что означает этот знак (маркировка на товаре)

In China, RoHS compliance is indicated through the Electronic Information Products (EIP) label including an Environment Friendly Use Period (EFUP) label. EFUP refers to the time after which a RoHS-containing product is likely face leaking out of these substances. EFUP-labeled products have a circle within which the duration (in years) before this leaking is indicates, so for example an encircled 8 indicates that the RoHS-substances in this product are likely to leak out after 8 years. EFUP labels with an encircled green “e” indicate that the RoHS substances in the related product are below the maximum concentration limits (<100ppm or 1000ppm respectively). - See more at: http://sinovoltaics.com/topics/rohs-certification/#sthash.OCclhjdU.dpuf
