We approach testing in a methodical, measurable, and repeatable way.  Unlike current industry guidance, which focuses on just two or three tests, our products undergo 12 rigorous mechanical and abuse assessments, as well as strict fire and acoustic checks. 



Our abuse testing is designed to simulate the physical abuse that our doorsets may be exposed to in a Mental Health environment.  Testing each part of the doorset and covering a range of attacks such as body impact and HNB mallet, they ensure that our doorsets can withstand extreme abuse, alerting staff of any disruptive behaviour before any serious damage can be caused. 


Slam shut test (DD 171)

Simulating the sustained abuse that a doorset is be exposed to in a Mental Health environment. It tests the durability of the doorstop and the frame's connection to the structural opening.


Body impact test (DD 171)

Simulating the repeated impact of a body slamming against the door and testing the damage to the doorstop, frame, hinge and fixings.

En-suite door


En-suite door: Abuse testing

Designed to withstand extreme abuse, the pivots are tested beyond the levels set by current industry guidance.


En-suite door: Trying to remove nibs

We bond the nibs to the door leaf, making them almost impossible to remove (we can't do it).


Vision panel attack test

Can a vision panel sustain a continued assault without becoming a risk to the service user? Sureview can.


Physical attack test

Simulating a sustained attack on the door and hinge to ensure that no prospect of self-harm are exposed.


Leg jamb test

This test focuses on the emergency release doorstop (Swiftstop), simulating a service user trying to barricade the door using their body strength.


En-suite: Weaponisation

The soft, lightweight en-suite leaves fold over when held – making them hard to swing and minimising the risk of weaponisation.


Seclusion door: Abuse testing

Built to withstand extreme abuse, our seclusion room door was hit more than 100 times with a paving maul in the same location. 




Fire rating test

We design safety into our products. The result? Fire-safe doors rated up to FD30 and FD60. This tests the complete doorset package - from the lockset and vision panel to the hinge and door closer.


En-suite fire test

Designing safety into our products, we fire tested our En-suite door for BS EN 597 and BS EN 1021 match flame equivalent. The En-suite door passed both fire tests.


Downward deformation test

Measuring how much the door drops when a large force is applied downwards through the door handle. This tests whether the door hinge is damaged to the extent that the door can no longer contain a fire compartment.

Ligature testing



En-suite anti-ligature testing 

Removing all known ligature points, the leaves of the en-suite door detach under abnormal load (6-8kg) and the pivots are designed to resist ligature attachment. 

Anti-ligature handle testing 

We use the TS001 specification to independently test all of our handles – and they all pass at the highest levels in their respective categories.
