<div dir="auto">Im interested to see the results of this testing however, epoxies do have issues with aging, degradation of its overall thermo-mechanical properties will occur affecting its durability, reliability and safety. It would be interesting to compare any results with a sample that has been aged.<div dir="auto"><br></div><div dir="auto">Mike</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, 14 Nov 2022, 1:45 am hank pronk via Personal_Submersibles, <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi submarine friends. I just completed a pressure test to failure on our Cast Epoxy port. The port was 1 inch by 8 inches OD. An acrylic port this size is rated to fail at 2,100 feet sea water. My Epoxy port failed at 1,225 psi or 2,744 feet fresh water. <br>
Any ideas on how to make a hydraulic apparatus to cycle the port from zero to operating depth in my chamber? <br>
