Class 3 Gloves

Class 3 rubber gloves are rated to protect workers from electrical shock up to a maximum voltage of 26,500 volts AC (26.5kV) and 39,750 volts DC. 

Here's a more detailed breakdown:

Voltage Classes: Electrical-insulating rubber gloves are categorized by their maximum voltage rating, with Class 3 being designed for higher voltages. 

Class 3 Protection: These gloves are specifically designed to provide protection against electrical shock when working on or near energized equipment or lines with voltages up to 26,500V AC. 

AC Maximum Use Voltage: 26,500V 
AC Proof Test Voltage: 30,000V 
DC Maximum Use Voltage: 39,750V 
DC Proof Test Voltage: 60,000V 

It's crucial to select the appropriate class of gloves based on the voltage levels encountered in the work environment. 

ASTM Standards: Class 3 gloves are color-coded to meet ASTM standards per Glove Class. 
Testing: Each glove is visually inspected, inside and out, and electrically tested at its proof test voltage.
