摘　　要：本研究通过检测皮革制品中Cr_(2)O_(3)和甲醛的含量并分析测试结果,探讨了基于评估结果的化学测试分散度的评估方法。分别采用滴定法测定Cr_(2)O_(3)的含量、水萃取法测定甲醛的含量,建立相应的不确定度评估数据模型,分析不确定度的主要来源,并合成各分量。当置信概率为95%,Cr_(2)O_(3)含量为30.2%,扩展不确定度为1.3%;如果甲醛含量为102.6 mg/kg,其扩展不确定度为1.5 mg/kg。This study explores the evaluation method of chemical testing dispersion based on the evaluation results by detecting the content of chromium oxide and formaldehyde in leather products and analyzing the test results.The titration method was used to determine the content of chromium oxide,and the water extraction method was used to determine the content of formaldehyde.A corresponding data model for uncertainty evaluation was established,and the main sources of uncertainty were analyzed and each component was synthesized.When the chromium oxide content is 30.2%,its expanded uncertainty is 1.3%;When the formaldehyde content is 102.6 mg/kg,its expanded uncertainty is 1.5mg/kg;The confidence probability of uncertainty for chromium oxide and formaldehyde is 95%.
