(2) Subject to sub paragraphs (3) and (4) it shall be determined, by way of a germination test, whether the seed attains the percentage of germination for the relevant level specified in columns 2 and 3 of the table set out in sub paragraph (1) for the appropriate category of seed.
(3) Sub paragraph (2) shall not apply to seed that has been subjected to a tetrazolium test carried out by the Scottish Ministers or a licensed seed testing station to establish the viability of the seed unless the result of the test casts doubt on whether it will satisfy the applicable germination standard set out in column 2 of the table set out in sub paragraph (1).
