- Scope
- This standard specifies the principles, reagents or materials, instruments and equipment, samples, test procedures, test data processing and test reports for determining the fluorine content in powder coatings. This method is suitable for the determination of fluorine content in solvent-soluble matter in powder coatings. For powder coatings containing polyvinylidene fluoride (PVDF) or fluoroolefin/vinyl ether (ester) copolymer resin (FEVE), the oxygen bomb combustion-ion selective electrode method is used to determine the fluorine element content in the solvent soluble matter; for For powder coatings containing polyvinylidene fluoride (PVDF), the centrifugal separation method is used to determine the content of PVDF resin in solvent soluble matter. The determination of organic fluorine content in related materials can also refer to this standard.
