NFPA 24-2016: 10.10.2.5 Backflow Prevention Assemblies.
10.10.2.5.1 The backflow prevention assembly shall be forward flow tested to ensure proper operation.
10.10.2.5.2 The minimum flow rate tested in 10.10.2.5.1 shall be the system demand, including hose stream demand where applicable.
My question is:
When is hose stream demand applicable? Is this referring to inside hose streams or all hose streams?
