(b)reacts readily with water at ambient temperatures so that the maximum rate of evolution of flammable gas is equal to or greater than 20 litres per kilogramme of substance per hour; or | II | |||||
(c)reacts slowly with water at ambient temperatures so that the maximum rate of evolution of flammable gas is greater than 1 litre per kilogrammme of substance per hour. | III | |||||
Oxidising substance | A substance other than an organic peroxide which, although not necessarily combustible, may by yielding oxygen or by a similar process cause or contribute to the combustion of other material. | A solid substance which, when mixed with cellulose in a ratio of either 1:4 or 1:1 by mass, exhibits a burning rate at least as fast as that for a— | 5.1 | OXIDIZING AGENT | ||
(a)3:2 mixture by mass of potassium bromate and cellulose; | I | |||||
