scope:

This standard encompasses the design and performance requirements for flood abatement equipment for use in controlling riverine or rainfall related flood conditions. Flood abatement equipment shall be FM Approved for specific flood protection applications which are designated and categorized by:

• Function (permanent, contingent, and emergency)

• Operation (automatic and manual)

• The intended use of protection (i.e., perimeter and opening barriers, flood abatement pumps and backwater valves)

Consultation with FM Global Property Loss Prevention Data Sheet 1-40 is required for installation of this equipment.

Flood waters can produce high hydrostatic or flood dynamic loading on a structure. Appropriate measures must be taken to ensure that an external wall structure (or similar) can withstand anticipated flood loading. Some wall construction assemblies often are able to withstand 3 ft (0.9 m) or less of flood loading without needing reinforcement or additional waterproofing.

Since each flood abatement system is unique in its operation and design, component testing shall be performed on a case-by-case basis. Upon request for a program, and receipt of appropriate system documentation, FM Approvals shall prepare a customized evaluation program for the specific flood abatement system. The test program shall verify the manufacturer's design calculations, stated performance requirements, as well as component functionality and reliability.

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 describes FM Approvals requirements for flood abatement equipment for use in riverine or rainfall related flood conditions.

FM Approvals criteria may include, but are not limited to, component and system testing performance requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a surveillance audit program.
