United Kingdom

1. (i)The information provided, must describe the physical and chemical properties of active substances and together with relevant information, must serve to characterise them. In particular, the information provided must permit:
2. (ii)Division (ii)
3. (iii)Division (iii)
4. (iv)In certain specified instances, tests must be conducted using purified active substance of stated specification. In such cases the principles of the method(s) of purification must be reported. The purity of such test material, which must be as high as can be achieved using the best available technology, must be reported. A reasoned justification must be provided in cases where the degree of purity achieved is less than 980 g/kg.
