70.—(1) This regulation applies to a regulated non-automatic weighing instrument.
(2) If it appears to an inspector that a regulated non-automatic weighing instrument used for a purpose mentioned in regulation 3(2)—
(a)for a purpose for which it is unsuitable; or
(b)in circumstances where it is subject to any extraordinary environmental or operating conditions which—
(i)may prevent it operating consistently or accurately; or
(ii)are likely prematurely to degrade its metrological characteristics,
the inspector may affix a disqualification mark to the instrument; and any such mark must be affixed in such a position that it is clearly visible when the instrument is in its regular operating position.
