It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Extrapolation, interpolation, or estimation to the wavelength of the laser being used can therefore be made.

The angle and intensity of laser light scattered by the particles are selectively measured to permit calculation of a volume distribution using light-scattering techniques. ASTM E e These differences include lasers of different wavelengths, detector configuration, and the algorithms used to convert scattering to particle size distribution. This standard is not included in any packages.

The technique is capable of measuring particles above and below this range. Furthermore, any particles which are outside the size measurement range of the instrument will be ignored, causing an increase in the reported percentages within the detectable range. As the voice of the U. The absorbance imaginary component for minerals and metal oxides is normally taken as 0.

Standards Subsctiption may be the perfect solution. The results are strongly influenced by physical principles employed by each method of particle size analysis. The technique is capable of measuring particles above and below this range. Historical Version s – view previous versions of standard. The results of any particle sizing method should be used only in a relative sense and should not be regarded as absolute when comparing results obtained by other methods.
