NOTE:
1. The above data relate to machine moulded standard bricks only
2. Size tolerance +/- 1.5% or +/- 2 mm whichever is greater.
3. The AP and CCS values are arithmeric mean of five individual results.
4. PCE values of bricks above 36 orton cone and bulk density of all types are indicative only.
5. The above are average test data subject to reasonable variations.
