ASTM-F751 › Standard Test Method for Measuring Particle Size of Wide-Size Range Dry Toners (Withdrawn 2003)
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers a dual-aperture particle size analysis using an electronic sensing zone apparatus. Dry inks, toners, etc., are covered. Particles as small as 1.0-[mu]m diameter and as large as 80-[mu]m diameter in a single powder system can be analyzed.
1.2 This test method is for particulate systems having a size range greater than 20 to 1, therefore requiring two apertures. For applications where particle size difference is between 1.4 [mu]m and 80 [mu]m and having a 20 to 1 or less size range, the simpler procedure found in Test Method F577 should be used.
1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. 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.
