oSIST prEN 16287:2011

Overview

oSIST prEN 16287:2011 is a draft European standard developed by the Slovenski inštitut za standardizacijo (SIST), under the responsibility of Technical Committee CEN/TC 261 “Packaging”. This document focuses on glass packaging, specifically outlining the dimensional standards for 28 millimetre screw finishes-designated as MCA 1-on glass containers intended for pressure capsules. These finishes are commonly used to ensure safe sealing and closure for beverages and other products stored under pressure or vacuum.

By standardizing these screw finishes, the document facilitates reliable sealing, compatibility with tamper-evident closures, and improved safety in packaging for pressurized or vacuum-sealed liquids.

Key Topics

• Screw finishes for glass containers: The standard specifies precise measurements for the 28 mm MCA 1 finish, which is crucial for sealing efficiency and package integrity.
• Pressure capsule compatibility: Designed for use with closures that can withstand the internal pressure of carbonated or vacuum-sealed products.
• Tamper-evident closures: Recommends compatibility with both metal and plastic tamper-evident caps, ensuring consumer safety and product integrity.
• Quality and consistency in manufacturing: Provides glass manufacturers with clear criteria for thread pitch, diameter tolerances, sealing surface requirements, and mould parting lines.
• International harmonization: Enables broad interoperability between glass packaging producers, closure manufacturers, and filling lines across different countries.

Applications

The MCA 1 screw finish plays a vital role in several industry sectors where reliable pressure-resistant glass packaging is essential. Practical applications include:

• Bottling of carbonated beverages: Widely used for soft drinks, sparkling water, and other carbonated beverages requiring pressure-tight seals.
• Vacuum-sealed liquids: Suitable for packaging juices, sauces, and similar products that benefit from vacuum sealing for extended shelf life.
• Food and beverage manufacturing: Provides bottlers and glass manufacturers with standardized dimensions for cap compatibility and automated filling operations.
• Packaging safety and sustainability: Supports the use of tamper-evident closures, helping prevent contamination, pilferage, or accidental opening during transport and handling.

By adopting standardized MCA 1 finishes, manufacturers and filling lines benefit from reduced risks of leakage, spoilage, and customer complaints, while consumers enjoy improved product safety.

Related Standards

To support effective implementation and integration, oSIST prEN 16287:2011 references related international standards and guidelines:

• CE.T.I.E. GME 32-05: The foundational data sheet used for the development of this standard, offering technical insights into the MCA 1 finish.
• EN and prEN standards on bottles and closures: Other documents within the CEN / TC 261 portfolio address topics such as testing methods, material specifications, and quality assurance for glass packaging.
• ICS 55.100: The International Classification for Standards category for bottles, pots, and jars highlights the relevance for glass container manufacturing.

Standardization in glass packaging screw finishes streamlines international commerce, optimizes production efficiencies, and guarantees a high level of product protection for pressure-sensitive applications.
