## Key Technical Definitions

### Burglar Resistance (EN 1627)

RC (Resistance Class) — burglar resistance classification under European Standard EN 1627:2021:

- **RC2**: Entry-level certified burglar resistance. Resists simple tools (chisel, screwdriver, wedge, hacksaw). Suitable for residential and light commercial premises.
- **RC3**: Resists heavy-duty manual tools (crowbar, locksmith hammer, hand drill). Common for shops, pharmacies, medium-risk commercial premises.
- **RC4**: Resists power tools (cordless drill, angle grinder ≤400W, reciprocating saw). Standard for banks, government buildings, data centres, embassies.
- **RC5**: Resists high-power tools (650W electric drill, angle grinder, jigsaw). For bank vaults, military facilities, prisons, panic rooms.
- **RC6**: Highest class. Resists 1050W drill, 2300W angle grinder with 230mm cutting disc. For central bank vaults, military command centres.

### Bullet Resistance (EN 1522 / EN 1523)

FB (Firearms Bullet) — ballistic resistance classification under European Standard EN 1522:

- **FB4**: Resists .44 Magnum (SCP) at 440 m/s. For banks, cash-handling facilities, jewellers.
- **FB5**: Resists 5.56×45 mm NATO at 950 m/s. For police stations, embassies, VIP facilities.
- **FB6**: Resists 7.62×51 mm NATO at 830 m/s. For military facilities, high-security government installations.
- **FB7**: Highest class. Resists high-energy rifle rounds. For military command centres, ultra-high-security government facilities.

### Fire & Smoke Resistance (EN 16034 / EN 13501-2)

EI — fire resistance classification:

- **EI**: E = Integrity (prevents flames/gases passing through). I = Insulation (limits heat transfer to unexposed side to <140°C average).
- **EI30**: 30-minute fire resistance. Common for residential escape routes, stairwells.
- **EI60**: 60-minute fire resistance. For higher-risk commercial premises, server rooms, plant rooms.
- **EI120**: 120-minute fire resistance. For industrial facilities and high fire-load areas.

TDS supplies security doors combining RC + EI (e.g. RC4 + EI60) — both burglar-resistant and fire-rated simultaneously.

### Explosion / Air-Blast Resistance (EN 13123)

EXR — explosion resistance classification:

- **EXR1–EXR5**: Resistance to air-blast overpressure from gas explosions or detonations. Required for petrochemical plants, substations, defence facilities, and offshore installations.
