<p>ISO 17727:2012 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.</p>
<p>These sampling plans apply to the following parameters, for which a standardized analysis method is available. These are the parameters which are applicable to:</p>
<ul>
<li>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);</li>
<li>chemical tests: analysis of oxidizing residues (see ISO 21128);</li>
<li>microbiological tests: enumeration of colony-forming units of yeasts, moulds and bacteria capable of growth in an alcoholic medium (see ISO 10718);</li>
<li>sensory analysis (see ISO 22308);</li>
<li>the analysis of releasable 2, 4, 6-trichloroanisole (TCA) (see ISO 20752).</li>
</ul>
