Dust particle counter calibration specification
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 wor
