Definitions:

Lower Limit

The lowest value in a set of data, or the minimum value that a certain variable, function, or sequence can assume.

Specification Limits

Pre-determined bounds that define the acceptable range of variation for a product's characteristics or a process's outputs.

Standard Deviation

A measure of the amount of variation or dispersion of a set of values, indicating how spread out the values are from the average.

Sigma Control Limits

Statistical boundaries set in process control that indicate whether a process is in a state of control or needs adjustment, based on the standard deviation (σ) of the process data.
