AWWA C502-18

This standard describes post-type, dry-barrel fire hydrants with compression shutoff (opening against or with the pressure) or gate shutoff for use in fire protection service in all climates, including those where freezing occurs.

This standard can be referenced in specifications for purchasing and receiving dry-barrel fire hydrants for fire protection service and can be used as a guide for evaluating materials and designing, testing, and inspecting dry-barrel fire hydrants. The stipulations of this standard apply when this document has been referenced and then only to dry-barrel fire hydrants for water supply service.
