High Voltage Glove Testing Frequency

Lineman s testing laboratories adheres to testing procedures in accordance to astm f496.

High voltage glove testing frequency.

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. Gloves should also be electrically tested following astm d120 14a and the international electrotechnical commission iec 60903 2014 standard. Testing of high voltage gloves should be done every 6 months. High voltage insulating rubber glove testing.

Jm test systems is fully accredited for testing high voltage rubber protective goods. Insulating gloves and sleeves must be rated for the voltage to which a worker will be exposed phase to ground or phase to phase and marked to indicate their rating. Our test facility offers comprehensive compliance testing for rubber insulated electrical gloves. 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.

Certified electrical rubber insulating glove test service charge class 4. 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. 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. What we offer with your lineman gloves.

A glove system consists of. Liner gloves reduce the discomfort of wearing rubber insulating. Even if the gloves were not issued into service they still expire after 6 months and cannot be used until they have been tested. 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.

Additionally 1910 137 provides specific design care and use requirements for rubber electrical protective equipment. Final inspection with a blow up air test. Please refer to astm f496. Rubber insulating gloves are to be tested before first issue and every 6 months thereafter.

Rubber sleeves are tested to astm d1051 astm f496 standards. Certified electrical rubber insulating glove test service charge class 3. Check in wash and preliminarily inspection of insulating materials. Certified blanket testing service charge class 00.

Basically the glove is filled with air either manually or with a power inflator and then checked for leakage. Voltage rated rubber insulating gloves that have been previously issued can be used safely for 6 months after the test date at which time the gloves will need to be sent back to an approved lab for dielectric testing. Certified blanket testing service charge class 0.
