CETIE Guide 3 (FR)
CETIE Guide 3 FR is a specialized testing guideline used in the wine and spirits industry to evaluate the torque required to break the tamper-evident ring or security band of screw-cap closures during the first opening. Tamper-evident closure technology is common on wine and spirits products and other higher-quality drinks to help ensure product authenticity and to provide a visual tamper-evident signal. The guide establishes a standardized procedure for measuring the bridge break torque, helping manufacturers verify that closure systems function correctly while maintaining consumer convenience. Presto offers precision torque testing solutions that support accurate and repeatable testing of tamper-evident closures in accordance with CETIE Guide 3 FR requirements.
Significance The effectiveness of a tamper-evident band is essential for product protection and customer experience. Inadequate bridges between the band and closure can cause breakage during filling, transportation, and handling. If they are too strong, excessive force may be required during opening, creating difficulties for consumers. CETIE Guide 3 FR helps manufacturers assess the balance between tamper evidence and opening comfort by measuring the torque required to separate the security band from the closure. The resulting data supports closure design validation, process control, quality assurance, and production consistency. This testing is particularly important for premium wine and spirit packaging, where closure performance contributes directly to brand reputation and customer satisfaction. Scope CETIE Guide 3 FR covers the determination of bridge break torque for tamper-evident screw-cap closures used on bottles and containers. The method is applicable to metal and plastic closure systems equipped with security bands or breakable bridges. Test results support product development, packaging validation, supplier qualification, and routine quality control. Presto’s torque testing instruments deliver accurate and repeatable measurements that help manufacturers maintain closure integrity and packaging quality.
