The standpipe system demand shall be based on the design criteria in effect at the same time of __________

• A. Testing
• B. Installation
• C. Commissioning
• D. Maintenance

Answer: (B)

The main idea is that the hydraulic demand for a standpipe system is set by the design criteria that were in effect when the system was installed. Those criteria establish the required fire flow and pressure, as well as the system configuration, which drive the calculations for pipe sizing and outlet requirements. Once installation is complete, commissioning and testing verify that the system meets those established criteria, and maintenance keeps it operating, but they don’t redefine the original demand. So the demand should be based on the design criteria in effect at the time of installation.
