BS ISO 16420:2013 pdf free.Cork一Cork stoppers for still wines一Mechanical and physical specifications
For all parameters, this set of specifications comprises:
一a proposal for the number of stoppers to be tested (incremental sample);
一an acceptable quality level;
and, for certain parameters:
一nominal value or values;
一specification limits (or “tolerances”).
For cork stoppers for still wines, and for certain parameters, the concept of a range is introduced, with 3 decreasing levels of requirements:
一upper range;
一standard range;
一entry level.
It is, therefore, up to the consumer to specify, for each batch of cork stoppers ordered, what their needs are based on these three specification levels (or ranges).
It is also up to each supplier, besides a commercial reference for each batch of cork stoppers, to define which range applies in terms of the requirements in this International Standard.
The sampling method, as well as the possible repetitions of incremental samples are defined by the sampling standard (Ccurrently being drafted) or defined jointly by the consumer and the supplier.
The stoppers tested shall comply with the requirements of ISO 9727.

These values apply to tests carried out with glass cylindrical tubes.
NOTE For the same batch of stoppers, it is not possible to compare the extraction force test results obtained from cylindrical glass tubes with the results obtained from the necks of bottles.BS ISO 16420 pdf download.
