Validation of optical gas imaging 0000a
Gas Detection / Calibration
Information
NPL's miniature Controlled Release Facility (mini-CRF) provides a system to test compliance of Optical Gas Imaging cameras to the OOOOa standard. It contains an array of Mass Flow Controllers (MFCs) that control the flow of gas from cylinders of propane and methane and a balance gas of air or nitrogen. These are used to achieve the required test gas mix by dynamic dilution, following guidance in BS EN ISO 6145-7:2010.
In addition to the mini-CRF, NPL can also provide other controlled sources of emissions for testing and training purposes. This includes the larger CRF facility for fugitive emissions system validation and the leak simulation facility that can generate controlled gas leaks from a wide range of realistic sources, including pipe flanges.
