英文摘要:

      This paper is the translation of the European standard EN 13804:2013: Foodstuffs - Determination of elements and their chemical species - General considerations and specific requirements. This standard specified the general considerations and special requirements for the determination of elements and their chemical species in food, including a process from receiving samples by the laboratory to the final test result. It mainly included the considerations and specific requirements such as reagents, apparatus, equipment and storage requirements in the sample preparation and such as reagent, standard substance, containers and equipment in the analysis of trace elements in food, included the calculation method of the detection limit, quantitative limit, recovery rate and the measurement uncertainty, etc., included the quality assurance methods such as proficiency testing schemes(PT), using standard material (RM) or certified standard material (CRM). It also included the expression of the test result and the essential content in a test report.
