40 CFR 89.316 - Analyzer leakage and response time.
(a)Vacuum side leak check.
(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 (see Figure 1 in appendix B of this subpart) may be excluded from the leak check.
(c) The response time shall be accounted for in all emission measurement and calculations.
