31 Mar What is BS3621?
BS3621 is a standard that provides a minimum level of protection for locks and key-operated security devices. The standard was introduced by the British Standards Institution (BSI) to set guidelines for security measures against forced entry, picking, drilling, and manipulation.
Locks that meet the BS3621 standard are approved and tested by independent third-party testing organizations for their quality and durability. These locks are widely used in residential and commercial properties, and insurance companies often require them to be installed to reduce the risk of theft or break-ins.
One key feature of BS3621 locks is the presence of a deadbolt that extends at least 20mm into the door frame when it’s locked. This helps to prevent forced entry through the door by means of a crowbar or similar tools. The lock also requires a key to operate from both sides of the door, which provides an additional layer of security.
Another important aspect of the BS3621 standard is the use of hardened steel for the lock mechanism and keys. This makes the lock more resistant to drilling, sawing, and other forms of physical attack.
In addition, BS3621 locks are designed to be compatible with other security devices such as alarms and CCTV systems, making them a key component of a comprehensive security system.
It is important to note that the BS3621 standard applies only to key-operated security devices and does not cover electronic or digital locks. However, the BSI has developed similar standards for these types of locks to provide a similar level of protection.
Overall, the BS3621 standard provides an essential benchmark for lock quality and security, and homeowners and businesses should consider using locks that meet this standard to enhance their protection against burglary and theft.
