Crown finish for glass packaging: ISO standard published

18 October 2013

An international standard ISO 12821 has been published specifying the dimensions of the 26-mm-tall crown finish for glass bottles containing beverages. The standard contains a number of illustrations with dimensions and tolerances: shoulder and bore dimensions, profile of the finish, point “P” and glass sealing surface for which two alternatives are given. The document is based on CE.T.I.E datasheets.
This document was prepared as EN 14634:2010 and was adopted, under a special “fast-track procedure”, by ISO/TC 63, Glass containers, in parallel with its approval by the ISO member bodies (World Packaging Standardisation Newsletter, October 2013).
