ISO 9100-12:2005

Overview

ISO 9100-12:2005 is an international standard developed by ISO (International Organization for Standardization) that specifies the precise dimensions for vacuum lug finishes of glass containers, specifically for the 89 mm regular nominal size wide-mouth glass containers. This standard ensures uniformity, quality, and compatibility in the manufacturing and use of vacuum lug finishes designed to create airtight seals on glass containers.

The standard is part 12 in the ISO 9100 series which comprehensively covers various sizes and types of vacuum lug finishes for glass containers. Maintaining consistent dimensions and design parameters ensures optimal sealing performance and safe packaging of contents in the food, beverage, pharmaceutical, and cosmetic industries.

Key Topics

• Dimension Specifications: ISO 9100-12:2005 defines critical measurements such as diameter sizes, thread pitch, cutter profile, and thread angles to standardize the 89 mm vacuum lug finish.
• Design Details: The finish includes features like cutter inclination angles, thread construction, and sealing surface quality to ensure proper functionality and tight vacuum sealing.
• Quality Requirements: Emphasizes minimal ovality in finish diameters and defect-free sealing surfaces to prevent leakage or loss of vacuum.
• Compatibility and Tolerances: The standard refers to general tolerances (e.g., EN 22768-1) for linear and angular dimensions to maintain manufacturing precision.
• Interoperability: Designed in cooperation with European standardization bodies (CEN) and aligns with related ISO parts to maintain cross-region compatibility.

Applications

The ISO 9100-12:2005 glass container vacuum lug finish standard is widely applied in sectors that depend on airtight sealing for product safety and longevity:

• Food and Beverage Industry: For wide-mouth glass jars and containers used to package pickles, sauces, preserves, and other vacuum-sealed products.
• Pharmaceutical Packaging: Ensures secure sealing for medicines or sensitive formulations stored in glass containers to prevent contamination and preserve efficacy.
• Cosmetics and Personal Care: Utilized in containers for creams, lotions, and other products requiring vacuum sealing for preservation and freshness.
• Packaging Manufacturing: Enables glass container makers and closure manufacturers to meet international quality standards and facilitate global trade.
• Supply Chain Assurance: Guarantees consistency in container finish dimensions, allowing seamless integration between glass container production and closure systems.

Related Standards

ISO 9100-12:2005 is part of the broader ISO 9100 series addressing vacuum lug finishes on glass containers, including:

• Part 1: General requirements for vacuum lug finishes
• Part 2 to Part 14: Various nominal sizes ranging from 33 mm to 110 mm (e.g., 33 medium, 38 regular, 77 regular, 100 regular, 110 regular)
• EN 22768-1: Provides general tolerances for linear and angular dimensions commonly referenced in ISO 9100-12 manufacturing processes.
• CETIE GME 20-10: An industry datasheet that contributed to the standard’s specifications for vacuum lug finishes.

This interconnected set of standards ensures a cohesive global framework for the design, production, and application of vacuum lug finishes on glass containers, facilitating quality assurance and industry consistency worldwide.
