Self-adhesive tapes - Measurement of the length of a roll of adhesive tape

This standard specifies a method to measure the length of adhesive tape on a roll. For non extensible adhesive tapes the length measured by this method shall be the same as the length after unrolling. For extensible adhesive tapes the length after unrolling shall be greater if the adhesive tape is stretched irreversibly by unrolling. It is also possible for an extensible adhesive tape to measure less after unrolling if stress built in during manufacture recovers after unrolling.

Klebebänder - Messung der Länge einer Klebebandrolle

Diese Norm legt ein Verfahren zum Messen der Länge eines Klebebandes auf einer Rolle fest. Für nicht dehnbare Klebebänder müssen die nach diesem Verfahren gemessene Länge und die Länge nach dem Abrollen übereinstimmen. Dehnbare Klebebänder haben nach dem Abrollen eine größere Länge, wenn das Klebeband beim Abrollen irreversibel gedehnt wurde. Es is auch möglich, daß für ein dehnbares Klebeband nach dem Abrollen eine geringere Länge ermittelt wird, falls sich bei der Herstellung aufgetretene Spannungen nach dem Abrollen abbauen.

Rubans auto-adhésifs - Mesure de la longueur d'un rouleau de ruban adhésif

La présente norme prescrit une méthode pour mesurer la longueur de ruban adhésif sur un rouleau. Pour des rubans non extensibles la longueur mesurée par cette méthode sera la même que la longueur après déroulement. Pour des rubans adhésifs extensibles la longueur après déroulement sera plus grande si le ruban adhésif est étiré de manière irréversible par déroulement. Il est également possible pour un ruban adhésif extensible de mesurer moins après déroulement si la contrainte créée pendant la fabrication disparait après déroulement.

Overview

EN 12034:1996 (CEN) specifies a standardized method to measure the length of a self-adhesive or adhesive tape on a roll. The standard clarifies how measured roll length relates to the length after unrolling for different tape types:

• For non-extensible adhesive tapes, the length measured on the roll using this method is expected to equal the length after unrolling.
• For extensible adhesive tapes, the length after unrolling can differ: it may be greater if irreversible stretching occurs during unrolling, or it may be less if residual stresses from manufacture recover after unrolling.

This standard supports consistent length measurement practices across suppliers, manufacturers, testing laboratories, and quality functions.

Key Topics

• Scope and applicability: Measurement of the length of adhesive tape on a roll for product acceptance, inventory, and conformity assessment.
• Behaviour distinctions: Differentiation between non-extensible and extensible tapes and implications for length comparison before and after unrolling.
• Quality implications: How stretching or stress relief affects reported roll length and downstream uses.
• Terminology and definitions: Common terms related to adhesive tape length measurement and roll characteristics.

These topics emphasize practical considerations for accurate measurement and consistent reporting in manufacturing and testing environments.

Applications

• Quality control and production acceptance: Use the standard method to validate advertised roll lengths and ensure consistency on production lines.
• Inventory and stock management: Accurate roll length measurement supports inventory tracking, material yield calculations, and order fulfillment.
• Supplier and purchaser agreements: Provide objective basis for contractual length verification and dispute resolution.
• Laboratory testing and certification: Standardized measurement enables comparable results across testing bodies and laboratories.

Practical benefits include reduced measurement variability, clearer communication between suppliers and buyers, and better correlation between measured roll length and in-use performance for both non-extensible and extensible tapes.

Related Standards

• CEN documents and national adoptions (EN and SIST listings) that align with adhesive and packaging testing practices.
• Other standards covering adhesive properties, tensile behaviour, and tape dimensional stability may be referenced when evaluating extensible tapes and their performance after unrolling.
