What is it used for?
This test is used to test how well a release bond performs under loading.
How it’s done:
- A 150mm square of floorcovering is bonded to a plywood board, using a release adhesive, and four pressure points are applied to simulate table legs.
- The sample is kept under a 30kg weight for 7 days
What’s next?
After this period, the floorcovering is released from the plywood by hand.
The test assesses the effectiveness of the release bond across the whole area, by checking that the loading points haven’t caused the release bond to fail.
