What are the standard thicknesses for chequered tiles?

The standard specifies thicknesses of 20 mm, 25 mm, and 30 mm (Table 1).

What is the maximum allowed water absorption for these tiles?

The average water absorption by mass must not exceed 10% (Clause 7.3).

How is the strength of the tile specified and tested?

Strength is specified as 'Wet Transverse Strength' (Modulus of Rupture). For a 25 mm thick tile, the average strength must be at least 2.5 MPa (Table 2).

What is the wear resistance requirement for these tiles?

The average wear in the abrasion test should not exceed 2.0 mm (Table 2).

Practical Notes

Ensure the wearing layer (top layer with color and chequers) has a minimum thickness of 6 mm as per the standard for durability.

During installation, a proper base course and mortar bedding are crucial to prevent cracking under service loads.

Verify the depth of chequers on-site; too shallow a pattern offers poor slip resistance, while too deep a pattern can be a tripping hazard and collect debris.
