Ramp Test Values (DIN 51130)

Understanding Ramp Test Data

DIN Standard Ramp Testing (DIN 51130) is an alternative to Pendulum Testing and generally categorised as an 'off-site' activity because of the size and complexity of the equipment required to carry out the test. The Slip Resistance Values (RSV) are factory gate values (based on supplied tiles) and categorised using the Ramp Test (DIN 51130) method which is commonly used by European factories. In this method, a lubricated inclined platform is adjusted to a gradually increasing gradient, and the angle is measured at which a person walking on it slips.

We have deliberately not included the ramp test angles on this page as this information can be confused with the angle that a floor may be safely set to, which is incorrect. The shod test results are quoted as an R Rating value from R9 to R13, which relates to the ramp angle.

R Rating Value	Friction
R9	Minimal
R10	Normal
R11	Good
R12	Good
R13	Very high

See the Health and Safety Executives website for more information regarding the Ramp Test procedure. Ramp Test Certificate available on request.
