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. Approval 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 Approval, 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.

Approval Standards are intended to verify that the product described will meet stated conditions of performance, safety, and quality useful to the ends of property conservation.

Purpose

This standard states Approval criteria 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.

Approval criteria may include, but are not limited to, performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a follow-up program.
