This test is useful in determining particle size characteristics of dry toners used in electrostatic imaging devices such as copiers and laser printers. It is a practiced method for use in quality control of toner particle size.
1.1 This test method covers aperture particle size analysis using an electronic sensing zone apparatus provided with a digital pulse processor. Dry inks, toners, and so forth, are covered. Particles as small as 1 m and as large as 120 956;m can be analyzed.
1.2 This standard does not purport to address all of the safety concerns, 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.
