Enclosure

Net volume V (m³) Overall height H₀ (m) Height of highest hazard H (m) top of the protected equipment

Enclosure shape

Extinguishing system

Design standard from the O&M Installed or last redesigned

Agent and quantity on the cylinders match the O&M?

Agent Design concentration (%) from the system design / O&M

Required hold time (min)

Initial concentration source Initial concentration ci (%)

Mixing during the hold time

Will anything keep the air moving after discharge — AHU or CRAC units left running, strong heat sources, fans? This decides which equation applies (E.2.5.2).

What runs during hold time, and how you confirmed it (required)

Sketch plan and photos

Show the room and its surroundings, doors, ducts, dampers and drains, and whether each is open or closed during the hold time (E.2.5.1). A photo of a hand sketch is fine. Up to 6 photos.

Add photo Status of doors, dampers and plant during the hold time

Equipment

Fan Gauge

Conditions

Inside temp Te (°C) Outside temp To (°C) Atmospheric Pt (bar) from the DG-1000

Bias during fan test Pbt (Pa) fan sealed, +ve if inside higher Bias under hold-time conditions Pbh (Pa) lower minus upper for heavy agents

Leakage opening area of the fan doorway in hold-time condition (m²) leave blank if the door seals

Pre-test checklist

Pressurisation

Five readings, spaced from the highest stable pressure (prefer ≤ 60 Pa) down to 10 Pa or 10|Pbt|, whichever is higher. Enter the room pressure as read (with bias); the app removes Pbt.

Depressurisation

Leakage characteristic

Bias after the fan test

Bias pressure repeated with the fan sealed, Pbt (Pa) E.2.7.4.5: more than 1 Pa different from the first reading means repeat the test

Field calibration check

E.2.7.5: fit a plate with a known hole, about half the room's ELA, and repeat the readings. The fan's measurement of the hole must be within ±15 % of its real area.
