Yes I've seen it many times. One example was a test report for screw that showed a small amount of
Cr6. After questioning the supplier, they in fact used a Cr6 coating. You have to be careful and
scrutinize each report.

Re: [LF] Declaration of compliance with material

Hello all
I used to have dark brown hair but now I am gray!
Am I the only one or are others experiencing companys that provide a
declaration of compliance for their product and also send a material
analysis of the sub-components which is not performed to the Homogeneous
level just the whole sub-component ground up and tested?
Management here is asking if we are misinterpreting the Homogeneous level
compliance requirement for a product incorporated into our product. Seems
that some products (OEM and non-OEM) purchased are tested this way. When
reviewing the sub-component analysis, for example lead may be 129 ppm.
Figuring 10% (high)of the total weight of a connector is plating where the
lead would be found, then one could assume that at the homogeneous level
(plating) lead would be 1290 ppm which is over the limit.
Comments?
Thanks,
Denis

Hi Again David, BrianE, Genny, IPC LF Listservers,
David, Lots of good notes and thinking were posted that will hopefully help
you with your customer and will help us think through the many situations.
Following BrianE's logic which is good, and that crazy, to me, teddy bear
example in the Guidance documents, I thought about Large Household
Appliances and other similar future complications.
Now most of us know that the EU hopes to recover, reuse large household
appliances to reduce them going in the dump. (80% goal). YET if I have a
Gas fired range/stove, clothes washer, clothes dryer, or other major
appliance are the electrical/electronics that part of these appliances
enough to make them EEE or is the electronics/electrical portion of these
appliances just a tag along to their prime function. I.E. the teddy bear
example used for other products. The full gas stove, with minimial
electronics except for sensing/control is probably a weaker EEE than a
talking, winking, human interacting, solar powered teddy bear.
Yours in Engineering, Dave
YiEngr, MA/NY DDave
