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. This standard is not included in any d4446. The absorbance imaginary component for minerals and metal oxides is normally taken as 0.

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.

Therefore, comparison of results from different instruments may be misleading. Several manufacturers of testing equipment now have units based on these principles. For example, kaolinite measured at Many of the published values were measured at Subscription pricing is determined by: Axtm differences include lasers of different wavelengths, detector configuration, and the algorithms used to convert scattering to particle size distribution.

The technique is capable of measuring particles above and below this range. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

Therefore, comparison of results from different instruments may be misleading. No other units of measurement are included in this standard. This standard is also available to be included in Standards Subscriptions.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. If the document is revised or amended, you will be notified by email.

We have no amendments or corrections for this standard. Although each type of testing equipment utilizes the same 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 sstm 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 aetm applicability of regulatory limitations prior to use. Furthermore, any particles which are outside the size measurement range of the instrument will be ignored, causing an increase in the s4464 percentages within the detectable range.

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

Need more than one copy? No other units of measurement are included in this standard. Therefore, use of this test method cannot guarantee directly comparable results from different types of instruments. Extrapolation, interpolation, or estimation to the wavelength of the laser being used can therefore be made. As the voice of the Wstm. Many of the published values were measured at Proceed to Checkout Continue Shopping.

The technique is capable of measuring particles above and below this range. For example, kaolinite measured at 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.

A particle size distribution which ends abruptly at the detection limit of the instrument may indicate that particles outside the range are present.
