National and European legislation, such as vehicle emissions regulations, dictates that emission gases are routinely measured to exacting standards. In order to achieve this, it is necessary to use accurate and traceable gas standards. These standards can also be used for petrol, diesel and gas turbine engine research, as well as a wide range of development and certification work.
NPL provides gas standards for calibrating vehicle emissions monitors, which can be prepared to the requirements of the customer. The table below gives an indication of the available mixtures, others may be available on request.
NPL also has a range of particle measurement capabilities to support the quantification of vehicle particulate emissions and the calibration of equipment used to perform those measurements. Further details can be found here.
