Note:
1. The regulator shall be tested at inlet pressures of 5,8,15,30,90 and 120 psig at each of the above conditions, except as follows:
a. At an inlet pressure of 5 psig, flowrates above 75 lpm shall not be required.
b. At an inlet pressure of 8 psig, flowrates above 100 lpm shall not be required.
2. Fluctuations in output flow shall not be permitted.
3. The conditions and requirements listed above pertain to first article and qualification testing as described in 4.8.2.2.1 and 3.6.2.2.1, respectively. Conditions and requirements for quality conformance inspection, quality conformance verification inspection, environmental exposure testing, and post environmental exposure are listed in Table IV.
