In 2002, NEMA negotiated a settlement with Mateel on behalf of a group of
wire and cable manufacturers. The settlement covers 20 different
substances on the Prop 65 list, including several lead compounds. If the
outer layer of a frequently handled cord contains more than 300 ppm of
lead, then it must have a Prop 65 warning label. Labelling is not required
for any materials that are not on an outer surface where they would likely
be handled, or on infrequently handled wire and cable (e.g., refrigerator
power cord or internal equipment wires). NEMA put out a fact sheet that is
available on Belden's web site:
http://bwcecom.belden.com/Sales/Quality/Prop65QA_NEMA.pdf
The lead is used as a heat stabilizer in PVC and elastomeric compounds (as
in the jacketing on wire and cable), but lead-free alternatives (e.g.,
Ca-Zn) are available for all applications, and are being increasingly used
by manufacturers. We have been working with this industry for several
years in Massachusetts to make sure that they will be ready to comply with
the EU RoHS.
