Historical Version s – view previous versions of standard Translated Version s: Several manufacturers of testing equipment now have units based on these principles. 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.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution asrm accessing standards. 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. A particle size distribution which ends abruptly at the detection limit of the instrument may indicate that particles outside the range are present.

No other units of measurement are included in this standard. Please first log in with a verified email before subscribing to alerts.

For example, kaolinite measured at You may delete a document from your Alert Profile at any time. Add to Alert PDF. 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. 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.

Extrapolation, interpolation, or estimation to the wavelength of the laser being used can therefore be made. Therefore, comparison of results from different instruments may be misleading.

The results are strongly influenced by physical principles employed by each method of particle size analysis. 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. No other units of measurement are included in this standard.

Your Alert Profile lists the documents that will be monitored. These differences include lasers of different wavelengths, detector configuration, and the algorithms used to convert scattering to particle size distribution.
