Compliance and Verification of Standards and Labeling Programs in China: Lessons Learned

摘要

After implementing several energy efficiency standards and labels (30 productsrncovered by MEPS, 50 products covered by voluntary labels and 19 products by mandatoryrnlabels), the China National Institute of Standardization (CNIS) is now implementingrnverification and compliance mechanism to ensure that the energy information of labeledrnproducts comply with the requirements of their labels. CNIS is doing so by organizing checkrntesting on a random basis for room air-conditioners, refrigerators, motors, heaters, computerrndisplays, ovens, and self -ballasted lamps. The purpose of the check testing is to understandrnthe implementation of the Chinese labeling scheme and help local authorities establishingrneffective compliance mechanisms. In addition, to ensure robustness and consistency ofrntesting results, CNIS has coordinated a round robin testing for room air conditioners. Eightrnlaboratories (Chinese (6), Australian (1) and Japanese (1)) have been involved in the roundrnrobin testing and tests were performed on four sets of samples selected from manufacturer’srnproduction line.rnThis paper describes the methodology used in undertaking both check and round robinrntesting, provides analysis of testing results and reports on the findings. The analysis of bothrncheck and round robin testing demonstrated the benefits of a regularized verification andrnmonitoring system for both laboratories and products such as (ⅰ) identifying the possiblerndeviations between laboratories to correct them, (ⅱ) improving the quality of testing facilities,rn(ⅲ) ensuring the accuracy and reliability of energy label information in order to strength thernsocial credibility of the labeling program and the enforcement mechanism in place.
