Design/Performance requirements:

Independent Empirical Test Minimum Performance Requirements:
The brick slip system must achieve the following minimum performance values, verified by testing, carried out by a UKAS accredited test facility. Performance compliance must be demonstrated by the submission of test reports.

The minimum test panel size must be 3M (H) x 3.6M (W) with the backing wall construction such that deflections within the backing wall are equal to or exceed those that will be exhibited by the actual project construction.

The test panel must incorporate brick slips that represent the full brick slip height tolerance range in which bricks compliant with BS EN 771 might be supplied. Testing must demonstrate that the brick slip system achieves the minimum required performance values with brick slips that range in height from 58mm to 70mm.

Brick Slip Pull Out Testing - Brick Slips in their Un-Mortared (Temporary) State - Wind Resistance - Safety:
Brick slips, of the type intended to be supplied, ranging in height from 58mm to 70mm must resist a pull-out load of 100N per brick. Each brick slip must resist the following sequence of pull-out loads applied perpendicular to the plane of the brickwork without detachment.

3 No. x 85N applied for a 30 second duration with a 30 second recovery period
1 No. x 100N applied for a 30 second duration with a 60 second recovery period
Displacements must be measured after each recovery period.
Required Result: = Pass
