scope:

This standard encompasses the design and performance requirements for horizontal (axial) or vertical (radial), split-case type, centrifugal fire pumps for use in fire protection systems. Certification is limited to horizontal (axial) or vertical (radial), split-case type, centrifugal pumps which have a rated pressure of at least 40 psi (275 kPa). In cases where metric sized centrifugal fire pumps are to be examined for certification, test criteria comparable to the United States equivalent size shall be used.

This standard encompasses the requirements for single and multistage split-case fire pumps.

Purpose

This standard states testing and certification requirements for horizontal (axial) or vertical (radial), split-case type, centrifugal fire pumps that supply water to 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.
