It depends your product application and requirement. If high level, 100ppm required, or even 2000ppm is also ok. There should have sensor detecting O2 ppm inside reflow.

If you are purchasing bottled nitrogen, your supplier should know the purity level.

Thanks Steve for mentioning the purity level ..,

Our purchase and sourcing team was asking us what is our expectation on purity level. Based on which they are checking with supplier.

So wanted to know any standard which is followed for the same.
