This standard specifies the dimensions, quality requirements, and testing methods for hand-made burnt clay flat terracing tiles used for roofing and terrace finishing. It details limits for water absorption, flexural breaking load, and efflorescence to ensure durability.

Practical Notes
Hand-made tiles naturally have higher dimensional variations compared to machine-made tiles; plan for slightly wider and more flexible mortar joints.
Tiles must be thoroughly soaked in clean water before laying to prevent them from absorbing moisture from the bedding mortar.
Always test a sample batch for efflorescence before bulk installation to prevent unsightly white patches on the finished terrace.
