Describes methods for testing aerosol samplers under prescribed laboratory conditions, and performance requirements that are specific to aerosol samplers. These performance requirements, which include conformity with the EN 481 sampling conventions, apply only to the process of sampling the airborne particles from the air, not to the process of analyzing particles collected by the process of sampling. Although analysis of samples collected in the course of testing is usually necessary in order to evaluate the sampler performance, the specified test methods ensure that analytical errors are kept very low during testing and do not contribute significantly to the end result. The determination of analytical errors and factors related to them (for example the bias, precision and limit of detection of the analytical method) is outside the scope of this standard. Where the aerosol sampler requires the use of an external (rather than integral) pump, the pump is not subject to the requirements of this standard.
