Burglar Resistance Classification According to EN 1627:2012
EN 1627:2012 is the European standard that defines the classification system for burglar resistance properties of doors, windows, curtain walling, grilles, and shutters. The standard establishes six resistance classes (RC1 to RC6), each representing different levels of security.
Resistance Classes Overview
RC1 (Resistance Class 1)
Basic protection against:
- Opportunistic attempts using physical force
- Vandalism
- Simple levering attempts
RC2 (Resistance Class 2)
Protection against:
- Occasional burglar using simple tools
- Basic power tools
- Extended levering attempts
RC3 (Resistance Class 3)
Enhanced protection against:
- Experienced burglar using crowbars
- Multiple screwdrivers
- Hand tools
RC4 (Resistance Class 4)
High protection against:
- Experienced burglar using heavy duty tools
- Battery-powered tools
- Saws and drilling equipment
RC5 (Resistance Class 5)
Very high protection against:
- Professional burglar using power tools
- Angle grinders
- Advanced drilling equipment
RC6 (Resistance Class 6)
Maximum protection against:
- Professional burglar using powerful electric tools
- Heavy duty cutting equipment
- Advanced powered drilling tools
Testing Requirements
Each resistance class is tested against:
- Static loading
- Dynamic loading
- Manual attack testing
- Specific tool sets defined for each class
- Defined time periods of resistance
Components Tested
Testing includes assessment of:
- Door leaf or window sash
- Frame construction
- Glazing systems (if present)
- Lock mechanisms
- Security hardware
- Installation methods
Application Guidelines
Recommended applications by class:
- RC1-RC2: Residential properties with standard security needs
- RC3: Commercial properties and high-end residential
- RC4: Banks, jewelers, and high-security facilities
- RC5-RC6: Government facilities, high-value storage, critical infrastructure
Certification Requirements
- Testing by accredited laboratories
- Regular audit testing
- Documentation of compliance
- Proper labeling and marking
- Installation by certified professionals
Important Considerations:
- Classification must match security requirements
- Higher classes require increased maintenance
- Insurance requirements may dictate minimum class
- Local regulations may specify minimum standards
