SIST EN ISO 9100-5:2005

SIST EN ISO 9100-5:2005 is the Slovenian national standard corresponding to EN ISO 9100-5:2005. It specifies the dimensions of vacuum lug finishes with nominal sizes 43 mm and 48 mm regular for wide-mouth glass containers, so container makers, closure suppliers, and inspectors can work to the same mouth-finish geometry.

What does SIST EN ISO 9100-5:2005 specify?

SIST EN ISO 9100-5:2005 specifies the finish dimensions for two vacuum lug finish sizes used on wide-mouth glass containers. The document focuses on the mouth geometry needed for compatible closure fit and reliable vacuum sealing.

Clause 1 gives the scope, and Clause 3 contains the dimensional rules in Figures 1 to 3 and Table 1. Clause 3.2 also shows how to handle unspecified details by using the intended application and the general tolerance standard named in the document.

What are the key requirements of SIST EN ISO 9100-5:2005?

• Clause 1 - Scope: SIST EN ISO 9100-5:2005 applies to vacuum lug finishes of nominal sizes 43 mm and 48 mm regular for wide-mouth glass containers. In practice, this tells you whether the standard fits the container mouth you are designing or checking.

• Clause 3.1 - Controlled geometry: The finish design and dimensions shall follow Figures 1 to 3 and Table 1. In practice, the drawings and table are the controlling reference for tooling, gauges, and acceptance checks.

• Clause 3.2 - Unspecified details and tolerances: Any details not specified are to be selected according to the application, and general tolerances are given by EN 22768-1. In practice, this means suppliers and buyers must agree the remaining details, but common linear and angular tolerance rules still apply.

• Figure 3 - Surface quality and sealing area: The sealing surface is to be free of checks, dips, crizzles, and other defects that could interfere with function. In practice, this is a visual and quality-control point because surface flaws can affect closure performance.

• Figure 3 - Roundness and concentricity: Ovality in the finish diameters is to be kept to a minimum, and the E and T diameters should be concentric. In practice, this means measuring finish shape and alignment, not only size.

• Figure 3 - Closure position and clearance: The cross-hatched areas for C diameter and H height show the closure position, and the glass shall clear the cap limits shown. In practice, the finish must leave enough room for the closure to seat correctly without interference.

• Table 1 - Dimensional parameters: Table 1 sets the key dimensional parameters for each finish type, including E, T, C, cutter angle, thread parameters, pitch, and T.P.I. In practice, these are the values used to design the finish profile and to inspect manufactured containers.

• Table 1 notes - Cutter and thread formation: The cutter inclination at angle α is to be maintained for all cuts, and the start and end of the leads follow the cut-in profile except where riffles are needed for mould opening. In practice, this matters for tooling setup and for how the thread is formed during manufacture.

What terms does SIST EN ISO 9100-5:2005 define?

• Vacuum lug finish - The container mouth finish designed for a vacuum closure with lug engagement.

• Wide-mouth glass container - A glass container with a broad opening that uses this type of finish.

• Cutter profile - The shape of the cut that forms part of the finish geometry.

• Sealing surface - The surface that must remain free of defects because it supports proper closure function.

• Parting line - The mould split line identified in the figures.

• Ovality - Departure from roundness in the finish diameter.

• T.P.I. (threads per inch) - The thread count used to describe the finish thread form.

Who uses SIST EN ISO 9100-5:2005?

SIST EN ISO 9100-5:2005 is used by glass container manufacturers, closure designers, and bottling and packaging engineers who need a common finish geometry for vacuum lug closures. Quality managers and inspection teams use it to check finish dimensions, surface condition, and roundness. Buyers and specifiers use it when they need to state the required mouth finish in procurement documents or supplier agreements.

Which standards are used with SIST EN ISO 9100-5:2005?

EN 22768-1 is the external standard named in the document body, and it supplies general tolerances for linear and angular dimensions without individual tolerance indications. That is the reference to use when a finish detail is not individually dimensioned in this part.

The document is also presented as the Slovenian adoption of EN ISO 9100-5:2005, so the same technical content is available under the ISO/CEN designation.

What does the SIST EN ISO 9100-5:2005 document contain?

SIST EN ISO 9100-5:2005 contains a scope, a short references section, and a dimensional section supported by Figures 1 to 3 and Table 1. The figures show the cutter profile, thread construction, and an enlarged section of the finish, while Table 1 organizes the dimensional data for the 43 and 48 regular finishes.

The document also includes notes on sealing-surface quality, ovality, concentricity, closure clearance, and cutter lead formation. These details support design, tooling, measurement, and inspection of wide-mouth glass container finishes.
