Hi Brent,
Even HDMI test sources like Quantum Data or Agilent machines are noisy and/or
have average signal quality.
Your cables will be a significant factor, expensive =/= well shielded. But it
sounds like you know this already.
Shopping around and doing lots of testing would probably be your
You could try building one?

Our internal people working on and maintaining RoHS compliance are having a
very difficult time getting the cooperation we need from our Hardware suppliers
(nuts, bolts, washers, etc.). Our company manufacturers a relatively small
quantity of products so it is impossible for us to purchase

I have heard of mfgs using XRF guns to inspect their incoming stock. However
this is generally not accepted as a initial qualification, only to validate
incoming material as an A / B comparison. RoHS still requires a ppm assessment
after breaking down to homogeneous levels.

Could you purchase parts from the UK or Europe? RoHS is pretty much the 'norm'
in Europe and the small volume distribution companies like RS, Farnell and
many, many others now sell only (well, mostly) RoHS compliant product, while
declaring the RoHS status of products in their catalogues/web
Teradata Labs in San Diego has an immediate opening for a test technician or
engineer to serve in a role in EMC testing in a lab performing compliance
testing for FCC, CISPR 22 and 24. A minimum of three years of experience is
preferred, but not a requirement.

There is a harmonized standard (EN 50581:2012 )now to accompany the RoHS
Directive. Complying with the standard provides you with the legal presumption
of compliance with the RoHS Directive. The standard requires you to (a)
collect information on the RoHS compliance of your nuts,
Based on a year of spot XRF testing hardware procured from a supplier with a
pretty good RoHS program in place:
1. Zinc with clear chromate is low risk.
2. Yellow chromate traditionally is hexavalent chromium and therefore verboten
under RoHS.
3. Black chromate may or may not be RoHS
Jim,
This is exactly the motivation behind my original email.
How can the trustworthiness of a supplier be evaluated without testing? In a
long supply chain it only takes one buyer to mess up the batch. And the larger
distributor companies buy from the largest number of suppliers making the
Brian,
May I be candid here. A local hardware store in the USA is not going to have
traceability to RoHS compliance. It is highly likely they won’t even know what
it is. Testing is way too expensive and time consuming, I would even go as far
to say it’s unreliable as well. Procurement from a
Brian,
The standard does not require a guarantee that the supplier’s products comply
with the Directive. It asks for a good faith, due diligence effort in
assessing the trustworthiness of the supplier’s information through procedures
you put in place to evaluate the trustworthiness. These
