This standard specifies the limit value of the voltage level of the I section defined in GB/T 18379, which is used to guide the correct selection of the human body to use various electrical equipment under normal and fault conditions, and to touch and conduct electrical equipment under various environmental conditions. The voltage limit of the part. After considering some important factors, each professional standardization technical committee may select a voltage limit value other than this standard if experience shows that a reasonable safety level can be achieved. This standard does not address voltage levels for patient contact in medical applications. This standard does not deal with any insulation system or method of protection. Conventional touch voltage limits for automatic power cut-off defined in IEC 60050-826 are outside the scope of this standard.
