Recommended Practice for Splash and Spray Evaluation
- Ground Vehicle Standard
- J2245_200209
- Reaffirmed
Scope
-
a
It only applies to “A-B” comparisons done under the “same” conditions as outlined in the test procedure.
-
b
Tests done at different sites may not necessarily be comparable, depending on the exact conditions and specific site locations at the time of the tests.
-
c
Because uncontrollable variables such as wind speed and direction, water depth, humidity, and temperature can have a profound effect on measured results, small differences (on the order of 10 to 15%) in measured splash and spray may not be meaningful and the relevance of such small measured differences should be viewed with caution.
-
d
Results from the testing should be reported as the difference between the 95% confidence bands and not as the differences between averages.
-
e
Each configuration tested shall have a separate value with 95% confidence bands reported for each of eight wind conditions using the downwind rule, as outlined in the data reduction.
