Self-adhesive tapes - Measurement of tear resistance by the pendulum

This standard specifies the method to measure the force required to tear certaintypes of adhesive tape under standard test conditions. Details of the test method depend upon the width of the adhesive tape under test. For adhesive tapes less than 63,5 mm width it is necessary to use Annex A (normative).

Klebebänder - Messung der Reißfestigkeit mit dem Pendelverfahren

Diese Norm legt das Verfahren zum Messen der Kraft fest, die zum Zerreißen bestimmter Ausführungen von Klebebändern unter Normprüfbedingungen erforderlich ist. Einzelheiten des Prüfverfahrens hängen von der Breite des zu untersuchenden Klebebandes ab. Bei Breiten unter 63,5 mm muß der (normative) Anhang A angewendet werden.

Rubans auto-adhésifs - Mesure de la résistance au déchirement par la méthode du pendule

La présente norme prescrit une méthode pour mesurer la force nécessaire pour déchirer certains types de ruban adhésif dans des conditions d'essais spécifiées. Les détails de la méthode d'essai dépendent de la largeur du ruban adhésif soumis à l'essai. Pour les rubans adhésifs dont la largeur est inférieure à 63,5 mm, il est nécessaire d'utiliser l'annexe A (normative).

Overview

EN 12025:1996 - "Self-adhesive tapes - Measurement of tear resistance by the pendulum" is a CEN standard that defines a pendulum-based test method for determining the force required to tear specified types of self-adhesive tapes under standard test conditions. The procedure and reporting requirements vary depending on tape width; for tapes narrower than 63.5 mm the standard requires the use of Annex A (normative). EN 12025 is classified under ICS 83.180 (Adhesives) and was adopted nationally as SIST EN 12025:1997.

Key topics and requirements

• Scope and applicability: Specifies which types of self-adhesive tapes are covered and the intended purpose of the pendulum tear test.
• Pendulum test principle: Uses a pendulum impact/tear technique to measure the resistance of tape to tearing; results express the force or energy required to propagate a tear.
• Specimen preparation and conditioning: Requires tapes to be prepared and conditioned under defined test conditions before measurement (standard laboratory conditions).
• Width-dependent procedure: Test setup and details vary with specimen width; tapes < 63.5 mm must follow Annex A (normative).
• Reporting and interpretation: Defines how to record and report tear resistance results and any relevant test parameters or deviations.
• Reference identification: Standard reference number, adoption information (e.g., SIST EN 12025:1997), and ICS classification for traceability.

Applications and users

EN 12025 is intended for practical use by:

• Adhesive tape manufacturers for quality control and product development, ensuring consistent tear performance.
• Independent testing laboratories performing standardized tear-resistance testing and certification.
• Procurement and specification writers who need objective test methods to compare tape performance.
• R&D teams evaluating new adhesive systems, backing materials, or laminate constructions.
• Regulatory and conformity assessment bodies that require standardized measurement methods.

Typical applications include testing packaging tapes, masking tapes, electrical tapes and specialty self-adhesive products where tear resistance affects performance, handling and end-use reliability.

Related standards

• EN 12025 should be considered alongside other adhesive and tape test standards for tensile strength, peel adhesion, and elongation to provide a comprehensive assessment of tape performance.
• National adoptions (e.g., SIST EN 12025:1997) reflect local implementation and may include language-specific front matter.
