For the above test we used 1L of %90. We were actually going to use %85 but at the time we couldn't figure out how much water to add (its harder than it seems). Here is a excel spreadsheet my friend Robert Walker wrote to do it, I thought someone might find it usefull.
I was quite happy with how the test went and how everyone performed running the test but there definitely room for improvement on the logistics side. Firstly it was raining pretty heavily, and although everything was under a tent the water did make the test more difficult the it would have been otherwise, so no more testing in the rain. The tent should be for protecting everything if it rains, not for testing in the rain. It made the suit fog up and we couldn't really hear Buren read out the fill steps so he mostly went alone. Following on from that we need a better method of communicating with the person filling. I will getting a radio with a VOX headset. The filler should also wear a sweatband or something on his head so he can wipe any moisture on the inside of the suit.
We actually planned on doing two tests but when filling for the second test Buren found the tank only sucked a small amount of peroxide before it wouldn't take anymore which gave us all quite a fright as it could have meant that there was decomposing peroxide in the tank. We used the small amount of peroxide and vented and I decided not do try again but instead to disassemble and check everything. As it turned out the reason the system wouldn't take any more peroxide was because it had sucked a bunch of air initially (the tube wasn't properly in the peroxide container) but I thought it was better to be safe. Also we hadn't changed anything since the first test and the went fine so I don't think any contaminants could have gotten into the system. To deal with this I will install a pressure gauge on the system so in the unfortunate event there is peroxide decomposing in the system we know as it is happening.
We also need to stop doing nigh tests as it doesn't make things any easier.
