This Standard is applicable to determine the motor gasoline, ester compounds with concentration of 50mg/L ~ 2000mg/L; this Method can also determine beyond such content range; however, the precision is not investigated. This Standard is not applicable to alcohol-containing gasoline; Certain alcoholic compounds (such as methanol, ethanol, tert-amyl alcohol, and sec-butanol) and ketone compounds (such as acetone and butanone) may interfere the determination of ester compounds.

This standard applies to vehicle gasoline, ester compounds measured concentration of 50 mg/L ~ 2000 mg/L, beyond the scope of this method can also be measured by this method, but the precision is not investigated. This standard does not apply to alcohol-containing gasoline. Certain alcoholic compounds (such as methanol, ethanol, t-amyl alcohol and sec-butanol) and ketones (such as acetone and methyl ethyl ketone) may interfere with the determination of vinegar compounds.
