ANMERKUNG Obwohl in diesem Dokument nicht erwähnt, stehen Geräte für die automatische Messung der Schicht¬dicke zur Verfügung, die sofort Ergebnisse mit hoher Genauigkeit (< 1 µm) liefern.
Emballage - Tubes souples en aluminium - Méthode de détermination de l'épaisseur de vernis intérieur
Le présent document spécifie des méthodes de détermination de l’épaisseur du film de vernis appliqué à l’intérieur des tubes en aluminium cylindriques ou coniques. Ces méthodes sont des méthodes de référence, qui peuvent également servir de référence lors de l’étalonnage d’autres appareils électroniques appropriés pour la détermination de l’épaisseur d’un revêtement. Il s’applique aux tubes en aluminium utilisés pour le conditionnement de produits pharmaceutiques, cosmétiques, d’hygiène, alimentaires et d’autres produits domestiques et industriels.
NOTE Même s’ils ne sont pas spécifiés dans le présent document, il existe d’autres appareils de mesure automatique de l’épaisseur du film appropriés qui fournissent des résultats instantanés avec une bonne précision (< 1 µm).
Embalaža - Prožne aluminijaste tube - Metoda za merjenje debeline notranje plasti laka
Ta dokument določa metodo za ugotavljanje debeline plasti laka, nanesenega v valjaste in stožčaste aluminijaste tube. Metoda je referenca. Uporablja se lahko tudi kot referenca pri umerjanju drugih elektronskih instrumentov, primernih za določanje debeline teže prevleke, npr. z merjenjem kapacitivnosti z vrtinčnim tokom. Uporablja se za prožne aluminijaste tube, namenjene pakiranju farmacevtskih, kozmetičnih, higienskih, prehrambenih ter drugih gospodinjskih izdelkov.
OPOMBA: Čeprav to ni navedeno v tem standardu, so na voljo ustrezni avtomatski merilniki debeline plasti, ki zagotavljajo takojšnje rezultate z dobro natančnostjo (< 1 µm).

Overview
EN 13048:2022 - Packaging - Flexible aluminium tubes - Internal lacquer film thickness measurement method - defines reference methods for measuring the thickness of the internal lacquer (inner coating) applied to cylindrical and conical aluminium tubes. It applies to tubes used for pharmaceutical, cosmetic, hygiene, food and other domestic products and can serve as a reference for calibrating electronic coating-thickness instruments.
Key topics and technical requirements
- Two permitted measurement approaches
- Eddy-current test: referenced to EN ISO 2360:2017 (amplitude-sensitive eddy-current method) for non-destructive electronic measurement.
- Chemical test: a destructive reference method that separates the internal lacquer by dissolving the aluminium substrate chemically and measuring the free film.
- Chemical test essentials
- Apparatus: micrometer or dial indicator with 0.001 mm (1 µm) precision; oven; extractor fan; glass container; cutting tools; tweezers; filter paper; personal protective equipment.
- Chemicals: solvent to remove external enamel; sodium hydroxide (NaOH) 20 g/100 ml (or hydrochloric acid 10 g/100 ml as an alternative).
- Procedure highlights: cut sample, remove external enamel, immerse in NaOH (under extraction), recover and rinse film, dry between filter paper, oven-dry 1 hour at 80 °C, cool and measure at 10–25 °C.
- Measurement locations: thickness readings are taken at predefined points along the tube (including near the head and at positions 5–10 mm and 10–20 mm from the head as illustrated in the standard).
- Reporting requirements (minimum): reference to EN 13048, batch identification, sample description and dimensions, instrument ID, lacquer type, measured film thickness at specified points, number of samples, number of defects (out-of-spec tubes), acceptance decision, influencing factors, date/place/tester.
- Safety note: handling of hazardous chemicals and ventilation (extractor fan) are required; users must follow applicable safety regulations.
Applications and users
- Who uses it: packaging manufacturers, tube converters, quality control and testing laboratories, brand owners in pharma/cosmetics/food, regulatory bodies, and instrument manufacturers.
- Practical uses
- Acceptance testing of aluminium tubes and internal coatings.
- Calibration and validation of electronic and automatic film-thickness instruments (including systems that give instantaneous results with accuracy <1 µm).
- Quality assurance to ensure compatibility of internal lacquer with product safety and shelf-life requirements.
