Scope

SN/T 2931-2011 is the English-translated version of 航空涡轮燃料中萘系烃标准试验方法紫外分光光度法.

SN/T 2931-2011 — This standard specifies the spectrophotometric determination UV Aviation Turbine Fuels naphthalene, acenaphthene and their alkyl derivatives (naphthalene hydrocarbons, the same below) containing Method quantity.

This standard applies to the determination of the final boiling point of not higher than 315 °C of aviation turbine fuel volume fraction of not more than 5% of naphthalene hydrocarbon content.

In the laboratory to determine the accuracy of the method, the hydrocarbon concentration naphthalene used in step A sample (volume fraction) in the range of 0.03% ~ 4.25%; the concentration of hydrocarbon naphthalene used in step B sample (volume fraction) in the range of 0.08% to 5.6%.

This standard can be measured may exist in a sample of naphthalene hydrocarbons maximum levels.
