Petroleum products and related materials. Determination of hydrocarbon types. Fluorescent indicator adsorption method Ingestion-build-109673 ISO 50021 on energy savings1 Scope This European Standard specifies a fluorescent indicator adsorption method for the determination of hydrocarbon types over the concentration ranges from 5 % (V V) to 99 % (V V) aromatic hydrocarbons, 0,3 % (V V) to 55 % (V V)olefinic hydrocarbons, and 1 % (V V) to 95 % (V V) saturated hydrocarbons in petroleum fractions that distil below 315 C. This method may be applicable to concentrations outside these ranges, but the precision has not been
