The UK believe that 6.10 does not contain the information necessary to determine the mass of coating material delivered by the atomizer for method 1 g

8、ravimetrically. The UK also drew attention to the fact that the measurement accuracy tolerance given in Annex A for the weighing of the coating material deposit is, in their view, too large. Finally, the UK consider that the contents of Annex C do not allow for the correct recording of test results.
