GB 5606.5-1996
This standard is a revision of GB5608-85 cigarette cut tobacco. In terms of writing format, it was changed from the original independent standard to GB5606.5 Cigarette mainstream smoke and cut tobacco chemical technical indicators. And the following revisions were made in terms of technical content: the combustibility and dust content of cigarettes were classified as GB5606.3-1996 technical requirements for cigarette rolling. The tar content was refined into five grades, the tolerance of tar content on the box label was specified, and the scores for each tar content grade were specified. The technical requirements and test methods for the sugar-alkali ratio of cigarettes were cancelled, and the technical requirements and test methods for the main chemical components of cut tobacco were added. The technical requirements, test methods and inspection rules for the nicotine content of smoke were added. The technical requirements and test methods for carbon monoxide in smoke were added. This series of standards includes:

Approved by the State Administration of Technical Supervision on April 17, 1996, and implemented on January 1, 1997. GB 5606.5-1996. 3.3 The grades of flue gas carbon monoxide and the corresponding carbon monoxide content are shown in Table 2. Table 2 The grades of flue gas carbon monoxide and the corresponding carbon monoxide content Carbon monoxide grade Carbon monoxide, mg 3.4 Main chemical components of cut tobacco 15. 0～≤20. 0 The water-soluble total sugar, total nitrogen and total alkaloid content of cut tobacco should remain stable, and the ammoniacal alkali content should be as low as possible. 4 Sampling According to GB/T5606.1, laboratory samples are taken and test specimens are prepared. 5 Test methods 5.1 Tar content According to YC/T29.
5.2 Nicotine content in smoke
Determine according to YC/T0008.
Note: If the unit of gas chromatography is not used, the total alkaloid content can be determined according to YC/T 36 instead of nicotine, and an annotation shall be made in the presentation of the result. 5.3 Carbon monoxide content in smoke
Determine according to YC/T30.
5.4 Main chemical components of cut tobacco
5.4.1 Prepare the sample according to YC/T31 and determine the moisture content. 5.4.2 Determine the total water-soluble sugar content according to YC/T32, and 5.4.3 Determine the total content according to YC/T33.
5.4.4 Determine the total alkaloid content according to YC/T34. 5.4.5 Determine the total volatile alkaloid content according to YC/T35. The ammoniacal alkaloid content is the total volatile alkaloid content minus the total alkaloid content in ammonia. 6 Inspection rules
6.1 Smoke tar content
If the measured tar content does not meet the requirements of 3.1.2, the batch of cigarettes is judged to be unqualified. If the measured tar content meets the requirements of 3.1.3, the score will be given according to the tar content level on the box label; otherwise, 0 points will be given. The low tar content level will get 100 points, the medium-low tar content level will get 90 points, the medium tar content level will get 70 points, the medium-high tar content level will get 50 points, and the high tar content level will get 0 points.
6.2 Smoke nicotine content
If the measured nicotine content in the smoke meets the requirements of 3.2, 100 points will be given, otherwise 0 points will be given. 7 Marking
The packaging body should be marked with warnings, tar content, and smoke nicotine content. The marking should meet the requirements of GB/T5606.2. 334
