It stands for Deutsches Normung=German standard and usually applies to dimensional information in the metric system. Hence DN50 is for 50mm.
its the thickness of the pipe wall
A pressure rating refers to the qualified operating pressure that is recommended for a component or a system by the manufacturer. The pressure rating of 12 schedule 40 steel pipe is 370 psi.
schedule is the thickness of the pipe and class is pressure/temperature rating of a fitting or pipe
No, they need to match.
pipe schedule is an American definition to define pipe thickness and how much pressure can the pipe stand, schedules are 10,20,40,80.., pipe schedule is nearly close to the eurobian definition for pipe class.

No
One definition of schedule is "a written or printed list, catalog, or inventory" (http://www.merriam-webster.com/dictionary/schedule). So pipe schedule simply refers to a list of wall thicknesses for given pipe sizes. More specific history can be found on wikipedia: http://en.wikipedia.org/wiki/Nominal_Pipe_Size#History
The term "DN50 valve" refers to a valve with a nominal diameter of 50 millimeters. "DN" stands for "Diameter Nominal," which is a standard measurement used in piping systems to indicate the size of the valve or pipe. DN50 valves are commonly used in various applications, including water and gas systems, to control the flow of fluids. The specifications may vary depending on the valve type and manufacturer.

A pressure rating refers to the qualified operating pressure that is recommended for a component or a system by the manufacturer. The pressure rating of 12 schedule 40 steel pipe is 370 psi.
Pipe schedule systems were used until hydraulic calculations became the norm in the mid 80's. You can tell if the system is pipe scheduled when the piping sizes decreases as you get farther away from the water source (sprinkler riser). The larger mains will reduce as less branch lines and sprinkjlers are being supplied.

No, they need to match.
Hydraulics pipe schedule refers to a standardized system that classifies the thickness and pressure rating of pipes used in hydraulic systems. The schedule number, such as Schedule 40 or Schedule 80, indicates the pipe's wall thickness, with higher numbers representing thicker walls that can withstand greater internal pressures. This classification helps engineers and technicians select appropriate pipes for specific applications, ensuring safety and efficiency in hydraulic systems.
