RTCA/DO-160 Section 10 analyzes how aircraft responds to water under normal conditions and consists of the following tests:
- Condensing Water Drip Proof Test (Category Y)
- Drip Proof Test (Category W)
- Spray Proof Test (Category R)
- Continuous Stream Proof Test (Category S)
Of the four tests, ATEC rents chambers to complete testing for Category Y. This condensing water test requires the use of two
temperature and humidity chambers; chamber 1 set to -10° C and chamber 2 set to 40° with 85% relative humidity. The equipment under test is placed (non-operating) into chamber 1 for three hours, then transferred to chamber 2 and operated for 10 minutes. Upon completion, the equipment is evaluated to determine compliance.
Equipment Categories
Category Y
Equipment that is installed in locations where it is subjected to condensing water in the course of normal aircraft operations.
Category W
Equipment that is installed in locations where it is subjected to falling water (generally the result of condensation) in the course of normal aircraft operations.
Category R
Equipment installed in locations where it may be subjected to a driving rain or where water may be sprayed on it from any angle.
Category S
Equipment installed in locations where it may be subjected to the forces of a heavy stream of fluid such as would be encountered in aircraft de-icing, washing or cleaning operations.
