What is the AC retest voltage for Class 4 rubber gloves?

The correct AC retest voltage for Class 4 rubber gloves is 40,000 VAC. This voltage level is specified for Class 4 rubber insulating gloves, which are designed to protect workers from electrical hazards. Class 4 gloves are tested to withstand higher voltages because they are intended for use in environments where there is a significant risk of exposure to electrical shock from high-voltage equipment.

The retest voltage is an important safety measure, as it ensures the integrity and reliability of the insulating properties of the gloves. Regular testing at this voltage helps in identifying any potential damage or degradation, ensuring that the gloves provide the necessary protection when used in the field.

The other voltage levels listed correspond to different classes or types of rubber gloves, which are suited for lower voltage environments and do not meet the requirements needed for Class 4 gloves.
