(a)A second seed shall not be regarded as an impurity if a second sample of the same weight is free from any seeds of other cereals species.
(b)The presence of one seed of Avena fatua, Avena sterilis or Lolium temulentum in a sample of the prescribed weight shall not be regarded as an impurity where a second sample of the same weight is free from any seeds of these species.
(c) In the case of varieties of Hordeum vulgare which are officially classified as of the “naked barley” type and in the case of varieties of Avena nuda which are officially classified as of the “naked oat” type, the minimum germination standard is 75%. In such cases the official label shall be endorsed ‘minimum germination capacity 75%’.
(d)In HVS Basic Seed the nil standard shall apply in respect of Agrostemma githago and Raphanus raphanistrum.
(e)For hybrids of rye. The presence of five ergots or fragments of ergot in a sample of seed of a hybrid of rye of the prescribed weight shall be deemed to be in conformity with required sample purity standards, where a second sample of the same weight contains not more than four ergots or fragments of ergot.
(f)In minimum standard seed, the standards shall apply in respect of Agrostemma githago and Raphanus raphanistrum only.

(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).
(4) Where a tetrazolium test is carried out on seed which does not comply with the Scottish Ministers' requirements for eligibility for tetrazolium testing or where the results of a tetrazolium test do not meet the standards set out in the Scottish Ministers' requirements in respect of such tests, the test will cast doubt on whether the seed will satisfy the applicable germination standards set out in column 2 or 3 of the table set out in sub-paragraph (1).
