High Voltage Glove Testing Frequency

Gloves should also be electrically tested following astm d120 14a and the international electrotechnical commission iec 60903 2014 standard.

High voltage glove testing frequency. 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. Certified electrical rubber insulating glove test service charge class 4. Additionally 1910 137 provides specific design care and use requirements for rubber electrical protective equipment. Check in wash and preliminarily inspection of insulating materials.

The procedure should be repeated after turning the glove inside out. Certified blanket testing service charge class 00. Rubber sleeves are tested to astm d1051 astm f496 standards. Certified blanket testing service charge class 0.

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. Rubber insulating gloves classified by the level of voltage and protection they provide. Rubber insulating gloves are to be tested before first issue and every 6 months thereafter. 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.

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. Our test facility offers comprehensive compliance testing for rubber insulated electrical gloves. Lineman s testing laboratories adheres to testing procedures in accordance to astm f496. Certified electrical rubber insulating glove test service charge class 3.

Basically the glove is filled with air either manually or with a power inflator and then checked for leakage. Even if the gloves were not issued into service they still expire after 6 months and cannot be used until they have been tested. 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. Final inspection with a blow up air test.

Our rubber testing lab provides electrical glove testing services to astm d120 astm f496 standards. What we offer with your lineman gloves. 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.

Please refer to astm f496. Liner gloves reduce the discomfort of wearing rubber insulating. High voltage insulating rubber glove testing.
