Overview
ISO 9100-13:2005 specifies the design and dimensional requirements for a vacuum lug finish with a nominal size of 100 mm regular, intended for wide-mouth glass containers. Part 13 is one element of the ISO 9100 series covering vacuum lug finishes and was prepared in collaboration between CEN and ISO/TC 63. The document sets out the required profiles, thread construction and references the figures and table that define the actual dimensions and cutter geometry.
Key reference elements in the standard include:
- Figures 1–3 (cutter profile, thread construction and enlarged section views)
- Table 1 (dimension data and thread parameters)
- Notes on sealing surface quality and finish ovality
Key Topics
- Scope and purpose: Establishes dimensional standards for the 100 mm regular vacuum lug finish to ensure interchangeability and reliable sealing in packaging applications.
- Design documentation: The finish design and dimensions are shown graphically in Figures 1 to 3 and numerically in Table 1; unspecified details are left to application requirements.
- Surface and geometry requirements:
- The sealing surface shall be free of checks, dips, crizzles and other defects that may affect functioning.
- Ovality of finish diameters should be minimized; E and T diameters should be concentric where indicated.
- Cross-hatched areas in the enlarged section indicate closure position and cap clearance.
- Production guidance: Cutter profile, lead starts/ends and cutter inclination (α-angle) are defined; where mould opening requires riffles, exceptions are noted.
- Tolerancing: General tolerances for unspecified dimensions are to be applied in accordance with EN 22768-1.
Applications
ISO 9100-13:2005 is used by manufacturers, mould designers, quality engineers and packaging specifiers who require a standardized vacuum lug finish for wide-mouth glass containers. Practical applications include:
- Ensuring cap and closure interchangeability across suppliers
- Specifying finish geometry for mould tooling and cutter profiles
- Verifying sealing surfaces during quality inspections
- Harmonizing packaging interfaces across bottling and food packaging lines
Benefits include improved sealing integrity, predictable closure fit, reduced rejection rates in assembly, and clearer supplier-to-buyer specifications.
Related Standards
- ISO 9100 (series) - other parts covering different nominal sizes and finish types (Parts 1–14)
- EN ISO 9100-13:2005 - European adoption and national implementation details
- EN 22768-1 - general tolerances for linear and angular dimensions (referenced for unspecified tolerances)
For implementation, consult the figures and Table 1 in ISO 9100-13:2005 for the exact cutter profile, thread construction and dimensional values, and apply EN 22768-1 where general tolerances are required.
