What does a PASS result mean?

A PASS result means the validation step's deterministic threshold comparison was satisfied. It does not constitute laboratory certification or code compliance.

HOW THIS VERIFICATION WORKS

Step 1: Combined infiltration-diffusion moisture load summation — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
Step 2: RH setpoint optimization under probabilistic reliability constraint — engineering workflow step. Follow the documented method for manual execution.

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.

Step 1: Combined infiltration-diffusion moisture load summation

Formula(infiltration_load)+(diffusion_load)

Step 2: RH setpoint optimization under probabilistic reliability constraint

Manual Workflow

Perform iterative binary search over RH_sp ∈ [35, 45] in 0.5% steps; for each candidate, simulate closed-loop control (on/off or modulating) using C and RH_t to generate corrected RH_t_corrected; compute time-weighted average RH_avg = Σ(RH_t_corrected × duration_t) / 8760; accept smallest RH_sp such that RH_avg ≤ (RH_crit − δ) AND max(RH_t_corrected) ≤ RH_crit + 1.0% (transient overshoot allowance).

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 Bridge Cable Dehumidification Unit engineering verification is needed for project-specific conditions.
For calculation of Combined infiltration-diffusion moisture load summation (Step 1).
For calculation of RH setpoint optimization under probabilistic reliability 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.
