Formerly under the jurisdiction of Committee F05 on Business Imaging Products, this test method was withdrawn in June 2017 in accordance with Section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
Значение и использованиеThis 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.
Область применения1.1 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 μm and as large as 120 μm can be analyzed.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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.
