Required static tests.

§ 3175.142 Required static tests. (a) Instantaneous flow rate. The instantaneous flow rates must meet the criteria in § 3175.141(d) for each test identified in Table 1 to this section, using the gas compositions identified in Table 2 to this section, as prescribed in Table 1 to this section. ER17NO16.071 ER17NO16.072 (b) Sums and averages. (1) Fixed input values from test 2 in Table 1 to this section must be applied for a period of at least 24 hours. (2) At the conclusion of the 24-hour period, the following hourly and daily values must meet the criteria in § 3175.141(d): (i) Volume; (ii) Integral value; (iii) Flow time; (iv) Average differential pressure; (v) Average static pressure; and (vi) Average flowing temperature. (c) Other tests. The following additional tests must be performed on the flow-computer software: (1) Each parameter of the configuration log must be changed to ensure the event log properly records the changes according to the variables listed in § 3175.104(c); and (2) Inputs simulating a 15 percent and 150 percent over-range of the differential and static-pressure transducer's calibrated span must be entered to verify that the over-range condition triggers an alarm or an entry in the event log.
