For flammability apply UL 746C depending on proximity to ignition sources. Also simulate leaks or hose coming off the connections. If there is a risk of shock as a result of the hose leaking you may wish to redesign by having some form of barrier or double fixation method. Best Regards Sent

I spent a lot more time with water cooling in the data center at my former employer, APC/Schneider Electric. Most cooling water in data centers is either in metallic pipes or cross-linked polyethylene (PEX). PEX is also the material used for applications such as radiant under-floor heating and
