A Laboratory Test
The test was carried out at the Pipe Centre, Danish Technological Institute Taastup in Denmark. The rat penetration test was conducted according to the Danish test standard for rats in sewer systems. Adjustments to the test strategy and scope was made to reflect the case-setting of rats trying to penetrate underneath a door blade.
As seen on the pictures above the Raxit Door Seal was mounted on a mock-up double door (in a closed quadrangular test box). There was no threshold installed underneath the double door. The reason for not installing a threshold underneath the doors, was to reflect a real-life scenario where pallet-jacks, fork-lifts, etc. can drive through. From the bottom of the door to surface there was left a 50 mm gap, enough space for the rats to crawl under.
The first seven days of the test was conducted without the Raxit Door Seal installed, for the rats to get familiar with the box and where it could feed. The second part, and last seven days, of the test was conducted with the Raxit Door Seal installed, blocking the way so the rats could not reach their food.
The Raxit Door Seal successfully passed the test as the rats was unable to penetrate through the Raxit Door Seal, even after heavy gnaw marks was observed.
In addition to the rat penetration tests we have also conducted; durability, climate and water barrier tests successfully at the Danish Technological Institute.
