NOTE For the purposes of this European Standard, the term “% (m/m)“
21、 is used to represent the mass fraction of a material. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (includ

EN ISO 3170, Petroleum liquids Manual sampling (ISO 3170:2004) 3 Principle The sample under analysis is exposed in a sample cell to the primary radiation of an X-ray tube. The count rates of the S-K X-ray fluorescence and the count rate of the background radiation are me
