Dry-Barrel Fire Hydrants
|Publication Date:||24 October 2018|
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.
Exceptions. This standard does not cover the wet-barrel or flushtype of hydrants. (For wet-barrel type, see ANSI/AWWA C503. For flush-type, see AWWA Manual M17.) This standard, ANSI/AWWA C502, does not provide instructions for installation of fire hydrants. For installation information, see ANSI/AWWA C600 and AWWA Manual M17.
The purpose of this standard is to provide the minimum requirements for dry-barrel fire hydrants for fire-protection service, including materials, general design, and testing.
