The resistance level depends on the tile type. Ordinary people can identify the resistance level of the tile using the rating. So you cannot just buy an anti-slip tile, you must know the rating level to get the right non slippery tile for your need.
There is no particular testing method for slip resistance like abrasion resistance. The testing procedure for determining the non slippery tiles differ between each country and they follow different grading levels.
In this article let us discuss the different types of slip resistance tests conducted on floor tiles.
Different Types Of Test For Finding The Best Non Slippery Tiles:
The two common tests done for finding the slip resistance of the tiles are a ramp test and a pendulum test. Some of the other tests are the tortuous tests, sled tests, and micro-roughness tests.
The pendulum test:
The pendulum test is also known as the coefficient of friction test. It is used to test the best non slippery tiles. Most manufacturers perform both pendulum tests and ramp tests.
The pivoted arm released during the test will contact the floor surface at its bottom arc. The interface used in this method is the shod sheel and it is mostly made up of rubber.
The rating for the floor is rewarded based on the extent to which the arm slows down because of the friction. This test type is called a pendulum test or PTV.
If the arm slows down fully then the floor has more slip resistance. The test can be done both on the dry floor and on the wet floor. The output of this result will be similar to the coefficient of friction.
The ramp test:
The common test performed for finding the slip resistance of the floor is the ramp test. Most countries use this method for finding the slip resistance.
Construction industry and architects use this method for finding the slip resistance. In this method, the subject attached to the ramp is made to walk on the tile surface wearing safety shoes.
The tile surface is covered with oil. The ramp is adjusted until the subject misses the balance. The angle of ramp height is noted in which the subject misses the balance.
If the angle is steep then the tile has more slip resistance. Based on the angle the tile is rewarded with an R rating. The rating level is between 9 and 13.
If the R rating is high for the tile or floor then it has high slip resistance. If the R rating is low for the tile then the floor or tile has low slip resistance.
The ramp test must be carried out only in the laboratory so you need the help of a lab technician and professional expert. The ramp test provides a consistent result.
This test is very expensive when compared with other slip resistance types. In this test instead of oil, you can also use soap water. The test conducted using soap water and barefoot is called a barefoot ramp test.
