Peter,
REACH is based on the weight of the article, not the "homogeneous material
that is mechanically separable as it is for RoHS.

So, if you are talking about a PCB that is not populated, there is NO WAY
that there could be enough cobalt to fail REACH.

In an assembly I again can't believe there would be enough cobalt in the
ICs, hard gold, Superinvar and/or recording media to trigger the REACH
limit. Any chance they were stupid enough to grind up a Li ion (LiCo2)
battery is there?

Subject: [TN] Too much Cobalt in my PCB?

We just got a lab report back saying we fail REACH because of an excess of
cobalt.  The lab is trying to tell us it's the cobalt in the copper on the
PCB and ICs.

I tend to believe something else was ground up with the board, accidentally
or purposefully.  They did include the piezo sounder hanging off the board.
