BS EN 425: “Resilient floor coverings – Determination of the effect of rolling loads” is a European standard that provides the method for assessing how resilient floor coverings (such as vinyl, linoleum, rubber, and other similar materials) react to rolling loads. These types of loads simulate the impact of heavy furniture, equipment, or vehicles that roll across the surface of the flooring.
Here are key details about BS EN 425:
Purpose
The standard is designed to measure the resistance of resilient floor coverings to permanent deformation when subjected to rolling loads. This is important for ensuring that the flooring maintains its aesthetic and functional properties over time in environments where heavy, rolling equipment is used, such as in hospitals, offices, airports, or industrial settings.
Testing Method
The test involves using a specified rolling load (often a steel wheel or similar device) applied to the surface of the flooring. The key measurements taken include:
- Indentation: The depth of permanent deformation caused by the rolling load.
- Durability: The ability of the floor covering to withstand repeated rolling loads over time without significant damage.
- Recovery: How well the flooring recovers from deformation after the load is removed.
Test Conditions
- The flooring is typically tested under controlled conditions, with defined temperature and humidity levels.
- The rolling load is applied a set number of times to simulate realistic wear and tear.
Results
The outcome of the test is a measurement of the floor covering’s performance under rolling loads. Floor coverings that perform well in these tests are less likely to develop permanent marks or damage from items like office chairs, trolleys, or other mobile equipment.
Relevance
This standard is particularly important in environments where heavy or rolling equipment is frequently moved over the floor. It helps manufacturers and users select the most appropriate resilient floor coverings based on their durability and performance under such conditions.
This standard is widely recognized in Europe and forms part of the broader set of standards that ensure the quality and performance of flooring materials. system.
