7、iso.orgPublished in SwitzerlandBS ISO 16419:2013ISO 16419:2013(E)ForewordISO (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 co
8、mmittees. Each member body 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 th
9、e International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft Internation
10、al Standards adopted by the technical committees are circulated to the member bodies for voting. Publication 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 document may be the

12、s International Standard applies to both semi-elaborated natural cork stoppers and colmated natural cork stoppers at the definitive dimensions stage, and finished natural cork stoppers and colmated natural cork stoppers ready to use.It describes the anomalies of cork stoppers that can be detected by
13、 visual examination of the manufacturer or the end-user.These anomalies, according to their size, can have functional or not functional consequences being able to alter, more or less, the cork stoppers sealing capacity.On the basis of a common sampling example, this International Standard proposes f
14、or all these anomalies some specifications for stoppers.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest
15、edition of the referenced document (including any amendments) applies.ISO 633, Cork Vocabulary3 Designation for the different requirement levelsFor natural cork stoppers for still wines, the following notion of range with three decreasing levels of requirement is introduced: superior range; standard
16、 range; entry of range.Besides the commercial reference of the lot of cork stoppers, it belongs to the end-user to clarify what are his/her needs in relation to these three specifications (or range) levels, and to the manufacturer to define to which range the lot of cork stoppers belongs.The definit
17、e ranges do not necessarily include the total amount of usable cork stoppers for sealing; there can also be other unanimous transactions that are out of the scope of this International Standard.4 List of anomalies taken into accountOnly the following will be considered cork stoppers anomalies: longi

19、ol bumps, gutters); belly.Other aspect irregularities are not considered as anomalies since they only affect the cork stoppers presentation and will be taken into account in the cork stoppers visual classification.In the case of having more than one anomaly with functional consequence in the same co
20、rk stopper, only the most important will be considered (penalized).5 Anomalies of natural corkwood stoppers and colmated natural cork stoppers for still winesBoth Table 1 and Table 2 present the anomalies in relation to the raw material and to the fabrication process respectively, being: columns 1 a
21、nd 2 The name and definition of the anomaly in accordance with ISO 633 (Vocabulary). columns 3 and 4 The threshold relates to the size and/or the position of the anomaly to be considered in order to assess whether it is likely to have a functional or not functional consequence (if the threshold is n
22、ot reached, the observed visual irregularity does not count as an anomaly). columns 5, 6, and 7 The acceptance quality limit (AQL) specifications according to the cork stoppers range.These tables are considered for a working sample of 80 selected cork stoppers, which are considered a representative
23、sample of a lot.This value, which is given as an example, corresponds to day-to-day practices in the enterprises.2 ISO 2013 All rights reservedBS ISO 16419:2013ISO 16419:2013(E)Table1 Anomalies of raw materialName of the anomalyAnomalydefinition(given in ISO633)Potentialfunctionalconsequencethreshol
