scope:

This standard encompasses the design and performance requirements for rotary gear type, positive displacement fire pumps for use in fire protection systems. Certification is limited to such pumps which have a rated pressure of a minimum of 40 psi (2.75 bar). In cases where metric size pumps are to be examined for certification, test criteria comparable to the United States equivalent size shall be used.

Requirements for other types of fire pumps are detailed in the following Standards:

Class 1310 Multi-Stage, Multi-Outlet Type

Class 1311 Horizontal Split Case Centrifugal Type

Class 1312 Vertical Shaft Centrifugal Turbine Type

Class 1319 Horizontal End-Suction Centrifugal Type

Class 1370 Vertical Turbine Barrel Centrifugal Type

Class 1371 In-Line Centrifugal Type

Purpose

This standard states testing and certification requirements for rotary gear type, positive displacement fire pumps that supply water and/or foam concentrates to water mist or foam fire protection systems. These pumps must be available for many years to operate reliably at rated capacities and pressures during emergency fire incidents, despite being idle for extended periods.

Testing and certification criteria may include, but are not limited to, performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a surveillance audit program.
