Rationale

The intent of this change is to clarify the footnote on Type FBS units to Table 4 Maximum Permissible Extent of Chippage From the Edges and Corners of Finished Face or Faces onto the Surface as follows: 1. to clearly indicate that only smooth extruded brick may be Type FBS brick categorized as Plain units, 2. to change “broken” to “altered”, and 3. to change “and” to “or” in two instances.
