Protective Industrial Products, Inc recently released this resource highlighting common questions surrounding rubber insulated electrical gloves.


What standards do your gloves meet?
Novax® Industrial branded gloves are manufactured to meet or exceed the requirements of the current version of ASTM D120, the standard specification for Industrial Rubber Insulating Gloves.

Why should I use the Novax® brand of insulating gloves?
Novax® insulating gloves are manufactured in Malaysia using an environmentally friendly aqueous dip process. The natural rubber raw material is kept in its natural aqueous state, as opposed to the solvent dip process used by other manufacturers which uses extensive amounts of volatile organic compounds (VOC’s). Our gloves retain more of the beneficial physical properties of natural rubber which is demonstrated in the physical property tests required in the ASTM D120 testing requirements.
▪ Ergonomic Design
▪ Hand at a Natural Rest Position
▪ Wrist is straight, not cocked back at an unnatural 30 degree angle
▪ Fingers are aligned in natural position, not spread out.
▪ Fingers are slightly curved forward.
▪ Improved Dexterity
▪ Low Modulus Formulation
▪ Cuff flare is angled between that of Salisbury and White Rubber products
▪ Improves air flow and comfort (in warm climates)
▪ Exceed ASTM D120 requirements
▪ Physical test results
▪ Electrical test results

Novax Rubber Insulated Gloves

How do I know what glove to use?
First you should determine the maximum voltage that you will be exposed to during your work. Once you have determined the risk, you can use the chart below to determine the appropriate class of glove that will provide you the protection required to compete your job safely. Each class of gloves is clearly marked with the maximum use voltage on the permanent color coded label.

How do I determine what size of glove is right for me?
ASTM D120 section 8.2 provides the measurements of the diameter of the palm for manufacturers, measured at the midpoint of the palm, plus or minus ½”. Measure your hand and the number of inches in diameter of your palm would equate to the probable size of glove to select. Personal preference for tightness and finger length will ultimately determine the size that you are most comfortable wearing.

Glove Sizing

What size of leather protector should I use?
Leather protectors should always be worn with rubber insulating gloves. ASTM F696 provides the specification for the manufacture of Leather Protectors. Leather protectors are sized to be worn on the same size rubber insulating glove so if you wear a size 10 rubber insulating glove you should order a size 10 leather protector.

When should leather protectors be used?
Under most circumstances leather protectors should be worn unless the dexterity required to perform the task requires that rubber insulating gloves are worn alone. OSHA has specific requirements associated with the use of protectors and the end-user is responsible to make sure they are in compliance. But remember that a leather protector alone does not provide any electrical insulating protection.

What length of leather protector should I use?
In the ASTM standards specifying the characteristics of the protectors there are regulations on how much of the rubber glove can be exposed at the top (near the cuff.)  Due to this, certain leather protectors are used with specific classes of rubber gloves according to their length. The protectors are not interchangeable with the different classes of rubber gloves.
• Class 00 & 0 should have no less than a ½” gap between the top of the insulating glove to the top of the leather protector.
• Class 1 should have no less than a 1” gap between the top of the insulating glove to the top of the leather protector.
• Class 2 should have no less than a 2” gap between the top of the insulating glove to the top of the leather protector.
• Class 3 should have no less than a 3” gap between the top of the insulating glove to the top of the leather protector.
• Class 4 should have no less than a 4” gap between the top of the  insulating glove to the top of the leather protector.

How are Novax®  gloves electrically tested?
The manufacturer of Novax® gloves electrically tests every glove prior to shipment. Each “batch” of gloves is also subjected to a battery of physical and electrical tests to insure that the gloves meet the D120 Standards. It is the responsibility of the employer to insure that the gloves have passed the required electrical test within the specified time.

How long does the user have to put new gloves into service?
The user has 12 months from the test date to put new gloves into service. New (gloves that have never been issued for use) may be retested and the user has 12 months from that date to put them into service.

When should rubber insulating gloves be retested?
There are two standards that prescribe test intervals:
• OSHA 1910.137 – Must be electrically tested before first issue and every six months thereafter
• OSHA 1910.268 (Tele-com) – Natural rubber insulating gloves must be electrically tested before first issue, twelve months after
first issue and every 9 months thereafter
• Any un-issued glove that has not been tested within twelve months must be re-tested before issue.
