Hello Grahm,
to be RoHS-2 (2011/65/EU) compliance it means six substances limited and not
only Lead.
By using XRF (hand-held or Lab version, both costly instruments )you could
detect in a reliable way only some of those 6 substances.
Also, analysis and test need to be performed according to Test Methods
indicated by IEC 62321 Standard, where they address you how to prepare
samples (by homogeneous part), suitable instruments, test methods, etc.
See the partial document available on this link, take a look...
http://www.cj-elec.com/UploadPicFile/2012116153542929.pdf
To declare (certificate) parts RoHS-2 compliant, it is mandatory to perform
test according to IEC 62321. Most of certificate of compliance for parts
available on the market, they v refer to IEC 62321.
Etc...
LeadCheck swabs, it work as quick way to identify if lead is on surface, but
it detects (red color) around > 2000 ppm of Lead (RoHS limit is 1000ppm), by
the way, if the swab gets red, it means that Lead is there.

Good day TechNet
We are a late arrival to the lead-free party, as our customers thus far
are exempt. But a couple of them see the writing on the wall and are
moving toward RoHS compliance. Which leads me to two questions with
regards to our testing of parts to ensure compliance.
The first question - what XRF? We are concerned with price given that
we are dipping our feet here, does anyone have a recommendation for a
good but inexpensive unit?
Second question is concerning alternative test methods, a customer is
planning to use 3M LeadCheck swabs (LC-8S10C) to ensure no lead. Given
that the product is described as for use on painted surfaces I don't
think this is intended as a way to verify lead-free status on
electronics. Any comments on this?
Thanks!
