HOW THIS VERIFICATION WORKS

Step 1: Apply Western Electric Zone Rules to I-MR chart points — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
Step 2: Solve for minimum n satisfying P-chart control limit width constraint — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.

This tool coordinates 0 validation steps and 2 calculation steps. The overall engineering decision uses ALL_REQUIRED_VALIDATION_PASS aggregation: only validation steps contribute to the pass/fail outcome; calculation steps produce data only.

METHODS & EQUATIONS

All formulas are resolved from canonical runtime definitions and executed deterministically by the client-side engine.

UNDERSTANDING THE RESULTS

PASS: A proven validation criterion passed. The engineering input satisfies the deterministic threshold.
FAIL: A proven validation criterion failed. The engineering input does not satisfy the deterministic threshold.
CALCULATED: A deterministic calculation completed, but no acceptance criterion exists for this step. CALCULATED does NOT mean PASS.
RESULT NOT VALID: Runtime executed but engineering validity requirements were not met.
INCOMPLETE: Required inputs or workflow steps are incomplete.

The overall decision reflects only validation steps. Calculation steps produce numerical results without pass/fail claims.

WHEN TO USE THIS TOOL

When deterministic Battery Formation System engineering verification is needed for project-specific conditions.
For calculation of Apply Western Electric Zone Rules to I-MR chart points (Step 1).
For calculation of Solve for minimum n satisfying P-chart control limit width constraint (Step 2).
For deterministic pre-checks before formal engineering review or submission.

When NOT to use this tool: This tool does not replace laboratory testing, formal engineering analysis by a licensed professional, or code-compliance certification. It performs deterministic threshold comparison and calculation only.
