Test of dielectric gloves

Any electrical installation is a danger to a person. In production, employees are obliged to use special protective equipment, including gloves. It is they who allow to protect against shock. In order for the tool to perform the tasks assigned to it, it will be necessary to check for integrity and, if necessary, replace new.

Test Methods

If the head is responsible to the issue of ensuring the proper level of security at the enterprise, it will not save on the means of protection for his staff. Before use, dielectric gloves should be tested for integrity and test test. It is they who determine the shelf life of the product and the possibility of further use.

Use dielectric gloves at installations up to 1000 V.

They can be made of natural rubber or leaf rubber. It is necessary that the length is at least 35 cm. Gloves used in electrical installations can be both sutured and seamless.

Also, the legislation does not limit the use of bibgled products on a par with five plates. It is allowed to use only those products on which there are marked:

  • EV;
  • En.

Special requirements are available to product size. So, gloves must accommodate the hand to which the knitted product, protecting the fingers from the cold. The width of the edge should allow pulling the rubber product on the sleeves of the existing outerwear.

Test of dielectric gloves

Safety tested gloves strictly prohibited.

It is impossible to do this and during the test for the presence of defects. It is desirable that water in the container, where the product is immersed, was about + 20 s. Cracks, breaks and other visible mechanical damage is not allowed. If they are, then you need to buy new gloves. Electrical Installation – Equipment not tolerant of negligent relationship. Any non-compliance with safety requirements will lead to an accident.

    Legislative acts are clearly registered when there is a test of dielectric gloves. Such an inspection is necessary no later than 6 months after commissioning means of protection. To test the product, you will need a bit of things, so such a check is available to each enterprise.

    It is important that a qualified specialist with due qualifications and must be engaged in the process.

    Necessary things

    Only dielectric gloves that have no visible damage can be subjected to test. To do this, make a laboratory specifically. More qualitative result can be achieved only when testing in water. In this way, you can easily reveal even small damage.

    To conduct a check, it will be necessary to prepare a bath, filled with liquid, and electrical installation.

    Voltage

    To ensure the cleanliness of the check, it will be necessary to ensure the electrical installation of the required voltage. It is usually at 6 square meters. On the maximummeter used, the value should not rise above the 6 mA mark. Each pair is tested by no more than 1 minute. Initially, the position of the electrical installation lever must be in position. This is how you can check whether there are trifles in gloves. To do this, use signal lamps indicators. If everything is fine, the lever can be translated into. This measure the current flow occurring through the glove.

    In the event that the lamp begins to signal about the existing test, the test is completed. The glove is considered defective and cannot be used.

    If everything went fine, before entering into operation, the means of protection is first dried, Then they apply a special stamp, which indicates tests. Now the product can be deposited or to issue employees.

    Process

    Not everyone understands, for what you need to experience dielectric gloves, as they probably passed the check in the factory. Moreover, in six months you can just buy a new kit. In fact, there is an instruction on the use and testing of protection. This document is called from 153-34.03.603-2003. According to clause 1.4.4, the means of electrical cavity obtained from the manufacturer’s factory must be checked directly at the enterprise where they will be used.

    It is very important to understand that if at the time of the inspection it turns out that the current is passed through the product above the value of 6 mA, it is not suitable for use and is only subject to writing as marriage.

    1. Gloves will need to first lower the water bath filled with water. At the same time, their land should look out of water at least 2 cm. It is very important that the edges are clean and dry.
    2. Only after that contact from the generator can be lowered into liquid. At this very time, the other contact joins the grounded surface and falls inside the gloves. As part of the test used ammeter.
    3. It’s time to feed the voltage on the electrode in the bath. Data is written off an ammeter.

    If the check is carried out correctly, it is easy to prove the suitability of the dielectric. Any violation may cause an error, and afterwards an accident.

    When everything is completed, the protocol is drawn up. The data obtained contribute to a special magazine, designed to control the frequency of research.

    Dry gloves after checking it is necessary to indoors with room temperature. If this requirement does not follow, then low or high temperature will cause damage to the appearance of damage, which, in turn, lead to dissent.

    In some cases, extraordinary tests of gloves are required.

    This happens after the repair work, replacing the electrical installation parts or when malfunction is detected. External inspection of products required.

    Terms and frequency

    Periodic inspection of groves made of rubber or rubber, according to the rules, is carried out once in 6 months, this period does not take into account unscheduled tests. It does not matter whether all this time is exploited or lay in stock. Such a check is set for rubber gloves regardless of the degree of their use in the enterprise.

    This approach allows you to identify defects that can lead to an accident. Often checking gloves at the factory there is no possibility – then third-party laboratories have a special license.

    Test of dielectric gloves

    Specifically, rubber dielectric gloves are tested only by a current, despite the fact that other testing methods are used for various protection tools. When conducting a procedure, the presence of a licensed specialist who can estimate the results obtained during the inspection. Almost everyone who belongs to the electrical personnel undergo a re-exchange, within which questions are asked for methods and timing of dielectric gloves.

    Remember information is very simply on the question under consideration, since the rule of 4 Sixer is valid. Tests are carried out with a periodicity of 6 months, the voltage supplied to the product is 6 kV, the maximum allowable rate of the current is 6 mA, and the duration of the inspection is 60 seconds.

    What to do if the gloves have not passed the check?

    It happens that checking the product did not pass in the first or second stage. That is, with an external inspection or when conducting current. It does not matter the reason why the gloves did not pass the test. If they are rejected, then they should always come with them equally.

    On gloves of red paint, the existing stamp is covered. If there were no earlier checks, and it was not put, then the red line is simply held on the product.

    Such protection means are made of exploitation, store them in the warehouse is also prohibited.

    Test of dielectric gloves

    Each enterprise, where electrical installation is obliged to follow the special instructions. It is this document that is intended to regulate the procedure for follow-up.

    Laboratory testing, tested, stores where information on the results of previously conducted inspections fit. It is called “Journal of Testing Tests of Dielectric Rubber and Polymer Materials”. There is also a corresponding marker about the unsuitable pair. Products at the end are disposed of.

    It should be understood that the presence of gloves in the warehouse to be disposed of may cause an accident.

    Human inattention often leads to sad consequences, which is why utilization is made immediately after identifying a defect and making relevant information to the magazine. At each enterprise there is a responsible person, whose duties include conducting timely inspections.

    If the electrical installation was carried out repair work or replacement of structural elements, then checking the gloves for integrity is carried out unscheduled. So it is possible to remove unsuitable protection tools in a timely manner, and, accordingly, and avoid accidents.
