Tom, Be warned, something like this was tried by a UK manufacturer. They failed the tests, then persauded a Competent body to sign off a TCF stating that the failed tests were not applicable or were unpassable by their equipment. They then CE marked and placed on the market. Within their documentation they placed a warning about how it should be used which effectively negated the CE mark. The local Trading Standards body (the UK CE policeing body) found out. They did not take them to court, but made them withdraw all their products(several thousand) and fix the problem so the equipment passed.
And their equipment did pass after redesign.

I feel that too often TCFs are written just to get around test failures or to bypass testing even when standards apply. Some test houses are even implying in their advertising that they can "get around the testing" by writing a TCF.
