First published in.2009 as GB/T 22838.7-2009; This is the first revision. -IntroductionThe physical properties of cigarettes and filter rods are important indicators for evaluating the quality of cigarette production and processing. GB/T 22838 "Physical Properties of Cigarettes and Filter Rods" The Determination of Detection Methods is planned to consist of 16 parts according to different detection objects and detection methods. Part 1.Cigarette packaging and labeling. The purpose is to specify the measurement methods for cigarette packaging labeling and cigarette packaging. Part 2.Photoelectric method for length. The purpose is to specify the photoelectric method for the determination of the length of cigarettes and filter rods. Part 3.Non-contact optical method for circumference. The purpose is to specify the non-contact optical determination of the circumference and ovality of cigarettes and filter rods. method. Part 4.Cigarette quality. The purpose is to specify the method for determining the quality of cigarettes. - Part 5.Cigarette draw resistance and filter rod pressure drop. The purpose is to specify the measurement method and standard of cigarette draw resistance and filter rod pressure drop condition. Part 6.Hardness. The purpose is to specify the method for determining the hardness of cigarettes and filter rods. - Part 7.Cigarette dust content. The purpose is to specify the method for determining the dust content of cigarettes. Part 8.Moisture content. The purpose is to specify the method for determining the moisture content of cigarettes and filter rods. - Part 9.Cigarette Empty Heads.

The above documents clarify the scope of application, terms and definitions, test equipment and procedures, and have been repeatedly tested and verified by multiple laboratories. The verification provides precision data, enhances the consistency and comparability of test results, and provides a scientific and rigorous standard for the detection of physical indicators of cigarettes. Standardized basis. Cigarette dust content is one of the important indicators for measuring the physical properties of cigarette products. GB/T 22838.7-2009 has been issued and implemented for more than ten years. It provides important means and methods for the quality control of cigarette products and promotes the improvement of product quality. The main changes include the addition of the determination method principle, the optimization of the sieve movement mode, and the adjustment of the standard expression method. The revised standard test requirements are more scientific. It is scientific and rigorous, and can further improve the evaluability of cigarette dust content detection indicators. Determination of physical properties of cigarettes and filter rods Part 7.Cigarette dust content1 ScopeThis document describes the method for the determination of dust content in cigarettes. This document is applicable to the determination of dust content in cigarettes.2 Normative referencesThe contents of the following documents constitute the essential clauses of this document through normative references in this document.

GB/T 8170 Rules for rounding off values and expression and determination of limit values GB/T 16447 Atmospheric environment for conditioning and testing of tobacco and tobacco products3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 Crank A component that can make a full circle rotation and is used to make the screen produce reciprocating motion. 3.2 Connecting rod A component that connects the crank and the screen and transmits the force of the crank to the screen. 3.3 Pendulum rod A component that connects the screen and realizes the swing of the screen under the drive of the crank connecting rod.4 PrincipleWeigh the shredded tobacco and place it on the screen. Swing the screen at a specified amplitude and frequency within a certain period of time to sift out the corresponding tobacco powder. The cigarette dust is weighed and the percentage of the mass of cigarette dust to the mass of tobacco is calculated, which is the cigarette dust content. 5.Instruments and Equipment 5.1 The cigarette dust content tester consists of a screen, a pendulum, a connecting rod, a crank, a weighing unit and a control unit, as shown in Figure 1. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 22838.7-2024_English be delivered?Answer: Upon your order, we will start to translate GB/T 22838.7-2024_English as soon as possible, and keep you informed of the progress.
