SPC Rules Precedence When Showing Rule Violations

For the purpose of rules precedence, SPC rules are divided into the groups shown in the columns in the table below. Rules are arranged in decreasing order of severity within each group. If a data point violates more than one rule in a group, Unity Real Time™ online shows only the most severe rule violation in the Rules column on the Data Entry dialog box and on intralaboratory reports and charts. Unity Real Time™ online evaluates the data against all active rules; however, rules are sometimes truncated in the Rules column on the Data Entry dialog box to simplify viewing.
