GB/T 16913.5 Dust Resting Angle Tester Φ 80 × 250mm Injection Limited Bottom Method

ST-F13 Dust Resting Angle Tester

Resting angle (also known as angle of repose): refers to the acute angle between the inclined plane of dust accumulation and the horizontal plane at the bottom.

The ST-F13 dust angle of repose tester is designed and produced in accordance with the national standard GB/T 16913.5-1997 "Methods for testing the physical properties of dust - Part 5: Determination of angle of repose - Injection limited bottom method" (this standard refers to ISO 4324:1997 Powder and granular surfactants - Determination of angle of repose - Powder and particle).

The applicable measurement object of this device is dust, and the dust resting angle is measured using the injection limited bottom method. The main technical difference from ISO 4324:1997 is that it does not measure the height of dust accumulated on the limited bottom surface, but directly measures the dust resting angle using a protractor.

The working principle is sufficient for the dust overflowing from the material tray to be injected into the horizontal material tray through the funnel mouth; Measure the acute angle between the inclined plane of dust accumulation and the horizontal plane at the bottom, which is the dust resting angle.
