Using liquid nitrogen to make a slush bath out of R-12 refrigerant fluid "Freon-12" -- difluoro-dichloromethane will give a stable temperature of -157 degreec C. From the time the nitrogen boils off, until all the frozen R-12 melts, the temperature will hold at -157. Another option is to find a testing lab with an ultrafreezer to perform the inpact testing [Charpy?] for you. Your specimens are small and light. Airmailing them to a lab is fairly inexpensive.                  Reply  Translate  Close   anjafo79 NDT Inspector Norway, Joined Aug 2009, 204 anjafo79 NDT Inspector Norway, Joined Aug 2009 204 22:48 Oct-23-2009 Re: Impat Testing @ -150 Deg C In Reply to Slimmoon at 19:44 Oct-22-2009 (Opening). cant you just use original solution and let it warm up a little ;)                  Reply  Translate  Close   Product Spotlight NozzleScan: Radial nozzle scanner with probe skew StandPhoenix Inspection Systems Limited NozzleScan is a versatile manual scanning solution developed for the inspection of nozzle welds in ... both set-through and set-on configurations.
