The medical standard IEC60601-1 defines three types of applied parts, parts of the equipment that comes into contact with the the patient under normal operating conditions. Type CF, or Cardiac Floating, parts have the most stringent classification as they are parts that may come into direct contact with the heart. Type CF (cardiac floating) are floating with respect to earth. The main difference between B and BF category power supplies and CF is The patient leakage current. The patient leakage current is the current flowing from the applied part via the patient to earth as a result of an unintended voltage from an external source on the patient. The limit, or maximum amount allowed is 10 uA for CF.
