32、) BSI EN 13205:2001 (E) 5 Introduction EN 481 defines sampling conventions for the particle size fractions to be collected from workplace atmospheres in order to assess their impact on human health. Conventions are defined for the inhalable, thoracic and respirable aerosol fractions. These conventio
33、ns represent target specifications for aerosol samplers, giving the ideal sampling efficiency as a function of particle aerodynamic diameter. In general, the sampling efficiency of real aerosol samplers will deviate from the target specification, and the aerosol mass collected will therefore differ
34、from that which an ideal sampler would collect. In addition, the behaviour of real samplers is influenced by many factors such as external wind speed, that depend on the environment in which the sampler is used.

35、lled Copy, (c) BSI EN 13205:2001 (E) 6 1 Scope This European Standard specifies methods for testing aerosol sampling instruments under prescribed laboratory conditions, and performance requirements that are specific to aerosol sampling instruments. These performance requirements, which include confo
36、rmity with the EN 481 sampling conventions, apply only to the process of sampling the airborne particles from the air, not to the process of analysing particles collected by the process of sampling. Although analysis of samples collected in the course of testing is usually necessary in order to eval
37、uate 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
38、 the analytical method) is outside the scope of this standard. Where the aerosol sampling instrument requires the use of an external (rather than integral) pump, the pump is not subject to the requirements of this standard. EN 482 contains general performance requirements for methods used for determ
39、ining the concentrations of chemical agents in workplace atmospheres. These performance requirements include maximum values of overall uncertainty (a combination of precision and bias) achievable under prescribed laboratory conditions for the methods to be used. The requirements of EN 482 apply to t
40、he combined results of sampling airborne particles and analysing collected particles. This standard specifies how the performance of aerosol measurement methods is assessed with respect to the general requirements of EN 482, through the combination of sampling and analytical errors. This standard ap
41、plies to all instruments used for the health-related sampling of particles in workplace air, whatever their mode of operation. Different test procedures and types of evaluation are included to enable application of this standard to a wide variety of instruments. The standard should enable manufactur
42、ers and users of aerosol sampling instruments to adopt a consistent approach to sampler validation, and provide a framework for the assessment of sampler performance with respect to EN 481 and EN 482. It is the responsibility of the manufacturer of aerosol samplers to inform the user of the sampler
43、performance under the laboratory conditions1) specified in this European Standard. It is the responsibility of the user to ensure that the sampler complies with the overall uncertainty requirements of EN 482 under the actual conditions of use. 2 Normative references This European Standard incorporat

The tests required to assess performance are therefore limited to these
48、 conditions. Should such large particle sizes or wind speeds actually exist at the time of sampling, it is possible that different samplers meeting this standard may give different results.
