Notes About Rule Evaluation

• Unity Real Time™ online rejects the entire row if any data within a run violates a SPC rule with a status of reject.
• Unity Real Time™ online excludes rejected data rows when evaluating rules between runs.

For example, a test is being evaluated using the 1-3s and 2-2s rules, both set to reject. If run four violates the 1-3s rule and run five violates the 1-2s rule, the second run is not rejected as violating the 2-2s rule.

Note: Excluding rejected data is based on the assumption the test system was evaluated in response to the rejection and the laboratory took corrective action. Unity Real Time™ online assumes subsequent data points reflect these actions.
