In Plumbing jargon, "schedule 40" refers to the thickness of the pipe wall. Specifically, it indicates a standard measurement for the thickness of PVC (polyvinyl chloride) pipes and fittings. Schedule 40 pipes are commonly used for residential and commercial plumbing applications due to their durability and ability to withstand high pressure.

The difference between schedule 40 and 80 pvc is the wall thickness and schedule 80 is thicker then schedule 40 so the higher the schedule number the thicker the wall of the pipe thus can hold more pressure.
It is the wall thickness heavier then schedule 20 lighter then schedule 80

Schedule 40 PVC is a type of plastic pipe that is commonly used in plumbing and construction projects. It is known for its durability, affordability, and ease of installation. In plumbing, Schedule 40 PVC is used for water supply lines, drainage systems, and vent pipes. In construction, it is used for electrical conduit, irrigation systems, and other applications where a strong and corrosion-resistant pipe is needed.
Not plumbing pvc pipe, but pvc pipe made especially for wiring.
No you shouldn't. It will fail inspection. Use electrical (grey) conduit. It is about the same price and has the proper electrical insulating properties required. The thicker PVC(schedule 40) is best, although schedule 80 is acceptable. (Schedule 40 is required for underground service feeders.)

Schedule 40 Foam Core pipe can be used for DWV systems, and Schedule 40 pressure rated pipe (PW) should be used for water lines, and can also be used for DWV. CPVC can also be used for water lines.
Schedule 40 PVC pipe is commonly used for plumbing and drainage systems in residential and commercial buildings. Its applications include water supply lines, irrigation systems, and underground piping for sewer and drainage systems.
schedule 40 is thicker than schedule 20
If you mean: 7 18 29 40 then the next term is 40+11 = 51
The difference in thickness is not by the ASTM grade, but rather by the term "Schedule" - as in Schedule's 10, 40, and 80 - with schedule 10 having the lighest wall thickness, and schedule 80 having the thickest.
That is not slang - 40 cal stands for 40 calories, which is a nutrition measurement.
The difference between schedule 40 and 80 pvc is the wall thickness and schedule 80 is thicker then schedule 40 so the higher the schedule number the thicker the wall of the pipe thus can hold more pressure.
