what is the AC max use voltage of these gloves?

Class 2 rubber insulating gloves are proof tested at 20000VAC, what is the AC max use voltage of these gloves?

Hope this helps you out



Voltage protection is broken down into the following classes:
•Class 00 - Maximum use voltage of 500 volts AC/proof tested to 2500 volts AC
•Class 0 - Maximum use voltage of 1,000 volts AC/proof tested to 5,000 volts AC
•Class 1 - Maximum use voltage of 7,500 volts AC/proof tested to 10,000 volts AC
•Class 2 - Maximum use voltage of 17,000 volts AC/proof tested to 20,000 volts AC
•Class 3 - Maximum use voltage of 26,500 volts AC/proof tested to 30,000 volts AC
•Class 4 - Maximum use voltage of 36,000 volts AC/proof tested to 40,000 volts AC

Rubber insulating gloves are available in six ASTM defined voltage classes. Rubber insulating sleeves are available in Class 00 through 4. The chart below identifies the class, proof test voltage and maximum allowable exposure voltage for Salisbury Linemen’s Natural Rubber and SALCOR Rubber Protective Equipment. (https://www.salisburybyhoneywell.com/en-US/utility/hand_arm/sleeves/Case%20Studies/gloves.pdf)


Class 00 (Beige) are proof tested at 2,500 AC / 10,000 DC and have a max use voltage of 500 AC / 750 DC
Class 0 (Red) are proof tested at 5,000 AC / 20,000 DC and have a max use voltage of 1,000 AC / 1,500 DC
Class 1 (White) are proof tested at 10,000 AC / 40,000 DC and have a max use voltage of 7,500 AC / 11,250 DC
Class 2 (Yellow) gloves are proof tested at 20,000 AC / 50,000 DC and have a max use voltage of 17,000 AC / 25,500 DC
Class 3 (Green) gloves are proof tested at 30,000 AC / 60,000 DC and have a max use voltage of 26,500 AC / 39,750 DC
Class 4 (Orange) gloves are proof tested at 40,000 AC / 70,000 DC and have a max use voltage of 36,000 AC / 54,000 DC


*Max use voltage when worn with leather protectors.

Also keep line-to-line voltage in mind when selecting rubber gloves.

Looks like Slice beat me to it! I posted a printable chart here -> http://testguy.net/threads/1464-Protective-Rubber-Equipment-Voltage-Ratings-and-Labeling-Chart

Yes , good chart. The colors are important to know as well.

This really helped

you can find all the class specifications in NFPA 70 E.

Don't forget about inspection and testing:

Gloves and sleeves must be electrically tested before being issued for use. They must also be visually inspected and gloves need to be air tested for any possible defects (for example, cuts, holes, tears, embedded objects, changes in texture) before each day's use and whenever there is a reason to believe they may have been damaged. Best practice is to inspect PPE and air test the gloves and sleeves before each use.

In addition, the gloves and sleeves must be electrically tested at regular intervals of not more than 6 months for gloves and 12 months for sleeves. When gloves and sleeves are used regularly, best practice is to test as frequently as monthly.

Rubber blankets are tested annually.

do rubber blankets have the same ratings as rubber gloves?

[cjones09]

Rubber blankets follow the same ASTM classifications as gloves and sleeves. The only difference is that blankets aren't required to be color coded.


do rubber blankets have the same ratings as rubber gloves?

Google it...or anything else for that matter...

I think just as important is the length of the keepers. Pretty easy to remember 1" per class 0 and 00 start at 1/2"
