3 Medical Location Classification
3.0.1 Medical locations shall be classified into the following three categories according to the electrical safety protection requirements:
1 Category 0: the medical location where the contact part of medical electrical equipment is not used;
2 Category 1: the medical location where the contact part of medical electrical equipment is required to touch the surface or inside of the patient body (except the parts stated in Category 2 medical location);
