9、de 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 interested in a subject for which a technical committee has been established has the right to be represented on tha
10、t committee. International organizations, 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.International Standards are drafted in ac
11、cordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requ
12、ires 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 document may be the subject of patent rights.

14、nd shipping of ready-to-use, cylindrical stoppers (flush with cork mouth finish) in semi-worked or finished cork used for still wines.These plans do not apply to controls made during production.This sampling plan applies to the following parameters, for which a standardized analysis method is availa
15、ble. These are the parameters which are applicable to: physical tests: dimensions, mass, and apparent density for agglomerate cork stoppers, moisture content, dimensional recovery after compression, extraction force, liquid tightness, and dust content see ISO 9727 (all parts); chemical tests: analys
16、is of oxidizing residues (see ISO 21128); microbiological tests: enumeration of colony-forming units of yeasts, moulds, and bacteria capable of growth in an alcoholic medium (see ISO 10718); sensory analysis (see ISO 22308); the analysis of releasable 2, 4, 6-trichloroanisole (TCA) (see ISO 20752).T
17、ype tests and validation tests are not included in this International Standard (for example global migration).2 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.2.1outer packagingcardboard box that contains bags of stoppers2.2packagingplastic bag that
18、 contains the stoppers3 Initial sampling of the batchThe definition of a batch will vary according to the supplier, who will define this concept such that a group of stoppers is as homogeneous as possible for the characteristics evaluated.An initial sample of n stoppers will be taken from a batch of
19、 N stoppers.The quantity n of stoppers to be sampled will be the optimum amount of stoppers necessary to perform the controls: stoppers used in non-destructive tests can be reused. Controls shall be carried out in a logical order, according to this optimization criterion. ISO 2012 All rights reserve
20、d 1BS ISO 17727:2012ISO 17727:2012(E)Take a sufficient quantity so as not to have to repeat the sampling in the event that the test shall be repeated.a) For stoppers packaged in bags that are repackaged in cardboard boxes: number of boxes constituting a batch = K; sample size (for analysis) = n stop
21、pers; number of boxes to be opened: k = K ; the sampling shall be taken from k boxes with n/k stoppers per box; take stoppers from a single pack of each box opened.b) For stoppers directly packaged in large bags: number of bags constituting a batch = K; sample size (for analysis) = n stoppers; numbe
22、r of bags to be opened: k = K ; the sampling shall be taken from k bags with n/k stoppers per bag.4 Sampling implementationFor microbiological analysis (see ISO 10718), the sampling shall take place under specific hygiene conditions. The list of characteristics that follow a normal random distributi
23、on includes the “Checking visual appearance compliance and anomaly count” test. This visual check shall be done first, in order to eliminate stoppers with defects.5 Sampling of stoppers for each test5.1 GeneralThe different parameters to be tested for the stoppers shall be treated by differentiating
24、 those following a normal distribution and those following a random distribution.5.2 Normal distribution parametersThis affects the following parameters: dimensions; density (for agglomerate cork stoppers); moisture content; dimensional recovery; extraction force; liquid tightness; dust content; per
