EN 28510-1:2014

• Abstract:

  This part of EN 28510 specifies a 90° peel test for the determination, under specified conditions, of the peel resistance of a bonded assembly of two adherends where at least one adherend is flexible. If a normal tensile testing machine is used for the test, the peel angle will not be constant at exactly 90º. If a constant angle of exactly 90° is required, a roller peeling device is used (see 4.1).; The 90º peel test is particularly suitable for use with less flexible adherends for which a 180° peel test is not suitable because the adherends crack, break or delaminate.; A 180º peel test is described in EN ISO 8510 2.

Overview - EN 28510-1:2014 (90° peel test for adhesives)

EN 28510-1:2014 is a CEN standard that specifies a 90° peel test method to determine the peel resistance of a bonded assembly where at least one adherend is flexible. The method covers apparatus, specimen preparation, conditioning, test procedure and reporting so that peel forces for flexible‑to‑rigid adhesive joints are measured reproducibly under specified conditions. If a constant 90° angle is required a roller peeling device is used; a conventional tensile testing machine may produce a peel angle that is not exactly 90°.

Key topics and technical requirements

• Scope and purpose: Measures peel resistance for assemblies with one flexible adherend; suitable when 180° tests (EN ISO 8510‑2) cause cracking, breakage or delamination of less flexible materials.
• Apparatus:
  • Tensile testing machine with constant grip separation and force measurement (indicated force within ±2% of true force).
  • Optionally a roller peeling device for exact 90° angle.
  • Self‑aligning grip for the flexible adherend; wire connection minimum 600 mm.
• Specimen dimensions & materials:
  • Rigid adherend bonded surface width: (25.0 ± 0.5) mm, minimum length 150 mm (T‑piece recommended).
  • Flexible adherend: (250.0 ± 0.5) mm × (25.0 ± 0.5) mm; must bend >90° without permanent change.
  • Recommended thicknesses (typical): metals 1.5 mm, plastics 1.5 mm, wood 3 mm, compounded rubbers 2 mm.
• Preparation:
  • Surface treatment per EN 13887 or manufacturer instructions.
  • Use a press (hydraulic/pneumatic or mechanical) to apply even pressure (up to 1 MPa recommended).
  • Include an anti‑adhesive strip to create a defined peel start.
• Test procedure:
  • Conditioning per EN ISO 291.
  • Recommended grip separation rate: (50 ± 5) mm/min.
  • Test at least 5 specimens.
• Results & reporting:
  • Determine average peel force over a 50 mm peel length each side of the T‑piece centre; report max/min/average, failure mode (adhesive/cohesive/adherend), specimen details and any deviations.
  • Precision across labs is not established (no inter‑laboratory data).

Applications and users

• Who uses it: adhesive manufacturers, materials/test laboratories, R&D and QA engineers in automotive, aerospace, electronics, packaging and general bonding industries.
• Practical uses: compare adhesive formulations, validate bond performance on flexible films or tapes bonded to rigid substrates, quality control of production adhesives, and material selection where 180° testing is unsuitable.
