ASTM D6277 Standard Test Method for Determination of Benzene in Spark-Ignition Engine Fuels Using Mid Infrared Spectroscopy
ASTM D6277使用中红外光谱仪测定火花点火发动机燃料中苯的标准试验方法
Benzene is a compound that endangers health, and the concentration is limited by environmental protection agencies to produce a less toxic gasoline.
This test method is fast, simple to run, and inexpensive.
This test method is applicable for quality control in the production and distribution of spark-ignition engine fuels.
1. Scope
1.1 This test method covers the determination of the percentage of benzene in spark-ignition engine fuels. It is applicable to concentrations from 0.1 to 5 volume %.
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.
