BURGLAR RESISTANCE
Burglar resistance is the description used to define products and components which are designed to prevent unwanted entry into an area. These products are described as burglar resistant.
Special DIN classes, known as resistance classes WK1 – WK6, have been created to differentiate between these products. These classes are ascertained using test procedures, in which break-ins are simulated with a variety of different perpetrators. This person is equipped with different implements, depending on the class and has a certain time e.g. to break open a test door. If he does not succeed, the door has passed the test procedure and is certified to the appropriate class.
List of the resistance classes as per European Standard DIN V EN V 1627 – 1630 from April 1999 and their associated technical requirements:
| Resistance Class: | Security Door Plates DIN 18257 | Lock Cylinder DIN 18252 | Glazing DIN EN 356 | Test Cert | Perpetrator and method | Manual Test Time DIN V ENV 1630:
DIN V EN V 1630: |
|---|---|---|---|---|---|---|
| WK1 | ES 1 | P2 BZ | Composite glass recommended | Not required | Vandalism: Kicking, pressing, jumping against. Little protection against levering |

| WK2 | ES 1 | P2 BZ | P4 A | Required | Opportunist: Bodily force, simple tools e.g. screwdriver, shim, pliers |
3 - 15 mins |
| WK3 | ES 2 | P2 BZ | P5 A | Required | Opportunist: With add’l second screwdriver and crowbar |
5 - 20 mins |
| WK4 | ES 3 | P3 BZ | P6 B | Required | Experienced perpetrator: Add’l use of saw and tools such as axe and chisel, hammer, electric drill |
10 - 30 mins |
| WK5 | Individual test | Individual test | P7 B | Required | Experienced perpetrator: Add’l use of electric tools, such as drill, jigsaw or saber saw |
15 - 40 mins |
| WK6 | Individual test | Individual test | P8 B | Required | Experienced perpetrator: Add’l use of more powerful electric tools than WK5 |
20 - 50 mins |
ATTENTION:
Under examination of glasses' burglar resistance is tested, if an offender (in a period of time determined by the norm) succeeds in creating an opening in a size of 50 x 50 cm, through which he is able to get into the building.
However, it is possible to do this even more rapidly by breaking a small opening into the glass to reach through with a tool or by hand and use the handle inside.
Thus, SITEC recommends:
Burglary-resistant casement windows have to be equipped with lockable handles.
Doors have always to be locked, the key should not stuck inside.
The automatic door-opener is always opening the bolted door-lock for burglary-resistant doors with the function of escape route and panic.
The glazing of doors is in accordance with the demanded test category insufficient.
The door-opener can be used easily by the hole inside the glazing (see photograph) - the door is opening - the resistance class is not reached.
Such doors need special-purpose glass!
