So I was reading the DOT and Military specs for O2 cleaning and testing of AA and AL cylinders, and came across this bit of RR-C-901D, section 4.3.2.1 at http://assist.daps.dla.mil/docimages/0004/03/71/901D.PD5 regarding testing for Oils and hydrocarbons in cylinders after an O2 cleaning. It specifically refers to the Evaporation Method by "[evaporating] the extract to dryness at slightly below the boiling point and finish[ing] the drying in an oven at 221 ºF (105 ºC) ± 1.8 ºF (1ºC) for 15 minutes. Cool, weigh, and report as milligrams of extracted oil."
What I'm specifically curious about is whether anyone's used the baking in an oven at 221 F for 15 mins to merely dry the cylinder after running solvent (eg. Simple Green solution) through. I'm having a hard time rigging a blow dryer to effectively dry the inside and thought this might be easier ;P
