| 8.The data given in this Technical Information. Sheet have been determined as average values on test specimen of
machine-pressed standard bricks or products of similar size to standard bricks.They may not be applied without
reservation to other sizes, since they may vary within reasonable limits and should not therefore be regarded as definite
values of a property. The limiting temperature of application depends on the type of service and the type of shape. |
