Burglary resistance


Technical rooms are the heart of a building and an organization. Not only is it important to keep the technology running, but also to properly protect sensitive information and valuable machines and materials.


There is more to making a technical room burglar-proof than you think. JAZO offers the solution, because our burglar-resistant doors and grilles meet high burglary resistance classes. And best of all, no concessions are made in terms of ease of use. That gives you a safe feeling, right?

For years we have been strong in developing, producing and installing shielding, access and ventilation of technical areas. We have a suitable door and/or grille for every situation that meets all prescribed requirements. It is not without reason that we have been a partner of all energy companies and contractors in the Netherlands for many years.


We like to provide solutions that not only make us happy, but also make you happy. In this way, together we arrive at the most ideal solution, suitable for the situation. Do you want a single or double door? No problem! Just like many other options are possible.

For the burglary resistance of windows and doors, the Building Decree refers to the Dutch standard NEN 5096. This standard was written so that it can be used to determine the burglary resistance of homes, commercial buildings and renovation projects. According to the Building Decree, all windows or doors must meet at least burglary resistance class 2.

The Building Decree regulations do not prescribe anything for technical areas. Yet in practice we see that specifiers do include the regulations to meet at least burglary resistance class 2 in their specifications. Clients also often impose certain requirements when it comes to burglar resistance. Class 2 is too low for many rooms, so depending on the burglary protection level that is being achieved, the client can always request a higher burglary resistance class. And JAZO is prepared for that! Because we supply our doors and grilles from class RC-2 to RC-4 (Dutch term WK-2 to WK-4).


JAZO supplies doors and grilles of burglar resistance class RC-2 to RC-4 (Dutch term WK-2 to WK-4) that of course meet the applicable standards. The doors have been tested according to EN1627 and NEN 5096 standards. Our products are also KOMO certified (KOMO certificate) for both class 2 and class 3 burglar-resistant products. The production process is audited annually by the SKG, which guarantees our quality. The reports are assessed based on the latest applicable standards. If a report no longer meets the latest applicable standards, a burglary test will have to be carried out again.

Our doors and grilles are tested by the Gevelbouw Quality Foundation (SKG), a testing institute in the field of burglar-resistant products. SKG tests aluminum, steel and plastic windows and doors for burglar resistance with experienced inspectors. In addition, SKG has an advanced laboratory where hinges and locks products are also tested. We pay extra attention to the locks, which meet all applicable requirements according to the latest standards. For example, we use locks that are equipped with SKG ** or SKG ***, EN 179 (panic on the handle) and EN 1125 (panic on the beam) certificate.


The burglary tests can be tested based on two standards; NEN 5096 and EN 1627. Both standards indicate when a door is assigned a certain value. The higher the class, the more resistant the door is to burglary. For this purpose, the door or grille must pass three different tests:

Static test: this involves pressing with presses on each corner and the closing points (lock and hinges) of the door.
Dynamic test: a weight is allowed to strike the door three times, both in the center and in each corner of the door.
Manual test: this is a manual break-in attempt, where the differences are in the tools and the time required to break in.

  • RC2 / Wk2 / class 2 = 15 minutes test, of which max. contact time * 3 minutes
  • Simple tools, such as a large screwdriver, may be used.
  • RC3 / Wk3 / class 3 = 20 minutes test, of which max. contact time * 5 minutes
  • Heavier tools, such as a hammer and crowbar, may be used.
  • RC4 / Wk4 / class 4 = 30 minutes test, of which max. contact time * 10 minutes
  • Even heavier tools, such as a sledgehammer and bolt cutters, may be used.

* Contact time: time to open the door with tools

Do the test performers not arrive within this time? Then the test is passed.


In addition to the class system, SKG also has a star system. A system you may be familiar with.

But what is the difference between the class system and the star system? The star system only provides product certification, with the focus on the hinges and locks. The class system ensures a complete test, including hinges and locks. Exchange of locks is permitted, provided that the functionality is equivalent to the number of SKG stars.

Example: if a client requests hinges and locks with three stars, JAZO can also offer a door with a lock that is certified in class 3. The entire door has been tested, including the hinges and locks.


As mentioned earlier, we have a KOMO certificate for burglar resistance in class 2 and 3 for our products. This is a document in which SKG-IKOB declares that a product is suitable for use in construction according to building regulations. Something we are very proud of, but which also provides the necessary benefits:

  • Reports and declarations of conformity are valid against the current versions of the standards and BRL issued at the time. These lose their validity in the long term if there are changed standards and/or BRL. Certificates, on the other hand, are continuously monitored and are also adjusted after changes to the standards, BRL or building decree. If this happens, we must have our product tested again, so that it always meets the applicable requirements.
  • Compact and clear, with the aim of proving that the system, including hinges and locks, meets the required 'current' standards and BRL.
    Expansion possible in one and the same document.

An assessment guideline (BRL) is a standardized document on the basis of which SKG-IKOB assesses a specific product or process. The BRL not only contains the legally applicable requirements, but also the technical and aesthetic requirements imposed by market parties. KOMO quality declarations therefore go further than the (performance) requirements of the Building Decree alone.
