The Resistance Classes According to EN 1627

28.10.2021

Most countries in Europe implement the European standards: EN1627, EN1628, EN1629 and finally EN1630. These standards describe different aspects of the regulations. 

The EN 1627-1630 standards offer a classification system made up of six categories and describe the test methods used to evaluate the resistance of these components subjected to static and dynamic loading, as well as to manual forced entry attempts.

Standard EN 1627 describes the test conditions and resistance classes.

The tests take place in three stages:

  1. Resistance to static loading (EN 1628)
  2. Resistance to dynamic loading (EN 1629)
  3. Resistance to manual burglary attempts (EN1630)

Standard 1627 describes the means used (force, tools, length of time, etc.) in manual burglary attempts to:

  • succeed in opening the door
  • or create an opening through which elements of specific dimensions can be passed (man hole)

During this test, a different tool set for each class is made available to the ‘attackers’. The attackers can use this and all the other tools listed in the lower classes.
The contact time defined per class is the length of time during which the tools are in contact with the door.
The total test time includes the contact time, rest time, observation time and ‘tool change’ time.
The attackers have the opportunity to study the plans of the door tested in advance to determine the potential vulnerabilities through which they could enter. This gives them a considerable advantage over an actual assault situation.

 

Resistance Class RC2 

Casual criminals use simple tools such as screwdrivers, pliers or wedges.

The amateur burglar, also using basic tools such as a screwdriver, a pair of pliers and a wedge, attempts to break into closed and locked building units.

Test duration: 15 minutes
Resistance time: 3 minutes

Doors in this class fulfil a low burglary resistance and are used in the following areas:

  • Average living area
  • Workshops
  • Trade

Resistance Class RC3

Experienced burglars are better equipped and try by means of a second screwdriver, various hand tools (small hammer, manual drill, etc.) as well as a crow bar, to gain access due to the stronger leverage. The drill equipment can be used to defeat vulnerable locks and security devices.

Test duration: 20 minutes
Resistance time: 5 minutes

Doors with the class RC3 are often used in areas with increased security requirements, such as:

  • Upscale living area
  • Business division
  • EDP systems
  • Banks

Resistance Class RC4

The experienced perpetrator additionally uses sawing and striking tools. This class is used when there are high security requirements.

Test duration: 30 minutes
Resistance time: 10 minutes

Doors in this class are used in the following areas:

  • Army
  • Banks
  • Data centres

Resistance Class RC5

The experienced perpetrator additionally uses power tools such as a drill, jigsaw or reciprocating saw and angle grinder. This class is used for higher security requirements.

Test duration: 35 minutes
Resistance time: 15 minutes

Doors in this class are used in the following areas:

  • Army
  • Banks
  • Data centres

Resistance Class RC6

The experienced perpetrator additionally uses powerful power tools, such as a drill, jigsaw or reciprocating saw and angle grinder. This class is used for the highest security requirements.

Test duration: 40 minutes
Resistance time: 20 minutes

Doors in this class are used in the following areas:

  • Army
  • Banks
  • Data centres
