(3) The tertiary standards shall consist of such standards of such of the measures or weights set out in Parts I, IV and V of Schedule 3 to this Act as may from time to time appear to the Secretary of State to be necessary or expedient; and any such standard shall be constructed and, while it remains in use, from time to time at intervals not exceeding two years have its value or values redetermined, by reference to such one or more of the secondary standards as may appear to the Secretary of State to be appropriate.

(4) The coinage standards shall consist of such standards of the weight of each coin of the realm for the time being authorised by or under the enactments relating to the coinage as may from time to time appear to the Secretary of State to be necessary or expedient; and any such standard shall be constructed and, while it remains in use, from time to time at intervals not exceeding two years have its value redetermined, by reference to such one or more of the secondary standards as may appear to the Secretary of State to be appropriate.

(5) Department of Trade and Industry standards shall be provided or replaced by the Secretary of State from time to time as may appear to him necessary or expedient and shall be in such form and of such material, and be kept under his control at such place or places, as he may think fit.
