Note:
1. The regulator shall be tested at minimum inlet pressures of 5,8,15,30 and
80 +2/-0 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. Regulator inlet pressure, peak flow and outlet pressure shall be as defined in Figure 3.
3. Breathing inhalation and exhalation shall be sinusoidal (see 4.7.7.4).
4. The duration of testing shall be at least 1 minute.
