PART D INTERPRETATION

In this Schedule—

(a) references to percentages are references to parts by weight of the substance per 100 parts by weight of the solution;

(b) “compound fertiliser” means a fertiliser containing ammonium nitrate and phosphate or potash;

(c) Part C does not include a substance which is within Part A or Part B;

(d) a substance, or any mixture of substances, shall only be treated as a hazardous substance by virtue of satisfying a description in entry number 37, 66, 67, 68, 69 or 70 when it is in a state in which it satisfies the description;

(e) the controlled quantity of 25 tonnes in entry 69 refers, in the case of a mixture of substances, to the quantity of substances within that mixture held above their boiling point (measured at 1 bar absolute);

(f) the controlled quantity of 50 tonnes in entry 70 refers, in the case of a mixture of substances, to the quantity of substances within that mixture having boiling points below 0°C.
