4 Environmental legislation impacting the manufacturing industry Global status EU : WEEE & RoHS China: Planning legislation - Regulation for Pollution Control of Electronics Products (RPCEP), likely to come into force before July 01, 2006. Japan: No lead ban at present but many Japanese manufacturers already changing to lead-free technology as a result of recycling laws. Lead solder ban is planned. USA : Plans for legislation in California and other States. 15 states have active, or pending, WEEE-like product take-back laws. 5 states dictate that manufacturers provide advance notice of mercury content and a further 5 states insist on a special label. Rest of world: likely to follow.

RoHS : EU Member States shall ensure that, from 1 July 2006 , new electrical and electronic equipment put on the market does not contain : [ RoHS Compliance means within RoHS Limits ] 1. Lead ( Pb ) <0.10% component weight = <1000 PPM 2. Mercury (Hg) <0.10% of component weight = <1,000PPM 3. Cadmium (Cd) <0.01% of component weight = < 100 PPM 4.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
