ASTM Methods – Particle Size Analysis | Micromeritics

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 adtm each instrument.

Subscription pricing is determined by: 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.

No other units of measurement are included in this standard. 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. Please first verify your email before subscribing to alerts. The absorbance imaginary component for minerals and metal oxides is normally taken as 0.

ASTM Methods – Particle Size Analysis

The technique is capable of measuring particles above and below this range. Therefore, comparison of results from different instruments may be misleading. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

The results are strongly influenced by physical principles employed by each method of particle size analysis. A particle size distribution which ends abruptly at the detection limit of the instrument may indicate that particles outside the range are present. For example, kaolinite measured at Historical Version s – view previous versions of standard. The technique is capable of measuring particles above and below this range. Many of the published values were measured at Link to Active This link will always route to the current Active version 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. ASTM E e Therefore, use of this test method cannot guarantee directly comparable results from different types of instruments. Proceed to Checkout Continue Shopping. The absorbance imaginary component for minerals and metal oxides is normally taken as 0.

Many of the published values were measured at The technique is capable of measuring particles above and below this range. As the voice of the U.

Therefore, comparison of results from different instruments may be misleading. We have no amendments or corrections for this standard.

Add to Alert PDF. 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.
