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.
