Dura Slab BS EN124 Approved

Dura Slab is BS EN 124 approved. This European standard applies to gully tops and manhole tops for vehicular and pedestrian areas. In order to reach this approval a Dura Slab panel of 74mm thickness and 1280mm span was subjected to a load equivalent to two thirds of the Class B test load, 83.3kN, and then reduced to zero.

This load cycle was repeated four further times and then the permanent set measured which must not exceed 1/100th of the span. The panel was then further loaded to the Class B test load, 125kN, which was maintained for 30 seconds. Following the final load cycle of the BS EN124 test, loading was continued to cause failure. The panel finally failed at a load of 152kN. The panel was found to meet the load requirements for a Class B 125 cover.
