Chen Yong;Lv Feng;Wang Xuewu;Hu Chengqun;Jinhua Inspection Institute of Quality and Technical Supervision;
The lead content in automotive coatings was determined by microwave digestion and Inductively Coupled Plasma-Optical Emission Spectrometry(ICP-OES). By creating a mathematical model and selecting the evaluation method,the uncertainty of various factors affecting the test results was evaluated. Finally,the expanded uncertainty of lead content was calculated,it would make determining results more objective and accurate.
