This is a report that describes the work carried out to-date on a review of the methods for the on-site/field calibration (OS/FC) of particle measuring instruments. The package of work, also relates to the identification and review of current methods of calibration, and the application areas where these methods are used.
A review of standards and scientific literature has been carried out, taking account of the needs of UK industry and information gained from on-going contacts with scientists working in the
field of aerosol science.
A number of areas that make use of OS/FC have been identified. Only a little information related to OS/FC has been published. Most of the available information is directed towards the OS/FC of direct reading continuous mass monitors used for stack emissions.
The most favoured OS/FC method was found to be that which compares the measured sample with a reference gravimetric, 'real emission' sample collected from the same source at the same time using a well-characterised extractive isokinetic sampling procedure.
