检测方法可以参考IEC62321：2008电子电气产品中六种限用物质浓度的测定程序 　　

Detection method can refer to IEC62321: 2008 electrical and electronic products in six regulated substances concentration determination procedure

A.首先用XRF进行无损筛选，快速高效，非破坏性，成本低。但干扰因素多，误差较大。 　　

A first XRF non-destructive screening, fast efficient, non destructive, low cost. But many interference factors, error. 

B.微波消解、酸消解后利用AAS或ICP-AES测定Pb, Cd, Hg浓度。 　　

B. Microwave acid digestion, after using AAS or ICP-AES determination of Pb, Cd, Hg concentration. 

C. 索氏提取后用GC-MS测定多溴联苯、多溴联苯醚等的浓度。 　　

C Soxhlet extraction with GC-MS determination of polybrominated biphenyl polybrominated diphenyl ethers, the concentration of such. 

D. 利用点测试法或沸水萃取法测定无色表层Cr6+的浓度，或是用紫外可见光分光光度计按EPA3060A测试.。

D. The test method or boiling water extraction method for the determination of colorless surface layer of Cr6 + concentration, or by ultraviolet visible spectrophotometer by EPA3060A test..
