## Scope of this source

Public scope overview only; no complete color or placement specification was accessed.

The publisher overview describes identification of fluids in aboveground piping and excludes electrical conduits. It displays A13.1-2026 at the September 12, 2026 review. The overview does not supply the full color, size or placement requirements; project applicability requires the adopted text.

Rackstamp provides editorial field guidance. IDs, cases, and worksheet entries are fictional examples unless identified otherwise. Distinguish local conventions from adopted standards. Source notes describe the evidence scope; a linked overview is not the full standard or a project approval.
