SIST EN 15384-1:2017
(Main)Packaging - Test method to determine the porosity of the internal coating of flexible aluminium tubes - Part 1: Sodium chloride test
General Information
- Abstract
This European Standard is applicable for internally coated cylindrical and conical aluminium tubes, mainly used for the packing of pharmaceutical, cosmetic, hygiene, food or other household products.
The internal coating is used as a barrier and should avoid any contact between aluminium and the product. This European Standard defines the sodium chloride method to detect the electrolyte conductivity as one criterion for the quality of the internal coating.
NOTE The electrolyte conductivity of the internal coating is only one criterion for evaluation of the quality of an internal coating. It does not give any information on the quantity or size of any pores or uncoated areas, nor any hint on possible reactions between the aluminium tube and the product. The electrolyte conductivity is never used as the sole criterion for quality evaluation of the internal coating, but always with other parameters, e.g. film thickness, acetone and/or ammonia resistance and of course results of enhanced stability studies.

Overview
SIST EN 15384-1:2017 specifies a standardized test method for determining the porosity of the internal coating of flexible aluminium tubes, using the sodium chloride test. These aluminium tubes, both cylindrical and conical, are commonly used as packaging for pharmaceutical, cosmetic, hygiene, food, and other household products. The purpose of the internal coating is to create a barrier that prevents direct contact between the aluminium and the product, thus maintaining quality, safety, and product integrity.
The sodium chloride test outlined in this European Standard assesses the electrolyte conductivity of the internal coating as one indicator of coating quality. While electrolyte conductivity provides valuable information, it is only one aspect of evaluating the coating's protective performance and should be used together with other criteria (e.g., coating thickness, chemical resistance) for comprehensive quality assurance.
Key Topics
- Purpose of Internal Coating: To prevent interaction between the packaged product and aluminium tube material by acting as a barrier.
- Test Principle: The sodium chloride test uses an enamel conductometer and a sodium chloride solution to detect the presence of pores or flaws in the internal coating, measured via induced current.
- Applicability: Relevant to aluminium tubes used for sensitive contents requiring high-quality barrier properties, such as pharmaceuticals and food products.
- Complementary Criteria: The test for electrolyte conductivity must be supplemented by checks on film thickness, chemical resistance, and results from stability studies for a thorough evaluation.
- Testing Apparatus: Includes an enamel conductometer, stainless steel electrodes, and a sodium chloride electrolyte solution prepared to specific concentrations.
Applications
The SIST EN 15384-1:2017 standard offers practical value for industries and laboratories dealing with packaging integrity, especially where product safety and regulatory compliance are critical. Applications of this standard include:
- Quality Control: Routine testing in production to ensure the integrity and uniformity of the internal coating of aluminium tubes.
- Supplier Evaluation: Auditing and qualification of tube suppliers by verifying compliance with electrolyte conductivity requirements.
- Regulatory Compliance: Meeting European and global market requirements for packaging materials in the pharmaceutical, food, cosmetics, and household sectors.
- Product Development: Assessing new coating formulations or tube designs to ensure they offer sufficient barrier protection as part of R&D activities.
- Failure Analysis: Identifying the root cause of packaging failures, such as product contamination or corrosion, by testing for coating defects.
Related Standards
To gain a comprehensive approach to flexible aluminium tube quality and packaging compliance, the following related standards are often used in conjunction:
- EN 12374: Packaging - Flexible tubes - Terminology
- Provides essential definitions for terms used in aluminium tube packaging.
- EN 13046: Packaging - Flexible cylindrical metallic tubes - Dimensions and tolerances
- Details dimensional standards for cylindrical tubes.
- EN 13047: Packaging - Flexible conical metallic tubes - Dimensions and tolerances
- Covers dimensional requirements for conical tubes.
- ISO 2859-1: Sampling procedures for inspection by attributes
- Defines sampling schemes used for batch acceptance, ensuring representative quality control.
By applying SIST EN 15384-1:2017, manufacturers and quality assurance professionals can systematically assess the porosity of internal coatings, reducing the risk of contamination and extending product shelf life-a critical component of best practices in aluminium packaging.
