IEC 60454-2:2007

Overview

IEC 60454-2:2007 - third edition - is the International Electrotechnical Commission standard that defines methods of test for pressure-sensitive adhesive tapes for electrical purposes. It specifies standardized test methods, specimen preparation and conditioning, and how to record and report results for electrical tapes used as insulation, bundling or protective wrap. This edition includes improved wording for the flame test (Clause 20), revised text on adhesion (Clause 11), and adds new illustrations (Figures 9a and 9b) related to flame-test enclosures.

Key topics and technical requirements

The standard focuses on practical, repeatable test procedures relevant to electrical tape performance. Major test topics include:

• Specimen conditioning and preparation - ensuring consistent pre-test conditions.
• Dimensional measurements - thickness, width and roll length determination.
• Mechanical properties - tensile strength and elongation at break.
• Adhesion - peel/adherence tests including updated Clause 11 procedures and expression of results.
• Low-temperature behavior - flexibility and electrical strength after cold conditioning.
• Thermal endurance - referencing IEC 60216 series for thermal ageing and life assessment.
• Electrical properties - dielectric strength and electrical strength after humid conditioning.
• Corrosion-related properties - pH, conductivity, detection of corrosive sulfur and other effects on metals.
• Flame and fire behavior - Clause 20 flame test and resistance to flame propagation procedures (updated wording and new Figures 9a/9b for draught protection and burner use).
• Other tests - water-vapour permeability, flagging, shear adhesion after liquid immersion, cure behavior for thermosetting adhesives.

The document provides apparatus descriptions, specimen geometries and clear result reporting formats to support reproducible testing.

Applications and who uses this standard

IEC 60454-2:2007 is intended for stakeholders involved in the manufacture, testing and specification of electrical pressure-sensitive adhesive tapes, including:

• Tape manufacturers and R&D teams validating product performance.
• Independent test laboratories and quality assurance groups performing type and batch testing.
• Product compliance and certification bodies assessing safety and electrical performance.
• Specifiers and procurement professionals writing technical requirements for electrical tapes used in wiring harnesses, electrical insulation, repair, and OEM assemblies.

Using this standard helps ensure consistent, internationally recognized test methods for product comparison, regulatory compliance and safety risk mitigation.

Related standards and notes
