WG 39 - Flexible tubes

This document specifies a test method for airtightness of the closures for flexible tubes.
It is applicable to flexible tubes used for packing pharmaceutical, cosmetic, hygiene, food and other domestic and industrial products
It is not applicable to flexible tubes with external applicators added on to the tube by the consumer and pumps.

This document specifies methods for the determination of the thickness of the lacquer film applied inside cylindrical and conical aluminium tubes. The methods are a reference. They can also be used as a reference when calibrating other electronic instruments suitable for determining coating weight thickness. It is applicable to aluminium tubes used for packing pharmaceutical, cosmetic, hygiene, food and other domestic products.
NOTE   Although not specified in this document there are available suitable automatic film thickness measurement instruments that provide instantaneous results with good accuracy (<1μm).

This document defines the technical vocabulary in German, French and English, widely in use for flexible tubes.
It is applicable to metal, plastic, multilayer or laminated tubes that are used for packing pharmaceutical, cosmetic, hygiene, food and other domestic or industrial products.

This document specifies a method to test the orientation of the flip-top cap on flexible cylindrical tubes [1].
It is applicable to aluminium, plastic and laminated tubes used for packing pharmaceutical, cosmetic, hygiene, food and other domestic and industrial products.

This document specifies the diameter, length, wall thickness and shoulder geometry of flexible cylindrical plastic tubes.
It is applicable to tubes used for packing pharmaceutical, cosmetic, hygiene, food and other domestic and industrial products.

This document specifies a method to measure the deformation of the aluminium tube body.
It is applicable to cylindrical aluminium tubes used for packing pharmaceutical, cosmetic, hygiene, food and other domestic and industrial products.

This document specifies a method for the determination of the adhesion of the internal and external protective lacquer of aluminium tubes.
It is applicable to aluminium tubes that are coated with an internal or external protective lacquer and which are used for packing, e.g. pharmaceutical, cosmetic, hygiene, food and other household products.

This document is applicable to flexible aluminum tubes.
This document defines the dimensions of the tube nozzle including orifice and thread.

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.

This European Standard is applicable for internally coated cylindrical 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 copper sulphate method to detect the electrolyte conductivity as one criterion for the quality of the internal coating.

This standard specifies a method for the determination of the polymerization of the internal coating of aluminium tubes with acetone.

This standard specifies a method of determination of the thickness of the tube body material of aluminium tubes. It is applicable to tubes used for packing pharmaceutical, cosmetic, hygiene, food and other domestic and industrial products.

This document specifies sizes and geometric characteristics for cylindrical laminated flexible tubes which are produced by directly welding laminate materials. It applies to tubes used for packaging pharmaceutical, cosmetic and hygiene products, as well as for packaging food, industrial and domestic products.

The ammonia test is a quick test to check the chemical resistance of the internal protective coating of aluminium tubes. The test is used for flexible aluminium tubes for ammonia containing fillings and as an introductory test for newly developed internal protective coatings.

This standard specifies a method for the determination of the print adhesion on flexible laminate and plastic tubes.
It is applicable to flexible laminate and plastic tubes used for packing pharmaceutical, cosmetic, hygiene, food and other household products.
