the standards committees are not yet willing to jump into requirements
that they don't yet understand and aren't yet ready to deal with.
It's not rocket science; I suspect designers are somewhat vague because
the touch current paths in the product are somewhat elusive:
- capacitance between live parts and grounded metalwork; is it 10 pF or
10 nF?;
- ground current through EMI filter capacitors; they live in a tin box
that is a bought-in part, so presumably the supplier solved any
touch-current issues?
The problem will get worse before it gets better.
Probably.
