To test leakage current, use a clamp meter or an insulation resistance tester. IEC60601-1 is mainly intended for product development where safety considerations must be taken into account early in the design phase of a. . Note: If leakage current tests do apply, could you clarify if they follow clause 8. 6 (ME equipment or ME system) when these equipment are connected to my device. Thank you in advance! Any parts of a "ME system" within the "patient environment" (a defined term) should comply with the. . Engineers and safety professionals use Hipot testers to perform accurate leakage measurements. Vitrek provides Hipot testers that can detect anomalies down to picoamp levels, ensuring comprehensive safety validation across diverse applications. So what's the problem? On circuits protected by GFCIs (Ground Fault Current Interrupters), leakage. . Most modern PAT instruments carry out a leakage test as part of their auto test sequences, however it's not a test required by the IET Code of Practice, rather it is intended to be used as an alternative, or in addition to the insulation test. Leak testing electrical vehicle battery cells, for example, begins with an ionic leak test of the battery cell pouch and ends with pressure leak testing the entire battery tray. In e-mobility applications. .
