b) the solution contains at least 7 per cent water;

c) the solution contains not more than 0.2 per cent combustible material;

d) the solution contains no chlorine compounds in quantities such that the chloride ion level exceeds 0.02 per cent;

e) the pH of an aqueous solution of 10 per cent of the substance is between 5 and 7, measured at 25ºC; and

f) the maximum allowable transport temperature of the solution is 140ºC.

Ammonium nitrate hot concentrate solutions are not subject to these Instructions when carried as cargo, provided:

a) the solution contains not more than 80 per cent ammonium nitrate;

b) the solution contains not more than 0.2 per cent combustible material;

c) the ammonium nitrate remains in solution under all conditions of transport; and
