Foreword

GB/T 22838 "cigarettes and filter rods - Determination of physical properties" is divided into 18 parts. --- Part 1. cigarette packaging and labeling; --- Part 2. Photoelectric length method; --- Part 3. circumferential laser method; --- Part 4. quality of cigarettes; --- Part 5. Draw resistance of cigarettes and filter rods pressure drop; --- Part 6. hardness; --- Part 7. Cigarettes dust rate; --- Part 8. moisture content; --- Part 9. Cigarettes short; --- Part 10. population explosion; --- Part 11. Cigarettes extinguish; --- Part 12. Cigarettes appearance; --- Part 13. Filter Rod roundness; --- Part 14. filter rod appearance; --- Part 15. Cigarettes - Determination of ventilation - Definitions and measurement principles; --- Part 16. Cigarettes - Determination of loss of tobacco from the ends of the rotating cage method; --- Part 17. Determination of tobacco cigarette ends dropped vibration method; --- Part 18. Cigarettes - Determination of loss of tobacco from the ends of the rotating box method. This section GB/T 22838 Part 3. The partial modification of the use of ISO 2971.1998 "Cigarettes and filter rods - Determination of nominal diameter of the laser method" (in English). This section according to ISO 2971.1998 redrafted. Taking into account China's national conditions, this portion of the ISO 2971.1998 the presence of a small amount of technical differences, these technical differences have been incorporated into the text, and They are involved in terms of the margin identified by a single vertical line. This portion of the ISO 2971.1998 compared to the main technical changes are as follows. --- Consistent with GB/T 5606.1, 7.3 in this section of the sample size was increased to 30. --- Consistent with GB/T 16447, Part A. 1 "standard laboratory conditions of 22 ℃ ± 5 ℃" with the words "22 ℃ ± 2 ℃ of standard laboratory conditions. " For ease of use, and ISO 2971.1998 as compared to this section made the following editorial changes. --- Remove the ISO 2971.1998 Foreword; --- Modify the ISO 2971.1998 the name changed to "the determination of the physical properties of cigarettes and filter rods - Part 3. circumferential laser method." Appendix A of this section is normative appendix, Appendix B, Appendix C is informative appendix. This part by the State Tobacco Monopoly Bureau. This part of the National Standardization Technical Committee on Tobacco (SAC/TC144) centralized. This section drafted by. China Tobacco Standardization Research Center, Henan Tobacco Quality Supervision, Inspection Station, the State Tobacco Quality Supervision and Inspection center. The main drafters of this section.

1 Scope

This section GB/T 22838 provides for a non-contact, laser beam scanning to measure circular or elliptical cross-section of the shaft Circumferential surface of the average, maximum, minimum and a method ovality. This section applies to cigarettes and filter. Note 1. Pull the tape, optical measurement method and pneumatic technology is also widely used in cigarettes and filter rods Determination of nominal diameter. These measurements refer to Appendix C. Note 2. For those who use the diameter of the circumference as an indicator rather than a laboratory, may be converted to π multiplied by the diameter of the circumference value.

3 Terms and Definitions

The following terms and definitions apply to this part of the GB/T 22838 of. 3.1 According to the test method specified in this sample measured a minimum shape readings (like ≥100) the arithmetic mean. Note. The diameter of only approximately circular cross section as the rod-like sample parameters when effective. 3.2 Like a sample readings in the minimum. 3.3 Like a sample readings in the maximum. 3.4 A method for express rod-shaped sample of elliptical cross-section of the ellipse having. Note. The absolute arithmetic difference between the maximum ovality can and minimum diameters between readings obtained from the state. 3.5 Like readings from the calculated absolute arithmetic difference between the diameter and ovality ratio. Note 1. The relative ovality expressed as a percentage. Note 2. The opening will take the artificially produced in the calculation of the maximum diameter, should be absolute and relative ovality ovality note gum line (take the mouth) affect the quality of them, because Several high diameter readings. ......
