NFB 57 100
The French standard NF B57-100 consists of test methods and performance requirements for cork stoppers used for the packaging of wines and other beverages. The standard is based on testing mechanical characteristics of cork closures to ensure they are adequate for sealing the bottles while in storage, in transit, and during the use of the product. For cork stoppers, the sealing performances should be maintained while the cork stoppers are able to withstand insertion, extraction, and handling forces without damage. NF B57-100 specifies standard methods for measuring important characteristics that affect closure integrity and long-package performance. To support their NF B57-100 requirements, Presto provides advanced force and torque testing solutions to enable manufacturers to accurately assess the performance of their cork stoppers.
Significance
Cork stoppers are one of the key elements in product protection to ensure product quality, avoid leakage, and maintain the sensory qualities of wines and other bottled beverages. Mechanical characteristics like pull, compression, and structural integrity have a direct impact on bottling efficiency and consumer experience. NF B57-100 is used by cork manufacturers to confirm that their corks meet a given set of performance specifications and ensure that cork sealing characteristics are consistent throughout the product life cycle. The test results are used for quality assurance, supplier qualification, product development, and manufacturing process control. Testing ensures lower rates of packaging failure and contributes to brand reputation in very competitive beverage markets. Scope NFB57-100 covers the evaluation of mechanical and functional properties of cork stoppers used in beverage packaging. The standard covers the natural cork, the agglomerated cork, and technical cork closures used for bottling applications. Testing might involve compression, extraction, retention, and other performance measurements that impact closure function. Data obtained can be applied for quality management, product comparisons, process validation, and packaging development. Presto's testing equipment ensures accurate and repeatable data that helps the manufacturers ensure that cork stopper performance is correct and compliant with industry quality standards.
