  • Loading Specification
Jonite has certified test reports for load tests set out in EN 124 and EN 1433 standards.
Static Loads refers to load applied vertically to the grating with no other movement, such as load from a stationary vehicle. Wheel-loads refer to the weight of the vehicle and its typical load depending on the type of the wheels. Pneumatic tyres spread the load like the test-block in the illustration and solid tyres post a greater point load, which is only recommended for Class E600 and F900. Vehicle movement, speed, braking and traffic frequency are the consolidated consideration of dynamic loads.
