Description / Abstract:
This ARP covers a procedure to be used in the determination of
0.05 to 0.3 ppm of chlorine in oxygen from any type of generator
used for emergency or life-support systems. The methyl orange
method described can be considered as a referee technique.
Purpose:
This ARP describes a method for rapid and reliable measurement
of chlorine in oxygen from a solid chemical oxygen generator. The
method of sampling and analysis used in this procedure is adequate
to encompass the range of interest relevant to the 0.3 ppm limit
set for chlorine in oxygen. The test is sufficiently flexible to
make the determination during a part of or for the first 60 s after
activation, since this is the usual time during which chlorine may
be found in the oxygen being generated.
