EN ISO 9100-12:2005

Overview

EN ISO 9100-12:2005 is a European and international standard that specifies the dimensions of vacuum lug finishes for wide-mouth glass containers with a nominal size of 89 mm regular. Developed by CEN in collaboration with ISO Technical Committee TC 63, this standard ensures uniformity in vacuum lug finishes-critical components that help secure vacuum seals on glass bottles, jars, and other containers used across food, beverage, and pharmaceutical industries.

By defining precise dimensional requirements, EN ISO 9100-12:2005 facilitates consistent manufacturing and compatibility of closures, optimizing packaging safety and integrity to prevent spoilage or contamination. This standard supports efficient packaging processes and aligns with international tolerances to encourage global trade and compliance.

Key Topics

• Scope and Application
  Specifies dimensions for vacuum lug finishes with a nominal diameter of 89 mm designed for wide-mouth glass containers. It defines the profile of the finish to ensure secure vacuum sealing and closure functionality.

• Dimensional Specifications
  The standard provides detailed measurements, including main diameters (E, T, C), pitch, thread leads, and cutter profiles necessary for manufacture.

• Finish Characteristics
  Critical quality features such as surface smoothness of sealing areas-free from checks, crizzles, or defects-are outlined to guarantee proper sealing performance.

• Thread Design Parameters
  Includes thread angle (approximately 5°19') and pitch (25.4 mm or 1 T.P.I.), maintaining consistency for compatibility with standard closures.

• Manufacturing and Tolerances
  References general tolerances according to EN 22768-1 for linear and angular dimensions to ensure precision during production.

• Figures and Tables
  Illustrative diagrams and tables detail the finish’s cutter profile, thread construction, and sealing surface cross-sections for visual reference during design and quality inspection.

Applications

• Glass Packaging Industry
  Ensures glass container manufacturers produce vacuum lug finishes with consistent geometry, facilitating the use of standardized vacuum closure systems.

• Food and Beverage Packaging
  Supports the safe packaging of products requiring vacuum sealing such as jars and bottles for preserves, sauces, alcoholic beverages, and pharmaceuticals.

• Quality Control and Inspection
  Provides guidelines for verifying finish dimensions and surface quality during production runs, minimizing product loss due to improper sealing.

• Supply Chain Compatibility
  Promotes interoperability between container and closure suppliers worldwide, streamlining design exchange and reducing manufacturing errors.

• Research and Development
  Serves as a basis for developing new wide-mouth glass containers with vacuum sealing capabilities according to recognized international standards.
