JB/T 12630-2016 《Test method for softening point of electrostatic dry toner》 Related products

This standard specifies the test conditions, test procedures and test reports for the softening point of electrostatic copying dry toner. It is suitable for the measurement of the softening point of electrostatic copying toner, including toner in dry single component and dry two component developer. The test principle adopts the method of temperature rise Flow rate determination. By heating the toner sample at constant speed, it is melted and discharged under specified conditions. The softening Linear dispersion is plotted and the softening point is determined by the Rheometer. The test environmental conditions are temperature 18 ° C~ 28 ° C, relative humidity 40%~ 60%. The test instrument mainly includes capillary tubing Rheometer.
