Pendulum Dynamic Coefficient of Friction (DCOF) Test Device (Tribometer) for assessing the slip resistance of floors and roads using published test methods such as ASTM E303-22, BS EN 16165:2021, AS 4586, AS 4663, and others. The pendulum dynamic skid resistance test device (sometimes called the British Pendulum Tester) has been in use for over 50 years and has a published, peer-reviewed test method in at least 50 nations around the world. This means it has been proven again and again in dozens of countries and dozens of international studies to have precision, repeatability and reproducibility. The pendulum tester is easily the most widely-trusted slip resistance test device in the world today for assessing real-world slip risk of flooring both in the lab and in the field.
