Overview
ISO 9100-6:2005 is an international standard that specifies the exact dimensions for vacuum lug finishes with nominal sizes of 53 mm and 58 mm regular, designed specifically for wide-mouth glass containers. This standard is part of the broader ISO 9100 series, which covers various sizes of vacuum lug finishes used in glass packaging. The standardized dimensions ensure compatibility, functionality, and quality in vacuum sealing applications for glass containers, which are crucial for product preservation and safety.
Developed by ISO/TC 63 (Glass Containers) in cooperation with the European Committee for Standardization (CEN), ISO 9100-6:2005 supersedes the earlier ISO 9100:1992 and aligns with European technical specifications. It defines critical parameters such as thread profiles, pitch, angles, and tolerances to guarantee proper sealing and reliable vacuum closure.
Key Topics
- Vacuum Lug Finishes: Detailed specifications for vacuum lug finishes at 53 mm and 58 mm regular sizes, which are commonly used in wide-mouth glass containers.
- Dimensional Accuracy: Precise dimensions, including diameter, thread pitch, angle, and height, are provided to ensure part interchangeability and correct sealing.
- Thread Construction: Descriptions and illustrations of thread profiles and technical parameters such as thread angle (α), thread pitch, and number of threads per inch (TPI).
- Design Requirements: Guidelines on surface finish quality, including absence of asperities, cracks, or defects that could compromise the sealing function.
- Concentricity and Ovalization: Recommendations to minimize ovalization of the lug finish and ensure concentric diameters for optimal performance.
- Tolerance Standards: Reference to general tolerance requirements following EN 22768-1 for linear and angular dimensions.
- Compatibility and Opening: Specifications to facilitate correct opening of vacuum caps by defining theoretical break points and clearance zones.
Applications
ISO 9100-6:2005 is essential for manufacturers, designers, and quality controllers involved in the production and use of glass containers with vacuum lug finishes. Practical applications include:
- Food and Beverage Packaging: Ensuring glass jars and wide-mouth containers used for jams, sauces, and beverages maintain vacuum integrity for product freshness.
- Pharmaceuticals and Cosmetics: Guaranteeing sealed glass containers meet strict packaging requirements for safety and contamination prevention.
- Packaging Design and Engineering: Providing precise dimensional data for tooling and mold construction to manufacture compliant lug finishes.
- Quality Assurance: Enabling standardized inspection criteria for vacuum lug finishes in glass container manufacturing.
- Supply Chain Coordination: Facilitating interchangeability of components by manufacturers and packagers across international markets.
Related Standards
ISO 9100-6:2005 is part of the wider ISO 9100 series addressing vacuum lug finishes on glass containers. It complements other parts including:
- ISO 9100-1: General requirements for vacuum lug finishes.
- ISO 9100-2 to ISO 9100-14: Specifications for other nominal sizes (e.g., 33 mm, 38 mm, 43 mm, up to 110 mm), both regular and deep versions.
- EN 22768-1: General tolerances for linear and angular dimensions, critical for manufacturing precision.
- ISO 2768-1:1989: Reference for general dimensional tolerances in engineering drawings.
By adhering to ISO 9100-6:2005 and related standards, industries can achieve consistent product quality, regulatory compliance, and enhanced customer satisfaction in vacuum-sealed glass packaging solutions.
