SCOPE & LIMITATIONS
HOW THIS VERIFICATION WORKS
- Step 1: Compute dQ/dV via central finite difference and locate dominant peak in specified voltage window — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
- Step 2: Identify CC segments and test for sub-zero voltage events within them — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
- Step 3: Compute capacity attainment ratio and evaluate against 95% threshold — 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 3 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: Unknown
CalculationN/AStep 2: Unknown
CalculationN/AStep 3: Unknown
CalculationN/AUNDERSTANDING 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
- During design development when Battery Cell Formation Machine fire-performance thresholds must be checked against project-specific conditions.
- When ceiling hanger dead-load estimates are needed from panel areal density and layout geometry.
- When installation air-gap clearance between panel rear surface and fixture must be verified.
- 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.
ENGINEERING FAQ
What does this verification tool check?
This tool performs three deterministic engineering checks: (1) fire-performance threshold validation comparing FSI and SDI against Class A limits, (2) dead-load calculation per ceiling hanger from panel areal density and layout geometry, and (3) installation air-gap calculation between panel rear surface and fixture front plane.
What does a PASS result mean?
A PASS result means the validation step's deterministic threshold comparison was satisfied. For this tool, it means FSI ≤ 25 and SDI ≤ 450. It does not constitute laboratory certification or code compliance.
Does this tool certify ASTM E84 compliance?
No. This tool performs deterministic threshold comparison only. It does not represent laboratory certification, ASTM testing, or complete standard compliance. Results should be validated against applicable codes and professional engineering judgment.
How is dead load per hanger calculated?
Dead load per hanger = (panel_grammage × 9.81) × (grid_spacing / 1000) × (hanger_spacing / 1000). The formula converts areal density to force and multiplies by the tributary area defined by the grid and hanger spacing.
Does the calculated dead load mean the ceiling grid is structurally acceptable?
No. The calculated value is the deterministic load estimate. Structural adequacy of the ceiling grid depends on manufacturer-rated capacity, installation conditions, and applicable codes that are outside the scope of this tool.
What does the calculated air gap represent?
The air gap is the net clearance between the panel's rear mounting surface and the nearest fixture front plane, computed as panel_mounting_depth minus fixture_protrusion. It indicates available space but does not verify code-minimum requirements.
What is not currently verified by this workflow?
Capabilities not currently verified include: structural adequacy of ceiling grid, code-minimum air-gap compliance, acoustic performance verification, and any requirements beyond the three implemented deterministic steps.
