This section GB/T 22838 Part 16.

The partial modification using ISO 3550-1:1997 "Determination of loss of tobacco from cigarette ends - Part 1. Rotating cage Law" (in English).

Taking into account the development and application of measurement techniques Cigarette computer processing technology, employing ISO 3550-1:1997 when this part made some modify. About the technical differences have been incorporated into the body and they are involved in terms of the margin of a single vertical line identification. Appendix D We are given a list of these technical differences and the reasons for the reference.

For ease of use and references to ISO 3550-1:1997 This section also made the following editorial changes.

--- The "ISO 3550-1:1997 to the present part" to "GB/T 22838 in this section";

--- This part of the formula are numbered.

Appendix A of this section is normative appendix, Appendix B, Appendix C and Appendix D is an informative annex.

After testing Cheng, the cage rotating about its horizontal central axis and roll cigarettes are in a cage. Determination of the amount of exposed tobacco cigarette ends from falling.

The test conditions and the shape and size of the cage, and the pitch diameter of the shaft, the rotational speed of the cage, and the number of rotations of each test cigarette by the the number of cigarettes each test given diameter about.

First measurement sample falling tobacco mass m1 L. According to the physical dimensions of the quality and testing of cigarettes to determine the amount of each doff exposed end and the exposed end of each unit area doff amount.
