标准范围

ISO 8243:2006规定了两种提供为销售而制造的卷烟群体的代表性样品的方法。根据取样是在销售点还是在工厂进行，规定了不同的程序。在一个时间点取样提供了在该时间点对香烟的所选特性的评价。取样在尽可能短的时间内进行。一段时间内的取样提供了持续的评估。出于实际目的，它可以被认为是在一个时间点采集的一系列样本。ISO 8243:2006提供了关于数据处理的统计基础的信息，并根据实践经验给出了NFDPM、尼古丁和CO产率的典型置信区间的估计值，当根据本国际标准对产品进行取样并按照国际标准ISO 3308、ISO 3402、ISO 4387、ISO 8中规定的程序进行熏制时，可能会发现NFDPM、尼古丁和CO产率的典型置信区间454、ISO 10315、ISO 10362-1和ISO 10362-2。

ISO 8243:2006 specifies two methods of providing representative samples of a population of cigarettes manufactured for sale. Different procedures are specified according to whether sampling is undertaken at the point of sale or at a factory.

• Sampling at one point in time provides for appraisal of the chosen properties of the cigarettes on that occasion. Sampling is carried out within as short a period as possible.
• Sampling over a period of time provides for on-going appraisals. It can be considered for practical purposes as a series of samples each taken at one point in time.

ISO 8243:2006 provides information on the statistical basis for the treatment of data and gives estimates, based on practical experience, of the typical confidence intervals for NFDPM, nicotine and CO yields which may be found when a product is sampled in accordance with this International Standard and smoked in accordance with the procedures specified in International Standards ISO 3308, ISO 3402, ISO 4387, ISO 8454, ISO 10315, ISO 10362-1 and ISO 10362-2.
