EN 13046:2000

Overview

EN 13046:2000 - Packaging - Flexible Cylindrical Metallic Tubes - Dimensions and Tolerances is a European standard developed by the European Committee for Standardization (CEN). This standard defines the essential dimensional requirements and tolerances for flexible, collapsible, cylindrical metallic tubes. These tubes are widely used for packaging applications across a range of industries, including pharmaceuticals, cosmetics, hygiene, food, as well as other domestic and industrial products. The aim of this standard is to ensure product compatibility, safety, efficiency in production, and reliable performance through harmonized tube dimensions and tolerances.

Key Topics

EN 13046:2000 addresses the following key aspects of flexible cylindrical metallic tubes:

• Diameter: Specifies nominal and acceptable range of tube diameters to promote interchangeability and consistency.
• Length: Defines minimum and maximum tube lengths for various applications, supporting efficient packaging and handling.
• Wall Thickness: Outlines required wall thickness and tolerances to guarantee sufficient strength and flexibility.
• Shoulder Thickness: Establishes shoulder dimensions, which are critical for ensuring proper sealing and closure system compatibility.
• Tube Geometry: Sets forth the overall geometrical shape and design parameters to standardize tube structure for industrial use.
• Tolerance Specifications: Details the permissible variations for all defined dimensions, enabling quality control and streamlined manufacturing processes.

Applications

The dimensional and tolerance criteria defined in EN 13046:2000 have broad practical applications, including but not limited to:

• Pharmaceutical Packaging: Ensures metallic tubes are appropriately sized and shaped for medical creams, ointments, and gels, complying with stringent safety and hygiene requirements.
• Cosmetic and Hygiene Products: Standardization enables uniform tube shapes and compatibility with applicators and dispensers.
• Food Packaging: Supports safe and reliable storage of food-grade products such as pastes and sauces, meeting hygiene and contamination resistance needs.
• Industrial and Domestic Products: Suitable for packaging adhesives, lubricants, and household chemicals, optimizing usability and storage.
• Producers and Supply Chain: Facilitates compatibility between tube manufacturers, fillers, and end-users, allowing for efficient mass production and reduced tooling changes.

Meeting the standard ensures ease of product filling, capping, transportation, and end-user dispensing, reducing costs and risk of leakage or failure.
