Specifies 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.

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 ISO9727 (all parts)];

• chemical tests: analysis of oxidizing residues (see ISO21128);

• microbiological tests: enumeration of colony-forming units of yeasts, moulds, and bacteria capable of growth in an alcoholic medium (see ISO10718);

• sensory analysis (see ISO22308);

• the analysis of releasable 2, 4, 6-trichloroanisole (TCA) (see ISO20752).

Type tests and validation tests are not included in this International Standard (for example global migration).
