Specifying Products under BS EN 124

The BS EN 124 standard serves as a general guide for determining the stability of products, and it outlines the parameters for different classes of products in terms of static load tests. However, it doesn't offer much specific information about the dynamic loads that various traffic conditions on modern road systems can impose.
