d. For use with natural, manufactured, mixed and liquefied petroleum gases and LP gas air mixtures; and

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

If a valve 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 specification.
