Regulation 27 Unsuitable use of instrument used for trade
If it appears to an authorised person that an instrument is used for trade—
(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 authorised person may affix a disqualification sticker to the instrument; and any such sticker shall be affixed in such a position that it is clearly visible when the instrument is in its regular operating position.
