Doug, I am not an official UL person but based on my experience of working on this standard , i saw some information for this test requirement.
Yes, there is a provision for Hydrostatic test at recent version of UL61800-5-1 under 5.2.7 (Type test and production routine test). Requirement for type test is 2 times the operating value or 1.5 times the maximum pressure rating of the device whichever is the greater pressure for 1 minute. For routine or production test , pressure needs to increase at its operating value for 1 minute. There is 4.4.5.2.4 Leakage of coolant section and 4.4.5.2.4DV (also 4.5.2.2) talks about pressure relief mechanism and cooling system requirement to satisfy the test requirement. By the way, Feb.1st of 2016 was the last day to evaluate new products under 508C (correct me if i am wrong). Can we open the file and update ratings that required test using 508C if needed after this Feb.1st deadline ? Hope it helps! Thank you.

"Just my opinion/ statement PSES, it isn't from my company's official statement" From: Doug Powell <[email protected]> To: [email protected], Date: 02/01/2016 05:37 PM Subject: Re: [PSES] UL 508C transition to UL 61800-5-1 All, In reviewing the details it is possible the UL committee followed the IEC standard a little closer than I had thought. The table of contents at http://ulstandards.ul.com/standard/?id=61800-5-1_1 has no indicaiton of such a test but the IEC versoin of teh standard has clause 5.2.7 for hydrostatic test. the UL standard seems to skip over this. It seems a bit crazy the committee would toss out whole sections and then call the standard harmonized. Thanks, Doug On Mon, Feb 1, 2016 at 4:18 PM, Doug Powell <[email protected]> wrote: All, I am presently working with a 10 MW inverter that uses water cooling. In the past, the UL inspector has said we should use sections from UL 508C - 67.1 Loss of cooling medium circulation test & 67.2 Hydrostatic pressure test. The new UL 61800-5-1 has no such provisions. I did a little research and my first thought was to look into UL 1012 which is also used for some types of industrial power conversion equipment, but it was of no help. I looked into UL 61010-1 and the fluid containing parts section seems possible but using a laboratory equipment standard for a 10 MW inverter seems a bit out of line. The original tests in 508C could be used but it is being withdrawn from use this month. Has anyone faced this problem and found an acceptable solution? thanks, Doug -- Douglas E Powell [email protected] http://www.linkedin.com/in/dougp01 ᐧ -- Douglas E Powell [email protected] http://www.linkedin.com/in/dougp01 - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
