Esch member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International or
4、ganizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are

10、: Sampling 1 Scope This part of ISO 11093, based on ISO 186:1994, Paper and board - Sampling to determine average quality, specifies a method for obtaining a representative Sample of a lot of cores for test purposes. NOTE 1 If less than 50 % of the tot is available for sampling, then sampling will b
11、e invalid in the absence of agreement to the contrary. 2 Definitions For the purposes of this part of ISO 11093, the following definitions apply. 2.1 lot: Aggregate of cores of a Single kind possessing specified characteristics. A lot may comprise one or more identical packaged units. 2.2 specimen:
12、Complete undamaged core taken from a packaged unit. 2.3 Sample: Aggregate of all specimens. 2.4 test piece: Complete core or a core section on which testing is carried out in accordance with the stipulations of the method of test. 2.5 selected at random: Taken in such a manner that each part of the
13、lot has an equal Chance of being selected. 3 Principle A selection of cores is taken at random from packaged units taken at random from the Pot. These are then subdivided and mixed so as to obtain from the specimens, the Sample from which the test pieces will be taken. 4 Procedure Take the specimens
14、 at random, their number as given in table 1. Table 1 - Number of specimens r Number of cores I Number of specimens I up to 99 I 5 I 100 to 499 I 10 I 500 and more 20 5 Additional requirements 5.1 Precautions Spetimens and test pieces shall be protected from harmful influences, for example direct su
15、nlight, considerable climatic fluctuations, liquids, etc. 5.2 Marking Spetimens and test pieces shall be provided with markings adequate to ensure that each specimen and test piece tan be identified beyond all doubt. These identification markings shall be indelible. They may be limited to the number
16、 of the sampling report and the Samplers signature. 5.3 Re-sampling If, as a result of an accident during sampling or testing, re-sampling is necessary, a new Sample shall be taken in accordance with the aforementioned specifications. Unless otherwise specified, samples may be taken from the same pa
17、ckaged units as before. lf re-sampling is deemed necessary for other reasons, it shall not be made from the Same packaged units. 1 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/26/2007
