    We have our ancient autoclave pressure tested each year (automatic unit, only option). 
    However, I've taken the steam engine out of use as we cannot afford to test it. I will buy a new pressure cooker annually (or as required when we have autoclave issues) as it is much cheaper than specialist testing. Being "green" or "encouraging engaging demonstrations" has been thrown out of the window, purchase for single/limited use and disposal is my only option as our finances are simply running on empty.

    Does anyone do their own pressure testing in line with CLEAPSS recommendations and have better experiences, or perhaps suggestions to improve mine?

    Every five years are DIXON model is tested. Other years I put a pintof water in the unit and time how long it takes to reach manufacturers recomended temperature and pressure. I just sign off on our shet that this has been done and we have no issues

    I used to have insurance company look at our pressure cooker annually and, when they decided it wasn't in their remit to test, I'd check it annually. However, with the change in law I can no longer do that. Who did you get to write/sign off your Written Scheme of Work? Did you have to do the pressure testing course to be able to sign off annually as a "competent person"? How much does it all cost? 

    (Just noted that the Dixon is a thermostatically controlled autoclave - do you test safety valves and over-temperature cut-outs as well as putting it through a cycle?)

    About five years ago, I got the entire Dixon Autoclave serviced. New element, pressure valve, PAT tested etc, to bring it up to spec. The bill for this was massive! I got a certificate of Inspection with the work that was done. In the calibration certificate/Inspection the company speified the standards they were using and the work that was done to bring the unit into compliance which included how long it takes to bring to temppressure a speifified volume of water.
    From this information I developed my own SOW which includes as part of the units annual inspection that which is recomended by CLEAPPS and a self check list that I have done this, after each use - plus formal the end of the year. check.
    CLEaPSS recomend that the unit has to go through formal inspection every five years. None of the competent plumbers that we employ have a clue about  how to inspect, calibrate the autocalve. It would have to be sent back to the manufacturer. Once again, very costly..
    However, by following my own SOW in line with what the manufacturer and CLEAPSS recomendations that should satisfy any saftey regime.

    Thanks for the reply.
    You are obviously happy with your method, which is fine.
    However I would recommend any others reading this thread and thinking of taking a similar route as a "cheap way out" to look into the Pressure Testing Regulations (via CLEAPSS if you're a member) very carefully and ensure your H&S officer is satisfied that your level of competence and the testing/auditing methodology chosen conforms to the requirements of the regulations. If it does, and it saves some money, that's a job well done.
