"Except where installed in a conduit or duct which provides equivalent protection against mechanical damage, a cable buried in the ground shall incorporate an earthed armour or metal sheath or both, suitable for use as a protective conductor."
FP200 does not have armour or a metal sheath, and plastic ducting does not provide equivalent protection against mechanical damage.
What you have there doesn't comply. Nor did it under the 16th - 522-06-03 said the same thing, plus insulated concentric.
