Stationary source emissions. Sampling and determination of gaseous fluoride content Ingestion-build-107062 What are BS EN 1402031 Scope This International Standard is applicable to the measurement of the gaseous fluorides that are entrained in gases carried in stacks or ducts. The gaseous fluoride content is expressed as a mass of hydrogen fluoride in the stack gas. This International Standard is applicable to all stacks emitting gases with fluoride concentrations of below 200 mg m3. It can be used for higher concentrations, but then the absorption efficiency of the bubblers
