At the request of several manufacturers of spacer grid systems, the MCRMA supervised a series of structural tests carried out at a well-known testing laboratory. The tests were designed to establish the structural performance of the components and the loads were greater than would be found in site conditions.

The description of the tests is as follows:

• 1 Bracket/ferrule to zed/rail attachment.
  
• 2a Point load to centre span rail/zed.
  
• 2b Point load to bracket/ferrule to zed/rail attachment.
  
• 3 Down slope across the rail/zed load.
  
• 4 Along the rail/zed sway load.
