# Data dictionary — UL 325 Commercial Door Compliance Ledger v1.1

Total rows across the seven CSV files: 164.
No reuse license has been assigned.

## Evidence marks

- **R — Source-reported:** checked in the cited public source at the stated locator or document section.
- **C — Compared/editorial synthesis:** derived from named cited records. It is not an agency, standards-body, or manufacturer finding.

## Missing-value rule

`n/a` means not applicable. A blank cell does not mean zero. Where a source is silent, the row says that the point is unknown or not established rather than filling the gap by inference.

## Scope and reuse notes

- The complete paid UL 325 standard was not available for full review. Public clause references appear only where a public issuer, agency, or authorized guidance document identifies them.
- A manufacturer statement applies only to the named brand, model family, configuration, and document edition.
- DASMA technical sheets are industry guidance and do not replace manufacturer instructions or applicable law.
- A listed product, an adopted code, an agency rule, a project specification, and an editorial recommendation are different evidence classes.
- The checklist supports records and safe observation; it does not authorize electrical, wiring, interlock, stored-energy, or fire-door work.
