On October,22 2015 there were performed tests of protected object of the checkpoint type manufactured by the group of companies ”Modul” (Kameshkovo, Vladimir Region). The “MODUL500BB/3” checkpoint successfully passed tests for explosion resistance. This was confirmed by Certificate РОСС RU.МЛ25.Н01236. The Certificate was issued by the “MEGASERT service” certification authority (Moscow).

The private Russian company has finished a great work in the development and production of the protected objects having the unique safety-providing characteristics.

The ”Modul” group of companies was given a new certificate of its product conformity with the safety requirements and once again the company confirms that it actually occupies the leading position in production of the safety-providing objects and armoured glasses in Russia. It is important to note that for manufacturing its products the MODUL company uses only the Russian-made materials and components.


In the “MODUL500BB/3” checkpoint under test digit 3 at the end of its designation indicates its bullet-resistance class.

To meet the customer’s requirements the Modul group of companies can make the checkpoint objects having the protection Classes from 3 to 6 inclusive (GOST Р51112-97).

Director of the “MODUL” group of companies Sergei Kuznetsov:
The successful tests for explosion resistance of the “Modul 500BB 6а”checkpoint allows to extend the results of the explosion tests over the higher bullet-resistance classes including the highest one-Class 6a.

To our opinion, the most up-to-date product is actually the Modul 500BB/5 checkpoint. This bullet-resistance class corresponds to the most popular small arms models.

The production facilities and equipment make it possible to produce the serial checkpoints having the bullet-resistance class 5with the corresponding certificates for the bullet- and explosion- resistant checkpoints.

B –guard room (protected room)

In the client entrance room:
A1- door of entrance security cabin
A2 – protected exit door for personnel and clients after their successful passing the checkpoint
A3 – points of test demolition (outside and inside the room)
A4 – blast shock wave sensor

In the protected room (guard room):
B1 – protected door (guard entrance/exit door)
B2 – blast shock wave sensor
B3 –window with armoured glass for handing-over the documents and assets

According to the approved testing program the checkpoint sample was tested by two burglary attempts – two TNT demolitions 0.5 kg each.

Below you can find the photo and video reports on testing the Modul 500BB/3 checkpoint for explosion resistance.

Test 1. Outer Explosion

Preparation. View from the side of the guard entrance

Preparation. View of the armoured glass with the tray from the protected room

For the 1st test there was arranged 0.5-kg TNT charge outside the checkpoint from the side of the non-protected door of the customers room at a height of 1m and at a distance of 0.5 m from the door.

Preparation. View of the TNT charge for demolition

After checking the TNT charge condition, all the doors were locked and the people present at the tests were evacuated to the safety distance.

The visual inspection of the whole object after the initial (external) demolition did not reveal any structure damages or deformations on the side opposite to demolition.

The visual inspection of the object from the side of demolition revealed no deformation or destruction except for the broken stand for the charge arrangement and carbon deposit left after explosion on the door outer surface.

The non-protected room inside (behind the door of the place of demolition) remained intact and was not affected by explosion.

After outer demolition. View of the armoured glass inside the room located at the maximum close distance from the point of demolition. The glass checking for integrity.

For those who cannot imagine the 0.5-kg TNT yield it will be interesting to know that at a distance of 60 m from the opposite side of the explosion point the jeans are pressed by the blast shock wave to the person’s legs.

TEST 2. Inside Demolition

Preparation to the 2nd test included the mounting of the 0.5-kg TNT charge inside the non-protected in the specified point: 0.5 m from the protected door at a height of 1m from the floor.

Preparation for inner demolition. View of the TNT charge in the demolition point from the protected room.

The power of explosion inside the room gains due to the energy release from the enclosed space.

Now it is just the time to describe the test which the “Modul” checkpoint has passed before.

After explosion, the air is ejected from the explosion center under high pressure at a high speed. As a result in the explosion center there is generated the vacuum-like state. The next moment with the same explosive response the air tends to fill this empty space.

In the previous tests due to this effect the protected door was bent inside and the outside door was torn out. After that the designers of the company carried out very serious work in the updating of the new model of the checkpoint.

The previous tests showed the company’s designers and managers the importance of thorough examination and analysis of any abnormal deformations. As for the tests carried out on 22.10.2015, they proved that the step-to-step updating of the product together with the experiments on the real specimens allowed to create a really protected object.

The white strips fallen out of the doorframe were the sealing elements of the protected door. The “vacuum” effect drew the door inside by 0.4 mm along the overall length of the door but in this case the door hinges were not broken, the door was not bent, the door locks and the lock rods were not broken. There was only revealed the frame profile bending in the lock area.

After the charge demolition the structure elements were not broken. Only some cracks occurred on the armoured glass surface. The wooden fragments on the floor are the pieces of the stand on which the charge was mounted.

The evaluation of the condition of the armoured glasss from the side of the guard room showed that the cracks in the multilayer protected armoured glass had no effect on the layers located from this side of the room. The more careful analysis and the readings of the blast shock wave sensor did not reveal inside the protected room the results of the explosion effect or the secondary effect of the injuries caused by the armoured glass fragments, because the armoured glass itself preserved its integrity.

The best way to be sure in something is to touch this, if possible, with one’s own hands -it was possible to touch absolutely smooth glass.

The protected door for leaving the safety cabinet after successful passing the checkpoint (when looking from the room) is in the same condition as before the explosion except for the explosion “marks” on its surface and slight play in the lock area.

On the base on this Certificate the “Modul” group of companies has started production of the new models and their mounting at the customer’s place.
