IEC 62610-4:2013 specifies the test setup and test parameters for water supplied heat exchangers within single electronic cabinet configurations. The tests are focused on cabinets for the installation of high power dissipation electronic equipment. The cabinets concerned are from the IEC 60297 (19 in) and IEC 60917 (25 mm) series. The purpose of this standard is to provide comparable data for the cooling performance of cabinets according to defined test setups and cooling parameters. Key words: Electronic cabinets, cooling, water supplied heat exchangers
