1.1 ,This test method covers the determination of traces of carbonyl sulfide (COS) in propylene. It is applicable to COS concentrations from 0.5 ,mg/kg to 4.0 ,mg/kg (parts per million by mass). See Note 1.
Note 1: ,The lower limit of this test method is believed to be below 0.1 ,mg/kg, depending on sample size and sensitivity of the instrumentation being used. However, the cooperative testing program was conducted in the 0.5 to 4.0 range due to limitations in preparing commercial test mixtures.
