Attachment 3 -Master Template for Stair 3 Pressurization Records.xlsx

This is a testing and inspection template for staircase pressurization system maintenance records. The template is designed to document performance data during testing visits to the U.S. Embassy London's Staircase Pressurization systems (COLT). The spreadsheet captures measurements across multiple parameters including stair-to-lobby pressure differential, lobby-to-corridor pressure, lift-to-lobby pressure, mean air velocity, and door opening force (measured in kilograms) for corridor-to-lobby and lobby-to-stair measurements. Testing is conducted on multiple floors with rows numbered 1-11 available for data entry.

The template establishes specific performance targets that must be maintained during testing: stair/lobby and lift/lobby pressure differentials between 5-45 Pa, corridor/lobby pressure between 42-51 Pa, mean air velocity between 2.0-3.2 m/s, and corresponding door opening force measurements. Users are instructed to copy this template into a new sheet labeled with the testing date in DD.MM.YYYY format and complete measurements on-site. All completed sheets must be retained within the workbook to maintain a historic record as required by BS 12101 standards. The template also notes that floor selection should vary across testing visits to ensure comprehensive system monitoring.
