Rationale

In C67, replace Figure 7 Out-of-Square Measurements with a version that could be used for assessing thin brick units as well as other units. The current figure uses the terminology “upper bed surface” which excludes the application of the test method to thin brick even though the method is appropriate for evaluating the out-of-square measurement for the face to be exposed in a thin brick unit. This proposal substitutes a new figure with generic language that is applicable to a wider range of units.
