Valid Range of Gas Characteristics for AGA8 Methods
This table identifies the ranges of gas characteristics for which the AGA8
report can be used.
IMPORTANT
The mole percentage of each component, heating value
and relative density should not exceed the range which is
listed in table 1 of
Valid Range of Gas Characteristics for
AGA8 Methods on page 148 .
