Peak Flow

[Mech]

Here we go again . . . I searched the archives but found nothing.

2009 IPC

604.3 Water distribution system design criteria. The water distribution system shall be designed, and pipe sizes shall be selected such that under conditions of peak demand, the capacities at the fixture supply pipe outlets shall not be less than shown in Table 604.3.

What is peak demand? Is it all the fixtures being used simultaneously?
