What this standard covers

This standard specifies two methods for the determination of residual blowing agents in rigid polyurethane foams by headspace gas chromatography, Method A hydrogen flame ionization detector (FID) and method B electron capture detector (ECD). This standard applies to rigid polyurethane foam density range 30kg/m ^ 3 ~ 80kg/m ^ 3. Method A is suitable for the determination of alkanes (cyclopentane, isopentane) and methyl formate blowing agent in rigid polyurethane foam; Method B is suitable for the determination of chlorofluorocarbons (CFC-11), hydrogen Determination of blowing agents for hydrochlorofluorocarbons (HCFC-141b, HCFC-22) and hydrofluorocarbons (HFC-245fa, HFC-365mfc, HFC-227ea, HFC-134a) this
