适用范围：This International Standard specifies a method of obtaining a representative sample from a lot of paper or board, including solid and corrugated fibreboard (see ISO 4046), for testing to determine whether or not its average quality complies with set specifications.It defines the conditions which apply when sampling is carried out to resolve disputes between buyer and seller relating to a defined lot of paper or board, which has been or is being delivered. If less than 50 % of the lot is available for sampling, then sampling in terms of this International Standard will be invalid in the absence of agreement to the contrary.The method is unsuitable for determining the variability within a lot.In cases where International Standards make reference to sampling according to this standard but where such sampling is impossible, impractical or inappropriate, and where no dispute is involved, guidance is given in normative annex A.NOTE 2 Information on the preparation of test pieces is given in the appropriate International Standards.
