Is there any drainage hose standard for dishwashers in US?

It is very important for me to understand if the drainage hose has to be smooth inside or corrugated.
Do you know any standards related to this issue?
Thanks in Advance!

I have not heard of any "standards" for it but assume a smooth interior should allow easier draining, which is the point of the hose in the first place, and help prevent sediment buildup in it.

A corrugated exterior might help to prevent kinking.

That doesn't look smooth on the inside at all, but corrugated. It also looks pretty pliable. But if it's what the manufacturer supplied with the dishwasher...

What's the make and model of the dishwasher? If you post it we can look up what hose is supplied with it.
