    13、Bibliography16ISO 15592-1:2001(E) iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body

    14、interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotech

    15、nical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publi

    16、cation as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 15592 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such

    17、 patent rights. International Standard ISO 15592-1 was prepared by Technical Committee ISO/TC 126, Tobacco and tobacco products. ISO 15592 consists of the following parts, under the general title Fine-cut tobacco and smoking articles made from it Methods of sampling, conditioning and analysis: Part

    18、1: Sampling Part 2: Atmosphere for conditioning and testing Part 3: Determination of total particulate matter of smoking articles using a routine analytical smoking machine, preparation for the determination of water and nicotine and calculation of nicotine-free dry particulate matter Part 4: Classi

    19、fication of wrappers Part 5: Fine-cut tobacco to be used with specified wrappers Part 6: Effect of incorporation of loose filters Annexes A and B form a normative part of this part of ISO 15592. Annex C is for information only.ISO 15592-1:2001(E)v Introduction When this part of ISO 15592 was prepare

    20、d there were no existing national standards, rules, regulations or laws which had to be taken into account. However, experience with manufactured cigarettes suggests that two different procedures are required, as follows: sampling at the point of sale; sampling at the producersp re mi se so ri mp o

    21、rt e r s and distributors warehouses. The principle underlying all sampling procedures is to produce a sample representative of the whole. With manufactured cigarettes it is possible to sample from a number of sources and mix the sample before sub-sampling to produce a sample for testing. With fine-

    22、cut tobacco, this is not possible since mixing of the tobacco with very long, fine strands is ineffective and results in the degradation of the tobacco. Thus, if the analysis is to be performed on smoking articles made from tobacco, it is necessary to make smoking articles from all samples and then

    23、to mix the fine-cut smoking articles before sub-sampling. This may require sampling a large quantity of tobacco, and making a large number of smoking articles. Sophisticated sampling plans are often too expensive to be used. The two procedures in this part of ISO 15592 are both simple and reliable.

    24、Sampling is carried out either as a single procedure or as part of a series of samplings. Sampling is carried out “at one point in time“, for example tobacco available for distribution from a factory/warehouse or available at a retail outlet on the market on a particular day. When a sample is requir

    25、ed which represents fine-cut tobacco available over an appreciable period of time (e.g. fine-cut tobacco representing several months production) a number of sub-period samples will be taken at different times and the test results combined. The sampling plan depends upon the purpose of sampling (e.g.

    26、 determination of physical properties or of smoke constituents). Further background considerations on the choice of sampling procedures are given in an informative annex C. It concludes that determinations of smoke yield should be made on the population manufactured for sale, sampled at manufacturer

    27、s factories or importers warehouses. Annex A (normative) establishes procedures for sampling fine-cut tobacco which is intended to be made into fine- cut smoking articles for the determination of the mean values of total and nicotine-free dry particulate matter. Detailed sampling plans are given. An

    28、nex B (normative) establishes methods for sampling fine-cut tobacco which are intended for the determination of the mean values of parameters of fine-cut tobacco itself or the determination of mean values of parameters of fine- cut smoking articles made from the fine-cut tobacco.INTERNATIONAL STANDA

    30、It provides information on the statistical treatment of data and provides guidance based on practical experience of the order of ranking when a product is sampled in accordance with the specified procedures, in particular, when smoking articles are made from the sampled fine-cut tobacco and smoked f
