Which class of standpipe is associated with a 65 mm connection?

Explanation:
Standpipe classifications describe the size of the outlets and who uses them. A 65 mm connection is the 2.5-inch size, which is the standard outlet size for firefighter use on standpipes. That makes the class designed for fire department use with 65 mm outlets Class I. Other classes use different configurations: 38 mm (1.5 inch) hoses for occupant use, a combination of outlets and hoses in a Class III setup, and a large-diameter standpipe in the Class IV category. So a 65 mm connection aligns with Class I.
