4. Every capacity serving measure shall be sufficiently strong, rigid and stable to withstand the wear and tear of ordinary use in trade.
5. Every capacity serving measure shall —
(a)neither affect, nor be affected by, the intoxicating liquor which it is to be used to measure; and
(b)if of plastic, after immersion in water at 95°C for 10 minutes, resist deformation under hand pressure and not shrink, distort, split or show signs of striation.
6. Every capacity serving measure shall be constructed so that no air is trapped on filling and no liquid retained on emptying when tilted to an angle of 135° from the vertical.
7.—(1) Capacity serving measures may be either —
(a)brim measures, which shall have a plane rim and be of a nominal capacity in column 1 of Table 1 in the Schedule to these Regulations; or
(b)line measures, which shall be of a nominal capacity in column 1 of Table 2 in the Schedule to these Regulations and marked with a line which shall be —
(i)on the inside or outside surface of the measure;
(ii)conspicuous and durable;
(iii)of a thickness of not less than 0.5 mm and not more than 1.5 mm;
(iv)subject to paragraph (2) below, of a minimum length as set out in column 5 of the said Table 2 for a measure of the relevant capacity; and
(v)at a minimum vertical distance from the top of the line to the plane of the brim as set out in column 3 of the said Table 2 for that measure, and at a maximum vertical distance from the top of the line to the plane of the brim of four times the relevant minimum distance.
(2) Where the minimum length of line referred to in paragraph 1(b)(iv) above is 25 mm, a line measure may instead be marked with two equal co-linear lines which, together with a separation of 2 mm, total not less than 25 mm.
8. A capacity serving measure shall not rock, and its brim and lines shall be reasonably horizontal, when it is on a flat horizontal surface.
9. Every capacity serving measure shall remain reasonably perpendicular when rotated about its vertical axis.
10.—(1) Every capacity serving measure shall have its nominal capacity conspicuously, legibly and durably marked on the outside of the body of the measure (and not on any handle, bottom, rim, edge or stem) in the case of imperial measures in fluid ounces or pints and in the case of metric measures in millilitres or litres, in full or by means of one of the following abbreviations or symbols only —
fl oz, pt, ml, L or l
(2) The nominal capacity shall be marked —
(a)in the case of a brim measure, adjacent to the brim, in characters of a minimum height as set out in column 3 of Table 1 in the Schedule to these Regulations;
(b)in the case of a line measure, at the line denoting the nominal capacity, in characters of a minimum height as set out in column 4 of Table 2 in the said Schedule.
(3) Capacity serving measures —
(a)over 10 fl oz in the case of imperial measures may be subdivided into multiples of ½ pt only;
(b)over 250 ml in the case of metric measures may be subdivided into multiples of 250 ml only; and
(c)of a nominal capacity of 1 litre may be subdivided at 700 ml and at no other point;
and such subdivisions shall be —
(i)lawful for use for trade; and
(ii)marked on the measure in the same field of view as the nominal capacity.
(4) The number of subdivisions shall be marked on the measure, and each subdivision shall be marked with the capacity it defines.
(5) The marking of the nominal capacity, an indication of the type of measure (brim or line) and the number of subdivisions may be incorporated with the stamp, provided that, in the opinion of the inspector, such marking of additional information is permanent, legible and conspicuous and is not likely to cause confusion in use.
