Test methods of propylene oxide for industrial use — Part 1: Determination of purity and trace impurities--Gas chromatography ISO/NP 25095-1

Scope

This document specifies a test method for the determination of propylene oxide and trace impurity in industrial propylene oxide by capillary gas chromatography. This document is suitable for the determination of propylene oxide with a purity of no less than 95% (mass fraction) and of trace impurity in the concentration range of 0.0001%~1.000% (mass fraction).
