BS ISO 10106:2018,Cork stoppers – Determination of global migration.BS ISO 10106:2018 pdf download for free here.
ISO 10106:2018 specifies a test method to measure the global migration of cork stoppers. This includes all kind of cork stoppers (completely or partially inserted in the bottle neck).
ISO 10106:2018 is applicable to all types of cork stoppers that are ready to use, simulating the real conditie.
A bottle with an adequate finish is used to carry out the test.
4 Principle
Introduction of the cork stopper in the neck of a bottle containing the appropriate simulator. The contact cork stopper/simulator is carried out in specific conditions of time and temperature. After evaporation of the obtained solution, the global mass transferred to the simulator from the cork stopper is determined, by weighing.
8.2 Contact with the simulator
Fill up nine bottles (5.2.1),each with 100 ml of simulator and cork them with a corking machine (6.1).
Assure that the corking process is done correctly, accordingly to the type of cork stopper and normal use condition.
Leave the simulator to settle for 60 min in the upright bottles, assuring that nothing modifies the contact surface between the cork stopper and the simulant.
Then, turn the bottles upside down and leave them in this position for 10 days, at the temperature specified in 8.1.
8.4 Blank test
At the same time, carry out a blank determination, by replacing the “cork stopper/bottle” pair with a “watch glass/bottle “pair (see 5.2.3),keeping the three bottles in a vertical position, head down, during the 10 days testing period.
