40 CFR 86.328-79 - Leak checks.
(1) Any location within the analysis system where a vacuum leak could affect the test results must be checked.
(2) The maximum allowable leakage rate on the vacuum side is 0.5 percent of the in-use flow rate for the portion of the system being checked. the analyzer flows and bypass flows may be used to estimate the in-use flow rates.
(3) The sample probe and the connection between the sample probe and valve V2 (Figure D79-1) may be excluded from the leak check.
(2) Option: If the flow rate for each flow meter is equal to or greater than the flow rate recorded in § 86.329(b)(1)(ii), then a pressure side leak check is not required.
