Abstract： According with EU Directive 2002/95/EC Restriction of Hazardous Substances (RoHS Directive) and same national regulation of China, National Institute of Metrology（NIM） has a program for correlative national chemical metrology traceability system establishment in this field. Three important parts were included in this werk：primary measurement method researches and some certified reference material developments； international cooperation and comparisons for MRA；national proficiency tests, standards resource and knowledge sharing. With the successful achievements of this work, the measurement results in the international trade get comparable and the measurement levels of whole testing laboratories in China would be improved. 

Key words： RoHS directive; Chemical metrology; Traceability; Reference material; International comparison
