Spray Characteristics 13: Drop Size Distribution: Practical Considerations: Drop size data depend on many variables, and are always subject to interpretation. The following guidelines are suggested to facilitate understanding and effective use of the drop size data. Data collection repeatability and accuracy: A drop size test is repeatable if the data from individual tests do not deviate by more than ±10%. If a test result indicates a VMD of 100 µm, another test with results ranging from 90 to 110 µm can be considered identical. Instrumentation and reporting bias: To make valid data comparisons, particularly from different sources, it is extremely important to know the type of instrument and range used, the sampling technique, and the percent volume for each size class
