Let’s talk Coefficient of Friction!


A conversation about the Coefficient of Friction (CoF) may not conjure the most thrilling of discussions, but there’s no denying its integral role when we talk about standards and international requirements. Join us as we delve into the riveting world of CoF!

CoF, a fundamental factor that impacts safety in various industries, is not a new concept. It has been at the forefront of product design and safety measures, yet it remains shrouded in mystery for many. We’ve alluded to the prominence of Pendulum, a non-slip standard in our previous blogs. Here, we plan to explore further its nuances, its evolution, and other essential CoF standards in the global arena.

The Pendulum test, a dynamic method of measurement, is commonly juxtaposed with static tests. We all remember physics class, don’t we? Static measures the force needed to coax a stationary object into motion across the surface, whilst dynamic tests, like Pendulum, gauge the amount of effort required to cease the movement of an object. ISO7176 serves as a prime example of a static CoF test. The relevance of these two types of tests hinges on the fact that humans are mostly on the move when they slip, making dynamic CoF tests more representative of real-life scenarios.

Unravelling a bit of history here, the Pendulum test is a proud British creation, credited to the Road Research Laboratory. This significant method initially bore the certification of BS7976. However, as the world became more connected, the need for an internationally recognised standard grew apparent. Consequently, the EN 13036-4 replaced BS7976, providing the same technical approvals and aiding in seamless cross-border operations.

Yet, the world of CoF doesn’t revolve solely around EN 13036-4. There’s a whole constellation of other standards, each contributing to enhancing safety and compliance in various industries. To name a few, there are the German DIN51130, DIN51097, and many more. These standards, while distinct in their methodologies and applications, all share the common goal of preventing accidents caused by slipping.

Now, you might ask, why does all of this matter? The answer is straightforward: safety. In industries such as construction, transportation, and manufacturing, where the safety of individuals is paramount, CoF plays a significant role in ensuring that surfaces are safe for movement and use. Consequently, understanding and adhering to these CoF standards is not just about regulatory compliance, but also about creating safer environments for everyone.
