Taber abrasion wear testing of stone floors is an important aspect of evaluating the suitability of a proposed floor surface.
Safe Environments can assist in assessing the wear resistance of a particular stone floor by using the Taber Abraser to conduct accelerated wear tests. These tests will then be able to establish whether the floor is susceptible to wearing away or suitable for its intended purpose.
Abrasion wear testing is important because the durability and wearability of a stone floor surface should be an essential part of any decision concerning which surface will best stand the test of time.
An example of a stone surface that has not stood the test of time are stairs whose centre has become dipped. This is the result of wear and erosion over time from many people scuffing their surface.
An abrasion index greater than 25 is ideal for stone floors that need a high resistance to abrasion. Granite is a hard stone and it can generally achieve an abrasion index larger than 25. Limestone, sandstone and marble are classified as soft stones and as such may need more rigorous abrasion wear testing.
The Taber abrasion wear testing technology is also suitable for testing polymer floor coatings to assess the wear resistance effect of different polymer compositions, fillers and plasticisers.
During the test, the abrasion index is calculated by the volume loss of the material. The sample is attached to the base of the Taber Abraser which is then rotated against a set of abrasive calibrade wheels that apply a specific force to the sample. By working out the material’s density, the volume loss is then calculated by the change in mass due to the Taber abrasion process.
