Flir received third-party validation of the GF-Series and G-Series cameras' compliance with the following sensitivity standards.
For the NSPS OOOOa and OOOOb methane rules laid out by EPA:
Your optical gas imaging equipment must be capable of imaging a gas that is half methane, half propane at a concentration of 10,000 ppm at a flow rate of ≤60 g/hr from a quarter inch diameter orifice.
For Appendix K to 40 CFR Part 60:
Your optical gas imaging equipment must be capable of detecting methane emissions at a rate of 19 g/hr, detecting either n-butane emissions at 29 g/hr or propane emissions at 22 g/hr, and performing at a viewing distance of 2 meters with a delta-T of 5°C in calm wind conditions (≤1 meter/second).
