Definition
control limit established from statistically sufficient process data and used for routine monitoring and evaluation of stable long-term process performance
Explanatory Notes
A long-term control limit is established after sufficient manufacturing data have been collected to characterize normal process variability with statistical confidence. It serves as the boundary for routine monitoring, trend evaluation, and process capability assessment, replacing provisional control limits once stable operation is demonstrated. Long-term control limits are periodically reviewed and re-established as part of lifecycle maintenance.
Examples
- After one year of commercial production, temperature control limits of 36–38 °C are established as long-term control limits based on statistical analysis of 40 commercial manufacturing batches from a stable process
Synonyms
- long-term control limit

Primitive Class
This class is declared primitive and it does not have necessary and sufficient condiftions defined.
Primitive Rationale
This term is expected to remain primitive as it is not expected that a formalization of sufficient process information will be available that can fit all use cases.
