Cork. Cork stoppers for still wine. Sampling plan for the quality control of cork stoppers
This International Standard describes the quality control sampling plans for the receipt and 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 available. 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 ISOÂ 9727 (all parts)];
chemical tests: analysis of oxidizing residues (see ISOÂ 21128);
microbiological tests: enumeration of colony-forming units of yeasts, moulds, and bacteria capable of growth in an alcoholic medium (see ISOÂ 10718);
sensory analysis (see ISOÂ 22308);
the analysis of releasable 2, 4, 6-trichloroanisole (TCA) (see ISOÂ 20752).
Type tests and validation tests are not included in this International Standard (for example global migration).
