This procedure shall be documented.The mass of the prepared test piece shall be determined and documented.The feed rat
36、e of the spray material shall be determined in g/min in at least two runthroughs in order to calculate the mean value.The test pieces shall be coated applying the spray parameters selected. The spraying angle shall be within (90 10). If risk of overheating exists, suitable cooling steps shall be tak
