Overview of slip resistance classes

Slip resistance classes R9 to R13 according to DIN 51130 are standardized classifications that evaluate the slip resistance of floor coverings, particularly in commercial and industrial environments. This classification helps to determine the safety of floor coverings with regard to the risk of slipping.

Overview of slip resistance classes - Here are the individual classes and their characteristics:

The determination of the slip resistance class according to DIN 51130 is carried out using a standardized test that evaluates the slip resistance of floor coverings. The test is performed in a controlled environment and includes the following steps:

The test setup for DIN 51130 simulates the risk of slipping on oily floors in work areas. A floor covering is attached to an inclined plane, coated with motor oil (200 ml per square meter), and walked upon by a person wearing standardized safety shoes. The angle of inclination of the plane is gradually increased until the person begins to slip. The achieved angle determines the slip resistance class (R9 to R13) of the floor covering.

Detailed procedure:

• Preparation of the floor covering: The floor covering to be tested is attached to an inclined plane.
• Contamination: The floor covering is covered with a defined amount (200 ml/m²) of motor oil to simulate an oily surface.
• Test person: A person wearing standardized safety shoes walks onto the oily floor covering.
• Increasing the angle of inclination: The angle of inclination of the inclined plane is increased step by step.
• Determining the slip angle: The angle at which the test person begins to slip in their shoes is measured.
• Slip resistance class: The measured angle is assigned to a slip resistance class (R9 to R13), where R9 represents the lowest and R13 the highest slip resistance.
  

Important points:

• Area of application:
  DIN 51130 is relevant for work areas where oils or fats can reach the floor, such as kitchens, workshops, or industrial halls.
• Standardized shoes:
  The test person uses standardized safety shoes to achieve comparable results.
• Inclined plane:
  The inclined plane is the central element of the test setup used to simulate the risk of slipping under varying angles of inclination.
• Slip resistance classes:
  The test results are classified into slip resistance classes (R9 to R13), which reflect the slip resistance of the floor covering.
