High Voltage Glove Testing Frequency

Liner gloves reduce the discomfort of wearing rubber insulating.

High voltage glove testing frequency.

Our test facility offers comprehensive compliance testing for rubber insulated electrical gloves. Final inspection with a blow up air test. Lineman s testing laboratories adheres to testing procedures in accordance to astm f496. 1910 137 a 2 ii a if the ac proof test is made at a frequency other than 60 hertz the permissible proof test current shall be computed from the direct ratio of the frequencies.

The procedure should be repeated after turning the glove inside out. Certified blanket testing service charge class 00. Additionally 1910 137 provides specific design care and use requirements for rubber electrical protective equipment. Certified blanket testing service charge class 0.

If the insulating equipment has been electrically tested but not issued for service it may not be placed into service unless it has been electrically tested within the previous 12 months. Even if the gloves were not issued into service they still expire after 6 months and cannot be used until they have been tested. Check in wash and preliminarily inspection of insulating materials. Rubber insulating gloves classified by the level of voltage and protection they provide.

As stated in astm f 496 type i gloves should be expanded no more than 1 5 times their normal size during the air test and type ii gloves no more than 1 25 times. Rubber insulating gloves are to be tested before first issue and every 6 months thereafter. Certified electrical rubber insulating glove test service charge class 4. Basically the glove is filled with air either manually or with a power inflator and then checked for leakage.

A glove system consists of. Gloves should also be electrically tested following astm d120 14a and the international electrotechnical commission iec 60903 2014 standard. What we offer with your lineman gloves. Our rubber testing lab provides electrical glove testing services to astm d120 astm f496 standards.

Certified electrical rubber insulating glove test service charge class 3. Testing of high voltage gloves should be done every 6 months. Please refer to astm f496. High voltage insulating rubber glove testing.

Rubber sleeves are tested to astm d1051 astm f496 standards. Ltl recommends two pairs of insulating rubber gloves of same voltage class for testing rotation cycle to ensure a pair of electrical gloves are ready to go when you are. When the ac proof test is used on gloves the 60 hertz proof test current may not exceed the values specified in table i 1 at any time during the test period.
