1 Scope

This standard applies to laser light scattering particle counter (hereinafter referred to as particle counter) calibration.

2 Terms

2.1 monodisperse particles (monodisperseparticle) A group of polystyrene spherical particles, the particle diameter distribution of relative standard deviation ≤5%, see Appendix A. 2.2 diameter (particlesize) Certain air of discrete particle diameter (short diameter), with the intensity of the scattered light corresponding to a monodisperse particle The diameter of the sub-unit μm. Particle diameter in the measured particle counter (0.1 to 10) μm range. 2.3 particle concentration (particleconcentration) Within a predetermined sampling time and sampling flow, measured in the presence of air per unit volume of from less than a specified diameter The number of scattered particles. 2.4 size distribution error (errorofparticlesize) Particle counter for different size particles in aerosols percentage measurement error measurements.

3 Overview

Particle counters measure the particle size and particle concentration is clean air in discrete particles, to determine the clean room and clean Cleanliness level of the instrument environment. Dust particle counter can be used for measuring the dust content, as well as clean bench and Filter performance testing. Particle Counter mainly by the gas system, an optical system, a data processing system components. It works They are. airborne particles scattering of incident light has the intensity of the scattered light related to particle size. Containing dust particles Air from the dust particle counter sampling oral inhalation, through the light sensitive areas, dust particles irradiated by light scattering and the The particle size into a certain ratio between the optical pulse signal, the signal is accepted and converted into corresponding electrical pulse photosensor Signal is further amplified by a detection cycle electrical pulse count per unit volume that can be sampled in the air The number of dust particles, ie particle concentration.

4 Metrological characteristics

4.1 appearance requirements No defects affect the calibration results. the parts should be complete and reliable connection, should not affect the use of the damage and Deformation; various knobs and switches without injury and stuck phenomenon. 4.2 Insulation resistance Instrument insulation resistance of not less than 20MΩ. 4.3 Electric strength ......
