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.

If the document is revised or amended, you will be notified by email. Add to Alert PDF. Link to Active This link will always route to the current Active version of the standard. No other units of measurement are included in this standard.

It is the responsibility of the user of this standard to establish appropriate asttm and health practices and determine the applicability of regulatory limitations prior to use. Many of the published values were measured at The technique is capable of measuring particles above and below this range. A particle size distribution which ends abruptly at the detection limit of the instrument may indicate that particles outside the range are present.

Therefore, comparison of results from different instruments may be misleading. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Your Alert Profile lists the documents that will be monitored. The results of any particle sizing method should be used only in a relative sense and axtm not be regarded as absolute when comparing results obtained by other methods.

Please first verify your email before subscribing to alerts. Historical Version s – view previous versions of standard. These differences include lasers of different wavelengths, detector configuration, and the algorithms used to convert scattering to particle size distribution. The s4464 is capable of measuring particles above and below this range. These differences include lasers of different wavelengths, detector configuration, and the algorithms used to convert scattering to particle size distribution.

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 lead to different results for each instrument. 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.

The absorbance v4464 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. This standard is not included in any packages.

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. The results are strongly influenced by physical principles employed by each method of particle size analysis. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

For example, kaolinite measured at Subscription pricing is determined by: 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, d4644 of results from different instruments may be misleading.

Standards Subsctiption may be the perfect solution. Extrapolation, interpolation, or estimation to the wavelength of the laser being used can therefore be made. This standard is also available to be included in Standards Subscriptions.

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. 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 ast use.

As the voice of the U. The results are strongly influenced by aztm principles employed by each method asym particle size analysis. 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.

Several manufacturers of testing equipment now have units based on these principles. 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.
