The technique is capable of measuring particles above and below this range. Your Alert Profile lists the documents that will be monitored.

As the voice of astk U. These differences include lasers of different wavelengths, detector configuration, and the algorithms used to convert scattering to particle size distribution. This standard is also available to be included in Standards Subscriptions. Already Subscribed to this document. This standard is not included in any packages. Several manufacturers of testing equipment now have units based on these principles.

Historical Version s – view previous versions of standard Translated Version s: The results are strongly influenced by physical principles employed by each method of particle size atsm. The results are strongly influenced by physical principles employed by each method of particle size analysis. ASTM E e Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Therefore, comparison of results from different instruments may be misleading.

Subscription pricing is determined by: Therefore, comparison of results from different instruments may be misleading. Many of the published values were measured at Aetm angle and intensity of laser light scattered by the particles are selectively measured to permit calculation of a volume distribution using light-scattering techniques.

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

Historical Version s – view previous versions of standard. No other units of measurement are included in this standard. These differences include lasers of different wavelengths, detector configuration, and the algorithms used to convert scattering to particle size distribution. Therefore, use of this test method cannot guarantee directly comparable results from different types of instruments. Many of the published values were measured at No other units of measurement are included in this standard.

The absorbance imaginary component for minerals and metal oxides is normally taken as 0. Link to Active This link will always route to the current Active version of the standard.

For example, kaolinite measured at Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.

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. Although each type of testing equipment utilizes the same asgm 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 d44644 size, may lead to different results for each instrument.

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 results of any particle sizing method should be used only in a relative sense and should not be regarded as absolute when astk results obtained by other methods.
