(e) For use on gas piping systems having fuel gas pressures not in excess of 1/2 psi (3.45 kPa).

1.1.3  
If a value for measurement as given in this standard is followed by an equivalent value in other units, the first stated value is to be regarded as the requirement.

1.1.4  
All references to psi throughout this standard are to be considered gage pressure unless otherwise specified.
