评定燃气轮机燃料在燃料系统内沉积分解产物的趋势的程序。 1.2 以毫米汞柱为单位的压差值仅根据本试验方法定义。 1.3 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.4 警告 -许多监管机构已将汞指定为可导致中枢神经系统、肾脏和肝脏损害的危险物质。 汞或其蒸汽可能对健康有害，并对材料具有腐蚀性。处理汞和含汞产品时应小心。有关详细信息，请参阅适用的产品材料安全数据表（MSDS）和EPA网站-http://www.epa.gov/mercury/faq.htm-了解更多信息。用户应意识到，法律可能禁止向您所在的州或国家销售汞和/或含汞产品。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 有关特定警告声明，请参阅 6.1.1 , 7.2 , 7.2.1 , 7.3 , 11.1.1 和 附件A5 . ====意义和用途====== 5.1 测试结果表明燃气轮机运行期间的燃料性能，并可用于评估液体燃料接触规定温度下受热面时形成的沉积物水平。

1.1 This test method covers the procedure for rating the tendencies of gas turbine fuels to deposit decomposition products within the fuel system. 1.2 The differential pressure values in mm Hg are defined only in terms of this test method. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 WARNING —Mercury has been designated by many regulatory agencies as a hazardous material that can cause central nervous system, kidney and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury containing products. See the applicable product Material Safety Data Sheet (MSDS) for details and EPA’s website—http://www.epa.gov/mercury/faq.htm—for additional information. Users should be aware that selling mercury and/or mercury containing products into your state or country may be prohibited by law. 1.5 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. For specific warning statements, see 6.1.1 , 7.2 , 7.2.1 , 7.3 , 11.1.1 , and Annex A5 . ====== Significance And Use ====== 5.1 The test results are indicative of fuel performance during gas turbine operation and can be used to assess the level of deposits that form when liquid fuel contacts a heated surface that is at a specified temperature.
