Test summary


This part of the ISO 9727 standard concerns the force needed to extract a cylindrical cork from a wine bottle. Samples of cork stoppers are selected in accordance with ISO 2859-1, ISO 3951 and ISO 4707. After conditioning for 24 hours, the corks are fitted into filled wine bottles then stored horizontally for eight days, after which the maximum extraction force is measured.



Test apparatus


Force testing stand

Force gauge or loadcell compatible with the force testing stand

Apparatus for clamping the bottle vertically on the force testing stand

Corkscrew of defined dimensions



Preparation


Corks are conditioned prior to testing for 24 hours at 23 ± 2°C and 50 ± 5%. RH.



Test method


Fill clean bottles to the correct level with a 10% solution of ethanol, and insert the cork.

After five minutes lay the bottle horizontally and store for eight days at 20 ± 2° C and humidity of 65 ± 5% RH.

Insert the corkscrew into the cork stopper until 3 mm can be seen outside the stopper.

Clamp the bottle vertically onto the test stand, and connect the corkscrew to the load measuring cell.

Withdraw the cork at a speed of 30 cm per minute while recording the extraction force.

Record the maximum extraction force, and report in decanewtons (daN).
