Dear Group, Medical devices frequently include an equipotential terminal. It is used to ensure that all devices connected simultaneously to a patient are referenced to the same earth potential, otherwise any differences can cause a current through the patient.
Does anyone know the standard which specifies the mechanical structure of this terminal, in particularly whether the yellow/green disc, which is usually placed around the terminal, is a mandatory part of the specification? A colleague claims that the yellow/green disc is not necessary. Please note that the answer is NOT is IEC 60601-1, which just specifies the marking which is required adjacent to the terminal, but does not specify the form of the terminal itself, or when it should be used.
