What are the requirements based on?
It is clear that all standards for dielectric gloves are not taken from the ceiling. When it comes to working with high voltage installations, there can be no gaps, because they can cost human life. Before being put into operation, dielectric gloves undergo very important and difficult tests. The main test is considered to be immersed in energized water. They are immersed in water so that it is both outside and inside, but at the same time the upper edge of the sleeve remains dry. Then a current is passed through the water, and special devices measure the level of voltage passing through the protective layer. If the indicator is too high, they will not be allowed for sale and will be sent to marriage.
As for the length of the gloves, it should be such as to completely protect the hands of the electrician from stress, but at the same time not interfere with his work.
Features of choice and use
Safety and usability are the main criteria for choosing dielectric gloves. Also, manufacturers take into account other consumer needs and produce various sizes of these products.
The length according to GOST is 350 mm, and this is a characteristic feature of certified products. Dielectric gloves must sit on your hands so that you can put on one more warm gloves inside. In special working conditions, special leather gloves can be worn on top to increase durability.
High-quality gloves are completed with a data sheet, which indicates all the physical parameters of the products and the required conditions for normal use. Choose gloves based on the recommended protection class of products and the nature of work on electrical equipment. Such gloves are widely used in various enterprises and municipal organizations.
Gloves are visually inspected each time for possible surface damage prior to use. You can also knead them with a little effort to reveal imperfections or cracks. To identify punctures, you can twist the products from the bell to the fingers.
The tightness can be checked in a simple way: fill with air, then squeeze a little. In the event of damage to the product, the defects will be immediately noticeable. This is necessary to exclude the passage of current through holes and punctures.
The products used for work are regularly washed from contamination with solutions of ordinary soap or baking soda. You need to dry them indoors, but not on a battery.
For dielectric latex gloves, conductance tests are required strictly according to the schedule established by the instructions. To test the product, place it with your fingers down in a metal container with water at room temperature. A deviation in one direction or another of 100 is possible. Water must also be poured into the gloves, and the upper edge of the sockets is left dry at least 5 cm from the edge.
An electrode must be placed in the glove; a voltage of 6 kV is applied to it. It is allowed to test several pairs of gloves at the same time, the main thing is that the electric current values are monitored. If there is a breakdown of the product with an electric current, then the glove must be disposed of. In other cases, the values of the passing current are measured, while it should not exceed the norm of 6 mA.

What documents regulate the production
Basically, manufacturers are guided in the manufacture of dielectric gloves GOST 12.4.183-91 "Materials for hand protection." Technical requirements". According to this document, for example, gloves for electricians should be made exclusively from natural rubber.
Does not regulate GOST only issue seam gloves... When manufacturing such products at enterprises, they are guided by the provisions of TU 38305-05-257-89. Such products are made from pieces of rubber sheet by punching.
Such products are classified according to GOST 12.4.103-83. Dielectric gloves, according to this document, are reusable products.
Other rules and regulations must be observed in the manufacture of protective equipment. For example, according to GOST 12.4.252-2013, dielectric gloves should be easy to manipulate with your fingers. The degree of freedom of movement of the latter is determined by a special table.
Of course, not only dielectric gloves are manufactured in compliance with certain standards. GOST 13385-78 regulates, for example, the manufacture of shoes for electricians. In compliance with the standards stipulated in this document, boots, galoshes and boots are manufactured.
Thus, according to GOST, footwear for electricians, as well as rubber, silicone, and dielectric seamless gloves made of latex. GOST 4997-75 is another document regulating the production of protective equipment. According to the regulations, rubber and silicone mats are made from this document.
Requirements for dielectric gloves
There are two types of isolating protective equipment: basic and additional. If the master works on an electrical network, the voltage of which does not exceed a thousand volts, then dielectric gloves are considered the main means of protection. In networks with voltages over a thousand volts, such gloves are used as an additional means of protection.
Dielectric gloves are also divided into two types. There are gloves made from seamless latex. There are also gloves made of rubber sheet, there is a seam on these.
If you use gloves that have a seam, always pay attention to the quality of the seam, as the seam is the weakest point of these gloves. If the manufacturer cheated, then your gloves can play an evil service, therefore, before using protective equipment, be sure to check your gloves.
Yes, and this should be done regularly.

How long should dielectric gloves be? According to SO 153-34.03.603-2003 "Instructions for the use and testing of protective equipment used in electrical installations" the length of dielectric gloves must be at least 350 millimeters, and the size must be such that this rubber glove can be worn over a regular cotton one. The width should allow you to hide the sleeves of clothes in such gloves.
There are two main important requirements for the operation of dielectric gloves:
- 1. Gloves must be clean and dry. This is a must.
- 2. Not be damaged. Be sure to check the integrity of the gloves before work, the slightest hole can be fatal.
Now a few words about why dielectric gloves should be worn loosely on the hand. In winter, working with rubber gloves alone is very uncomfortable. Therefore, you can safely wear warm gloves under them to avoid frostbite of your fingers.
Since rubber itself is a rather fragile material, you can wear tarpaulin or leather gloves on top. This will help to avoid quick damage / wear of the rubber gloves.
In no case should you roll up the edges of your gloves. After work, gloves must be washed and dried.
