The current standard classifies brick according to their resistance to damage by freezing when saturated but gives little indication of other factors that affect not only the likelihood of the brick exceeding the 24-hr cold water absorption, but also the overall performance of the brick. The durability of even the most durable brick is deleteriously affected by detailing or installations that increase the potential for brick to absorb water exceeding the 24-hr absorption. This proposed change serves to alert readers that there are factors outside the realm of the properties of the unit itself, or whether the brick is installed in a position that creates a horizontal or sloped surface, that affect performance and durability.
