Therefore, comparison of results from different instruments may be misleading. Link to Active This link will always route to the current Active version of the standard.

This standard is also available to be included in Standards Subscriptions. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. No other units of measurement are included in this standard. D44644, interpolation, or estimation to the wavelength of the laser being used can therefore be made. The absorbance imaginary component for minerals and metal oxides is normally taken as 0.

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. The angle and intensity of laser light scattered by the particles are selectively xstm to permit calculation of a volume distribution using sstm techniques.

Therefore, comparison of results from different instruments may be misleading. 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. If the document is revised or amended, you will be notified by email.

The absorbance imaginary component for minerals and metal oxides is normally taken as 0. 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.

A particle size distribution which ends abruptly at the detection limit of the instrument may indicate that particles outside the range astj present. These differences include lasers of different wavelengths, detector configuration, and the algorithms used to convert scattering to particle size distribution.

Although each type of asgm 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 lead to different results for each instrument.

Many of the published values were measured at ASTM E e The technique is capable of measuring particles above and below this range. 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.
