The test checks the 9 +humidity resistance of suit elements like the helmet, the PLSS (portable life support system), the 10 +communication system and other hardware. Potential hazards within the tests are condensation and 11 +fire. The Humidity test involves three Subtests (A-C). 7 7 13 + 14 +**Subtest A: **The tested temperature is set at 30° Celsius and at a RH (relative humidity) of 75%. This 15 +Subtest checks the temperature of the helmet and the PLSS. Also it checks the functionality of the 16 +communication system, the sensors and other hardware under these circumstances. The test will 17 +take about 8 minutes. 18 + 19 +**Subtest B: **The tested temperature is set at 30° Celsius and at a RH of 100%. The same fields are 20 +tested, but under a higher percentage of relative humidity (temperature of the helmet and PLSS, 21 +communication system, sensor functionality, other hardware). 22 + 23 +**Subtest C: **The tested temperature is set at __**//XX° (TBC)//**__ Celsius. In this test, the functionality of the 24 +same fields as in Subtest A and B are checked but under light rain conditions. To start the test the 25 +rain simulator has to be checked and the space suit has to be transported outside. The temperature 26 +of the helmet and the PLSS are checked before starting the rain simulation (two meters over the 27 +suit). Now the same checks are carried out (temperature of the helmet and PLSS, communication 28 +system, sensor functionality, other hardware). 29 + 30 + 31 +)))
