Kind of makes you wonder if these cables are faulty or just incorrectly
classified by the distributors.Also a bit of a worry if a lot has already
been used before anyone found a problem. In practice I'd suggest it will
never come to light, but who knows, you can hardly recall cable once its
been fitted, who keeps records of which make of cable they put in to a
given installation.

But not hard to check what was used after a recall.

If that is the case then there are two approaches for
identification of problem cables (having identified it first by
makers stamp and date code). One would be if the diameter is
measurably different - probably only useful at non stranded CSAs.

The O.D. does not really matter; for stranded cables, just measure
the O.D. of a strand (with a sufficiently good micrometer or
otherwise) and multiply by the square root of the strand count.

Indeed you could, but the measurement accuracy required gets harder to
achieve.
