Cylindrical cork stoppers - Physical tests - Part 8: Determination of capillaritystandard by International Organization for Standardization, 04/01/2022
standard by International Organization for Standardization, 04/01/2022
This document specifies the test method to determine the capillarity of cylindrical cork stoppers. It consists in measuring the capillary rise by dipping in a hydro-alcoholic solution containing a dye. Two methods using the same procedure but different concentrations of hydro-alcoholic solutions are described.
It is applicable to all types of cylindrical cork stoppers, ready for use.
