GB 5606 "Cigarettes" is divided into six parts.
- Part 1.Sampling;
- Part 2.Mark;
- Part 3.Technical requirements for packing, making, storage and transport;
- Part 4.Technical requirements for sense evaluation;
- Part 5.Mainstream smoke;
- Part 6.Quality evaluation.
This Part is Part 5 of GB 5606.

technical specification of cut tobacco".
The main changes of this Part, as compared with GB 5606.5-1996, are as follows.
- CANCEL the technical requirements and test methods for water-soluble total sugar,
total nitrogen, total alkaloids, ammoniacal alkali in cut tobacco;
- ADJUST the grades of tar content in the packet label;
- ADJUST the tolerance of tar content;
- ADJUST the tolerance of nicotine content in smoke;
- ADD the carbon monoxide content in smoke as an assessment indicator.
This Part was proposed by the State Tobacco Monopoly Administration.
This Part shall be under the jurisdiction of the National Tobacco Standardization
Technical Committee (TC 144).
The drafting organizations of this Part. State Tobacco Monopoly Administration,

GB/T 5606.1 Cigarettes - Part 1.Sampling
GB/T 19609 Cigarette - Determination of total and nicotine-free dry particulate
matter using a routine analytical smoking machine (GB/T 19609-2004, ISO
4387.2000, MOD)
YC/T 30 Cigarettes - Determination of carbon monoxide in the gas phase of smoke
- NDIR method
YC/T 156 Cigarettes - Determination of nicotine in smoke condensates - Gas-
chromatographic method (YC/T 156-2001, idt ISO 10315.2000)
3 Requirements
3.1 Tar content
3.1.1 The tar content grade and the corresponding packet indicated tar content are as
given in Table 1.
3.1.2 Tar content tolerance
4 Test method
4.1 Preparation of test sample
Take laboratory sample in accordance with GB/T 5606.1, to prepare test sample.
4.2 Tar content
It is determined in accordance with GB/T 19609.
4.3 Nicotine content in smoke
It is determined in accordance with YC/T 156.
Note. For the organization which does not adopt gas chromatographic method, it may follow
YC/T 36 to determine the total plant alkaloid in stead of nicotine, meanwhile make explanatory
note in the expression of results.
4.4 Carbon monoxide content in smoke
It is determined in accordance with YC/T 30.
5 Inspection rules
5.1 Mainstream smoke quality defects
Mainstream smoke quality defects of cigarettes are divided into categories A and B.
Among them, tar content is a category A quality defect item, whilst smoke nicotine
content and smoke carbon monoxide content are category B quality defects.
5.2 Tar content
5.2.1 If the measured tar content meets the requirements of 3.1, the score will be
calculated according to the packet indicated tar content. The low tar content level will
get 100 points, the medium tar content level will get 80 points, the high tar content level
will get zero point.
5.2.2 If the measured tar content does not meet the requirements of 3.1, the tar content
will get zero points, meanwhile, the lot of cigarettes will be judged as unqualified.
5.3 Nicotine content in smoke
If the measured nicotine content in smoke meets the requirements of 3.2, the nicotine
content in smoke will be scored 100 points; otherwise, zero points will be scored.
5.4 Carbon monoxide content in smoke
