Service life
Years in service. The band runs from the shortest to the longest life the sources state, so it shows how much they disagree, not how long 80% of units last. The line is the median of the stated lives.
Basis
- 50 years · CNA e-Tool Estimated Useful Life Table, p14 · HUD CNA 3.6.1.1 “Building fire suppression sprinklers, standpipes” — U.S. Department of Housing and Urban Development (planning life)Same life for family and elderly properties. US multifamily housing. HUD gives sprinklers and standpipes one row.
- 25 years · General depreciation rates (IR265), July 2021, p43 · BDFO “Dry risers” — Inland Revenue (Te Tari Taake), New Zealand (accounting life)Printed page 43. A dry riser is a dry standpipe. BDFO Building fit-out (when in books separately from building cost). Printed DV 8%, SL 6%. Tax depreciation lives set by the Commissioner of Inland Revenue for New Zealand income tax, not engineering or asset-management lives; they are banded and often short (e.g. reticulation piping 25 years). The July 2021 edition was the newest PDF reachable; the online Depreciation Rate Finder may hold later determinations.

Municipal lives for fire protection (D40)
17 municipalities in British Columbia and Ontario state a life for fire protection as a whole, in 10 distinct tables: 15–50 years, median 20. These come from capital asset policies: accounting lives, used for amortization. They describe the system rather than this component, and none is a measured life.
Years. Each dot is one stated life and each bar a stated range; equal values stack. The dashed line is the median. Policies that copy the same table count once.
