•	V is volume in liters,  PS is pressure in bars,  DN is nominal dimension number (no units)
•	Watch out for exact border values, such as PS*V = 25 for table 1 category 1, I am not certain if ">" or "" is correct.
•	Category limits are the 'entry' limits and do not contain the 'top' limits. Once you verify you fall within a least category 1 for a particular table, check to see if you might fall into each higher category 
•	Some values were calculated from data given in the tables and they have not been drawn to scale in the tables themselves.
•	Example follow for some tables. If the example is in the far left column it means the system may have the described characteristics and not even enter the tables first category.

Water distribution tubing that operates below 145 psi (any diameter tubing)
OR any pressure where tubing is below 8inch diameter.		

30 psi = 2.07 bar
90 psi = 6.21 bar
120 psi = 8.27 bar
2000 psi = 137.9 bar

1/8 tubing = approx DN 3 ??
1/4 tubing = approx DN 6
1/2 tubing = approx DN 15
3/4 tubing = approx DN 20
1 inch tubing = approx DN 25

Gas bottles typically contain Group 1 materials (toxic, flammable, etc….)
Gas bottles have water volumes of 2.3 to 6.9 liters.

Argon would be a Group 2 fluid.
