Method for determination of pesticide bulk density1 ScopeThis standard specifies the method for determining the bulk density and real density of pesticides. This standard is applicable to the bulk density and solid density of solid preparations such as granules and water dispersible granules.2 terms and definitionsThe following terms and definitions apply to this document. 2.1 Bulk density bulkdensity The bulk density of the solid matter, including bulk density and true density. 2.2 Pine density pourdensity A certain amount of solid material without any sinking power, loose placed in the standard size of the container density. 2.3 Real density tapdensity The density of the solid matter placed in the standard gauge container after vibration or tapping under standard conditions.3 test method3.1 Method Summary First, a solid sample of known mass is placed in a standard gauge graduated cylinder to measure the bulk density thereof; and then the cylinder is raised 25mm distance, vertical drop to a rubber base pad, so repeat 50 times, measuring the volume of real density. 3.2 Instruments 3.2.1 with plug cylinder. range 250mL, the accuracy of at least ± 2mL, from 25mL ~ 250mL scale value of the minimum scale value of 2mL, The distance from 0 to 250 mL is 22 cm to 24 cm. 3.2.2 rubber base pad. with 35 to 50 international rubber hardness (IRHD), or other similar hardness of the material, such as chloroprene rubber sheet. 3.2.3 wax paper. 3.2.4 stopwatch. 3.2.5 Balance. accuracy of at least 0.1g. 3.2.6 drop box. should be placed in a hard and solid test bench. 3.3 Determination steps Place the sample on wax paper, form the wax paper into a chute, slowly and slowly slide the sample into a known mass at about 45 ° bevel The amount of the cylinder, up to about 90% of the cylinder marked volume, gently flatten the sample surface, do not shake the cylinder, measuring its volume (accurate to 2 mL) and then weighed the mass of the sample (accurate to 0.1 g). Cover the rubber stopper and carefully drop the graduated cylinder into the solid density measuring device Inside the box (see Figure 1), gently grasp the upper part of the cylinder, increase the speed of 25mm (in the process of increasing the speed of about 10 degrees to help the sample formation level ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 33810-2017_English be delivered?Answer: Upon your order, we will start to translate GB/T 33810-2017_English as soon as possible, and keep you informed of the progress.
