scope:

This standard applies to systems that measure water elevations (i.e. static and rate of change types), rainfall, water flow, presence of water, soil moisture, etc. The equipment in this standard may include multiple sensors..

Communication between the equipment and the network infrastructure may be accomplished using industry protocols (i.e. ALERT, ALERT2, IoT, IIoT.) and/or proprietary software.

Early warning flood sensor systems used in this standard support the bidirectional transmission of sensor data via network topographies such as direct communication, node to node, mesh, star, etc. Systems may incorporate one or multiple technologies to ensure ability to transmit and receive data.

The equipment included in this standard may be powered by one or more means such as: electrical service, secondary (rechargeable) battery with solar panel, or by primary (non-rechargeable) battery.

The equipment included in this standard may be stand alone or housed within one or multiple enclosures to protect the components from the environment.

The equipment included within this standard may be mounted directly to a structure or a pole. Installations may result in all components being installed in close proximity or separated as needed to provide for easier access for maintenance and protection from the natural or human environment.

The requirements of this standard shall be used to measure and describe the performance, security and reliability of early warning flood sensor systems in a controlled test environment.

Purpose

This standard states testing and certification requirements for early warning flood sensor systems that automatically sense and transmit data on programmed intervals.

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 program.
