Overview
ISO 9100-14:2005 is an international standard developed by the International Organization for Standardization (ISO) that specifies the precise dimensions for vacuum lug finishes with a nominal size of 110 mm regular. These finishes are designed for wide-mouth glass containers, ensuring compatibility and uniformity in sealing systems used for vacuum packaging. This standard represents Part 14 of the ISO 9100 series, which covers a range of vacuum lug finish types used in glass container closures.
Adhering to ISO 9100-14:2005 ensures consistent manufacturing quality, optimal sealing performance, and reliable vacuum closures, which are critical in preserving product integrity during distribution and storage.
Key Topics
-
Scope and Application
ISO 9100-14:2005 applies explicitly to vacuum lug finishes with a nominal dimension of 110 mm regular, tailored for wide-mouth glass containers. It provides detailed dimensional specifications required for the design and manufacture of these finishes.
-
Dimensional Specifications
The standard precisely defines key dimensions such as diameter E, T, and C, thread profiles, pitch, and angles involved in the thread construction. It mandates angular tolerances and concentricity requirements to maintain functional integrity. These include:
- Profile and cut angles for the thread finishing tools
- Thread pitch and number of threads per inch (TPI)
- Surface requirements for sealing zones to prevent defects that could compromise vacuum integrity
-
Quality Requirements
ISO 9100-14 emphasizes the importance of smooth, defect-free sealing surfaces without cracks or irregularities and minimal ovalization of lugs to ensure tight, secure vacuum closures. It also references general tolerances for dimensions per EN 22768-1 for borderline tolerances not explicitly detailed in the standard.
-
Collaboration and Compliance
Developed under cooperation between ISO/TC 63 (Glass Containers Technical Committee) and the European Committee for Standardization (CEN), this standard aligns with European packaging standards and is harmonized with related CEN documents. It supersedes the earlier ISO 9100:1992 edition.
Applications
-
Packaging Industry
ISO 9100-14:2005 is essential for manufacturers of glass packaging products, especially those producing containers that require vacuum sealing to protect contents such as food, beverages, pharmaceuticals, and chemical products.
-
Glass Container Manufacturing
The standard guides glass container producers on mechanical design parameters to ensure compatibility with closure systems, enhancing mass production efficiency and interchangeability of parts.
-
Closure System Design
Developers of vacuum lug caps use these dimensions to design complementary sealing components that provide airtight sealing, critical in extending shelf life and maintaining product safety.
-
Quality Assurance and Compliance
Companies implementing this standard can assure customers and regulatory agencies of their products' compliance with international norms, facilitating smoother market acceptance and reducing technical disputes.
