No More Props was tested by Ceram Building Technology of Stoke-on-Trent. The temporary lintel underwent a Uniformly Distributed Load (UDL) Test and an Ultimate Load Test. The first tests the unit to failure with no support of a wall structure, and the second tests the load sustained within a brick wall.
Both tests showed the factor of safety to be far in excess of the BS Standard for lintels.
The results of the Uniformly Distributed Load Test are shown, for the 3 sizes of unit, in the table on the Load Bearing Capability page. The results of the Ultimate Load Test are shown in the table beneath. The load bearing within a wall is far greater, due to the load being partially distributed throughout the wall structure. At 73.43 kN, the wall failed, but there was minimal deflection of the No More Props temporary lintel.
