CAN3-Z223.25-M86 (R1999):1986 Edition

This Standard applies to the measurement of vinyl chloride in air, using grab samples or integrated samples, usually collected by continuous adsorption in a sorbent tube over a period of time. This Standard employs gas chromatography for the measurement of concentrations of vinyl chloride in air between 0.01 mg-m-3 and 2600 mg.m-3 at 25° C and 101.3 kPa. Grab samples may be employed for vinyl chloride concentrationsdown to about0.5 mg.m-3; for lower concentrations an integrated sample is required. Note: All concentrations referred to throughout this Standard are based on standard conditions of a temperature of 25°C and an atmospheric pressure of 1 01.3 kPa. unless otherwise stated.
