For the benefit of Risk Xtra’s readers, Craig Birch outlines what the new Grade 5 for BS 8607 (focused on Mechanically Operated Push-Button Locksets) includes, why it has been introduced and the benefits that it can help deliver for host organisations.
At present, mechanically operated push-button locksets are not typically security products, but rather access control ones. For example, think about the last time you went to your local doctor’s surgery. No doubt there will have been a lock on the door behind the receptionist, protecting the sensitive information held on file – a demand that has become only more critical with the introduction of the EU’s General Data Protection Regulation (GDPR).
However, the truth is that the lock protecting the restricted area in question is probably little more than a tubular latch. Essentially, it’s not a security device, but rather one that’s used for convenience to simply meet the access control needs of a specific site.
However, BS 8607 – the British Standard for mechanically operated push-button locksets – offers a series of grades that these locks can meet for strength and robustness. Introduced only recently, Grade 5 is the newest and most stringent level for delivering assured security and access control. What does it offer that Grade 4 doesn’t?
BS 8607 in detail
The British Standards Institution (BSI) states that BS 8607:2014 specifies the requirements and test methods for durability, strength and function for mechanically operated push-button locksets and their locking plates for use on doors, windows and entrance doors in buildings.
Both Grade 4 and Grade 5 of BS 8607 stipulate that products meeting these standards must be suitable for ‘applications where security, abuse and usage levels are expected to be equivalent to BS 3621’, which relates to thief-resistant locks, but if the security, abuse and usage levels are the same, what then is the difference between the two grades?
Put simply, those rated as Grade 4 can only achieve this standard with the help of an integral additional locking unit. So, with a Grade 4 product, end users must lock and unlock the solution from the inside with a key and then operate the push-button from the outside to unlock a door.
In contrast, a mechanically operated push-button lockset that meets Grade 5 standards provides a ‘one-stop’ security and access control solution; one that doesn’t require a separate locking unit. In short, with a Grade 5 product the latch and lock are integrated and tested together without the need for an additional key. The end result is a solution that offers keyless egress. This means that, when it shuts, a Grade 5 solution automatically locks. Then, should you need to exit a room, it’s simply a one handle operation to unlock the door.
While it’s intended that both Grade 4 and Grade 5 devices offer the same resistance to attack and it’s simply the way it’s locked that’s different, the fact that a user has to physically lock a door themselves with a Grade 4 product means the technology is reliant on key holders to secure the premises themselves.
Ultimately, users have to take responsibility and ownership for the security of a site. With a Grade 5 solution, though, security is assured as the door will lock automatically.
Why the need for Grade 5?
Essentially, Grade 5 has been introduced because it provides a BSI Kitemark approved certification. This means any mechanically operated push-button locksets advertised as meeting Grade 5 standards will be fully tested and inspected to this certification, offering complete peace of mind to end users, installers and specifiers alike.
As a result, there’s no question that a Grade 5 product will meet the security and access control needs that so many commercial environments demand. A Grade 4 product is reliant on an additional locking unit that meets BS 3621 being used too, whereas a Grade 5 solution delivers assured protection and access control in a single package.
Finally, the BSI Kitemark for a Grade 5 solution is an official stamp of approval for the quality of the service offered.
To date, it’s this combination of security and convenience that hasn’t yet been seen in mechanically operated push-button devices. Grade 5 of BS 8607 looks set to change that situation.
