One sample may be used for all of the RFG parameters that need to be determined, including RVP. However, because sample handling in the laboratory may affect various reformulated gasoline properties, such as RVP, analyses must be performed in order of sensitivity. As long as RVP is the first laboratory analysis performed on each sample, there is no need to collect a separate sample just for the RVP measurement.(7/1/94)

Should separate samples be collected for RVP analysis?
