Testing Facilities

Achieving the balance between design and practicality

Dellner Glass Solutions are often asked to develop new products that push the boundaries of design capability but also must adhere to strict security and safety standards.

To be able to achieve the delicate balance of design vs. practicality, we have considerable onsite testing facilities at both of our manufacturing sites to test and prove any new product designs. Drop and soft body impact testing to GM/RT2100, including small missile testing at Consett. The Consett facility also houses a large canon to allow onsite testing to EN15152.

The cannon room includes environmental testing and can be refrigerated to replicate arctic conditions and heated to replicate desert conditions.

For our ballistic test requirements (EN1063), we have relationships with accredited partners to undertake all of assurance works for any new glass constructions.

At Tamworth, we have a bespoke water test facility which allows all of our window and door designs to be fully tested, in line with industry and customer requirements to guarantee performance in all weathers.

For project-based work, particularly in the rail and transport markets, our clients are invited to witness the tests in action, to get a feel of how their design looks, but also to see how it performs in conditions.

Bullet Resitance - Slow Motion

Our bullet resistant glass is some of the strongest and lighest on the market and we owe that to hours of dedication from our technical team who always strive to develop our capability in glass. 

Our slow motion video is filmed from the front and then the reverse to see how the impact is absorbed by the glass. 

GM/RT2100 Impact Testing

Our test fixtures allow us to undertake small missile testing for our rail bodyside windows, according to GM/RT2100 Appendix C, after test samples are conditioned for hot and cold environments, our equipment fires a 0.25Kg projectile at a speed of 100km/hr. The test glass is checked and fragments weighed to prove compliance to the test parameters.

Alongside the small missile test, we also have onsite test fixtures for large missile and soft body impacts, according to GM/RT2100 Appendix D. We take our window system and install this into a fixture representative of the vehicle installed condition and then subject it to 3 sequential tests, a 5Kg steel ball to the outside face, followed by a 50Kg pendulum impactor to the inside and finally a static point load of 81Kg to the inside face – these tests replicating a vehicle crash scenario.

These on site fixtures have allowed Dellner Glass Solutions to create many different glazing systems for the UK rail sector, complying with the very latest safety standards.

Cannon Testing

Our cannon room is usually used for rail projects to ensure our windscreens conform to BS EN 15152. A 1kg domed aluminium impactor is fired out of a high pressure air cannon at a speed determined by the operating speed of the train (train max speed plus 160Km/hr).

The test is conducted in ambient, extreme heat and extreme cool conditions in each corner of the windscreen and the centre and is deemed successful projectile has not penetrated the windscreen and glass fragments have not been released inside the driver's cab. Dellner Glass Solutions has won significant contracts with global train builders due to it's capability of developing new technologies, incorporate sleek designs and test all on site.
