PART IICAPACITY MEASURES

1.  (1)  The prescribed limits of error for capacity measures in relation to the passing of any such measure as fit for use for trade shall be the appropriate amount specified in paragraph 2 or 3, as the case may be, of this Part of this Schedule.

(2) The prescribed limits of error for capacity measures in relation to the obliteration of the stamp on any such measure shall be—

(a)in the case of a capacity measure other than an apothecaries measure—

(i)if the error found on testing is in deficiency, an amount equal to half the corresponding amount prescribed in relation to the passing of such measure as fit for use for trade;

(ii)if the error so found is in excess, an amount equal to the corresponding amount prescribed in relation to the passing of such measure as fit for use for trade;

(b)in the case of an apothecaries measure (and whether the error found on testing is in deficiency or excess), an amount equal to the corresponding amount prescribed in relation to the passing of such measure as fit for use for trade.
