ISO 9727-2
ISO 9727-2 is an international standard that has been published by the International Organization for Standardization (ISO) under Technical Committee ISO/TC 87. It sets out a test method for the mass of cylindrical cork stoppers, including ready cork stoppers, ready-to-use semi-worked, and totally or partially made of agglomerated cork stoppers, and for the calculation of their apparent density. This standard is part of the ISO 9727 family of physical testing of cork stoppers and is an essential part of quality control in the bottling and packaging industries, which Presto's precision testing devices serve with wide-ranging support.
Significance
The mass and apparent density of cork stoppers in their agglomerated form are important quality characteristics that have a direct impact on sealing properties, consistency, and product integrity. These properties can vary, resulting in poor closure, a compromise of product safety, and product shelf life. Manufacturers can use ISO 9727-2 to objectively measure cork quality, helping to make more effective purchasing decisions and better quality control during the manufacturing process. This standard is also referred to in ISO 17727 and ISO 16420, which is proof of its use in the general framework of cork stopper quality. Scope This part of ISO 9727 gives test methods for the mass of cylindrical cork stoppers, ready-to-use or semi-worked, wholly or partly made of agglomerated cork, and for the calculation of the apparent density of stoppers made of agglomerated cork only. The precision weighing and physical testing equipment offered by Presto enables cork stopper manufacturers and bottlers to ensure that they accurately measure according to this standard, adhere to their quality benchmarks, and comply with the global standard with confidence.
