5 Test methods
5.1 General
Where other test methods are used for factory production control (FPC) a satisfactory statistical correlation
with the test methods specified in this document shall be demonstrated.
5.2 Hanging length and squareness of regular front edge tiles
5.2.1 Principle
Tiles are hung from steel battens and measured to establish hanging length and also the squareness of
regular front edge tiles.

5.2.3 Procedure
5.2.3.1 Tiles with nominally constant hanging length
Hang the tile at an angle of 20° to 70° on a steel batten (see Figure 1a)). After physically removing any burrs
and/or other irregularities, measure from the top face of the batten to the lower front edge of the tile at the
sides (see Figure 1b)), excluding the interlocking sections in the case of tiles with sidelocks.

5.2.3.2 Tiles with regularly varying hanging length
Hang the tile at an angle of 20° to 70° on a steel batten (see Figure 1a)). After physically removing any burrs
and/or other irregularities, measure from the top face of the batten to the lowest point of the tile (see Figure
1c)).
