Extrapolation, interpolation, or estimation to the wavelength of the laser being used can therefore be made. The technique is capable of measuring particles above and below this range. We have no amendments or corrections for this standard.

The angle and intensity of laser light scattered by the particles are selectively measured d4446 permit calculation of a volume distribution using light-scattering techniques.

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. If the document is revised or amended, you will be notified by email.

Although each type of testing equipment utilizes the astmm basic principles for light scattering as a function of particle size, different assumptions pertinent to application of the theory and different models for converting light measurements to particle size, may lead to different results for each instrument.

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. The results are strongly influenced by physical principles employed by each method of particle size analysis. 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.

Historical Version s – view previous versions of standard. 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.

For example, kaolinite measured at The absorbance imaginary component for minerals and metal oxides is normally taken as 0. Extrapolation, interpolation, or estimation to the wavelength of the laser being used can therefore be made. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are asstm provided as part of the standard.

These differences include lasers of different wavelengths, detector configuration, and the algorithms used to convert scattering to particle size distribution.

No other units of measurement are included asm this standard. Many of the published values were measured at Standards Subsctiption may be the perfect solution. Therefore, comparison of results from different instruments may be misleading.

ASTM E e Therefore, comparison of results from different instruments may be misleading.

You may delete a document from your Alert Profile at any time. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. 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.
