RoHS, The Restriction of Hazardous Substances in Electrical and
Electronic Equipment Directive (2002/95/EC) is a European Union legal
requirement affecting the global electronics industry. RoHS requirements
must be implemented on Lenovo products placed on the market after June
2006. Products on the market before June 2006 are not required to have
RoHS compliant parts. If the original FRU parts are non-compliant,
replacement parts can also be non-compliant. In all cases if the original
FRU parts are RoHS compliant, the replacement part must also be RoHS
compliant.
