Need to Install or Upgrade/Replace Locks? - No Problem

Check your home contents insurance policy - does it state that you must have BS 3621 (British Standard) locks fitted to all final exit doors, or locks with at least 5 levers, and window locks (with removeable keys) on all windows? If the small print states you must have 'approved locks', do you know exactly what they mean? Call them and find out - chances are that you are not insured if you do not have the level of security they require.

 

So what does BS3621 (British Standard) actually mean?

British Standards Explained: BS 3621:2007 + A2: 2012

We are all familiar with BS lever operated Mortice locks but what does it take for them to pass the British Standard certification? Below is a quick guide to the most common requirements:


1.    Differs

b.    Key markings should be used only once and shouldn’t disclose the combination of the key.

2.  Lock case

b.    Lock cases must be able to withstand a lateral force of 10,000N for a minimum of one minute.

c.    Hook or claw bolts must be able to withstand a pull force of at least 6,000N.

3.    Deadbolt
a.    The deadbolt must throw at least 20mm.

b.    The deadbolt is tested with a force of 15N to the end of the deadbolt to ensure that it cannot be pushed back.

c.    The deadbolt must be able to withstand attack by cutting or drilling and is subjected to 5 minutes of drilling.

d.    The deadbolt must be able to withstand a force of 6,000N for one minute in the direction that the bolt moves to unlock.

 5.    Strikes
Staples and strikes are tested by applying a force of 10,000N.

 6.    GVA
