SIST EN 13047:2001

Overview

EN 13047:2000 is a European standard published by CEN that defines the dimensions and tolerances for flexible conical (collapsible) metallic tubes. The standard covers the geometric characteristics manufacturers must follow - including diameters, lengths, wall thicknesses and shoulder thicknesses - and sets requirements for how these tubes are stacked for supply. It is intended for tubes used in pharmaceutical, cosmetic, hygiene, food and other domestic and industrial product packaging.

Key topics and requirements

• Dimensional specifications: required diameters and overall lengths for conical metallic tubes to ensure consistent sizing and interchangeability.
• Wall and shoulder thicknesses: minimum/nominal wall thickness and shoulder geometry tolerances to maintain mechanical integrity and sealing performance.
• Geometric characteristics: profile and shape requirements that define conical tube form and fit.
• Tolerance limits: allowable deviations for each geometric parameter to support quality control and production consistency.
• Stacking and packing: specified method(s) for how tubes should be stacked/packed by the manufacturer for transport and storage, reducing damage and deformation during handling.
• Scope of application: explicitly applies to tubes used for packaging pharmaceuticals, cosmetics, hygiene products, foods and other domestic/industrial goods.

(Note: EN 13047:2000 provides dimensional and tolerance requirements; specific performance tests, closure interfaces, or filling-line adaptation may be covered by other standards or contractual specifications.)

Applications

• Ensures interchangeability between tube manufacturers and converters (e.g., filling and capping equipment suppliers).
• Guides product designers and packaging engineers when specifying tube geometry for new formulations (creams, pastes, ointments, food pastes, adhesives).
• Supports quality control and incoming inspection: procurement teams and QA labs use the standard to verify compliance of supplied tubes.
• Helps logistics and storage teams with stacking/packing rules that reduce deformation and shipping damage.
• Useful in regulatory documentation where conformity to recognized standards is required for market access.

Who should use this standard

• Tube manufacturers and converters
• Packaging engineers and product development teams in pharmaceutical, cosmetic, food and hygiene industries
• Procurement, quality assurance and regulatory affairs professionals
• Equipment suppliers (filling and sealing machinery) verifying part compatibility
