Tech/Engineering - Electronics / Elect Eng / medical equipment | | English term or phrase: shock protected Class 1, Type B applied part | "IEC60601-1, CSA C22.2 No 601.1. and UL2601-1, shock protected Class 1, Type B applied part"
Does Class 1 refer to the part (rather than shock protection) and what exactly is "applied part", is it an attachable device ?
The text refers to a medical (dental) device |

Applied Part: Type B, BF or CF
IEC 60601-1 uses the term applied part to refer to the part of the medical device which come into physical contact with the patient in order for the device to carry out its intended function.
Applied parts are classified as Type B, Type BF or Type CF according to the nature of the device and the type of contact. Each classification has differing requirements from the point of view of protection against electrical shock.
Type CF is the most stringent classification, being required for those applications where the applied part is in direct conductive contact with the heart.
Type BF is less stringent than CF, and is generally for devices that have conductive contact with the patient, or have applied parts that are fixed in medium or long term contact with the patient, e.g. ECG electrodes.
Type B is the least stringent classification, and is used for applied parts that are generally not conductive and can be immediately released from the patient.
Type B applied parts may be connected to earth, while Type BF and CF are 'floating' and must be separated from earth.
Although IEC 60601-1 doesn't stipulate which classification is to be used for specific devices, the particular standards, IEC 60601-2-XX, generally do specify which classification is required.
More details of electrical requirements for applied parts are provided by the articles on circuit separation and leakage currents.
