Scope

This Standard gives guidance on the selection of voltage classes within Band I, as
defined in GB/T 18379, for conductive parts that may be touched by human beings in
various applications and environmental situations under both normal and fault
conditions.
After taking into account the significant factors, professional standardization technical
committees may select voltage limit values other than those given in this Standard, if it
is shown by experience that a reasonable safety level can be achieved.
Voltage classes for patient contact in medical applications are not covered by this
Standard.
This Standard does not include any reference to insulation systems or to methods of
protection. The conventional touch voltage limit value as defined in IEC 60050-826 for
the purpose of automatic disconnection of the supply is not within the scope of this
Standard.

Summary	This standard specifies the GB/T 18379 �� defined in section limits the voltage level to guide the correct choice of two kinds of human body in normal and fault conditions using a variety of electrical equipment, and in a variety of environmental conditions can be touched conductive parts of the voltage limit. The Standardization Technical Committee in considering a number of important factors, such as experience shows that to achieve a reasonable level of security, you can select the standard voltage outside limits. This standard does not involve the medical use of patient contact with the voltage level. This standard does not involve the medical use of patient contact with the voltage level. This standard does not involve any insulation system or protection methods. Defined in IEC 60050-826 automatically cut off power supply using conventional touch voltage limit is not the scope of this standard.
