Mike:
Annex II of the End of Life Vehicles (ELV) directive (2000/53/EC) provided
the following limits for haz mats:

a maximum concentration value up to 0,1 % by weight and per homogeneous
material, for lead, hexavalent
chromium and mercury and up to 0,01 % by weight per homogeneous material for
cadmium shall be tolerated,
provided these substances are not intentionally introduced.

A copy of the annex can be found here:

I think the RoHS limits will likely be similar.  The real question mark is
the "intentionally added" requirement.  Very tricky and hard to enforce.

Cheers,

Bob

Subject: [LF] Lead percentages


In June of 2003 I attended a lead free seminar sponsored by AEA, at
Solectron in San Jose.  One of the clear statements made by the presenters
of the seminar was that "there are currently no thresholds or de minimis
exemptions set forth in the RoHS Directive.  The Directive contemplates,
however, the preparation of amendments by the EU addressing this issue".

Can anyone tell me if there have been any firmly established thresholds for
lead established by the EU?  I read that the EU has established < 0.1% as
the "lead free" standard, but am not aware of it being formally adopted.

Also, has there been any formal adoption of what level the lead content of
an electronic product is to be controlled at: raw material, component,
subassembly, assembly, finished good?  In other words if I use standard tin
lead solder, at a component level it will certainly fail the <0.1%
requirement but if lead percentages are based on the end product and the end
product is a fairly large assembly that has overall low lead content then I
may pass.  Have these levels been established?  I get conflicting reports
from vendors and customers and would like to put this to bed if the EU has
moved in a decision.

Thanks for any and all help.
