# §3175.142. Required static tests.

- (a) **Instantaneous flow rate.** The instantaneous flow rates must meet the criteria in [§ 3175.141(d)](/cfr/43/3175.141.md?p=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.
- (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)](/cfr/43/3175.141.md?p=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)](/cfr/43/3175.104.md?p=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.
