EN ISO 17698:2016 PDF

Overview

EN ISO 17698:2016 - Footwear - Test methods for uppers - Delamination resistance (ISO 17698:2016) is a CEN-adopted ISO standard that specifies a laboratory test method to determine the delamination resistance of coated materials used for footwear uppers. The method assesses the strength of adhesion between a coating and its base material (peel/delamination behaviour) to judge suitability for end use. This second edition (2016) supersedes EN 13514:2001 and is based on the IULTCS/IUF 470 method.

Key topics and technical requirements

• Scope: Test method for delamination resistance of coated uppers, including dry, wet and hydrolysed conditions.
• Principle: Bond the coated surface of the test specimen to resin rubber and measure the force required to peel the coating from the base material using a tensile testing machine.
• Apparatus and materials (examples from the standard):
  • Tensile testing machine with jaw separation rate (100 ± 10) mm/min and force measurement accuracy > 2 % (ISO 7500‑1, class 2).
  • Autographic recorder or equivalent for continuous force recording.
  • Rapid acting platen press (≈ 550 ± 50 kPa on 50 × 70 mm).
  • Resin rubber (3.5 ± 0.2 mm, hardness 95 ± 2 IRHD), rubber pad (≥ 10 mm, hardness 40 ± 10 IRHD).
  • Radiant heater able to heat adhesive film to 80–90 °C within 15 s and means to verify temperature (heat‑sensitive crayons or IR thermometer).
  • Solvent‑borne polyurethane adhesive and optional adhesion primer.
• Specimen preparation and sampling: Defined marking, cutting, orientation (machine/X-axis), paper tab attachment and assembly dimensions (examples: 50 × 70 mm pieces; smaller sizes permitted if necessary).
• Test procedure: Adhesive application and drying, bonding to resin rubber, heating/reactivation, peeling at defined rate, and recording of force/time.
• Reporting: The standard sets out required details for test reports (sampling, conditioning, apparatus, results and any deviations).

Practical applications and users

Who uses EN ISO 17698:2016:

• Footwear manufacturers and component suppliers for quality control and supplier verification.
• Test laboratories and R&D teams evaluating coated fabrics, PU‑coated uppers and adhesive systems.
• Product development and durability assessment to compare materials and construction choices.
• Compliance and procurement teams requiring objective performance data for acceptance criteria.

Benefits:

• Standardized peel/delamination testing for repeatable comparisons.
• Supports decisions on material selection, adhesive systems and manufacturing processes.
• Enables assessment under dry, wet and aged/humid conditions to simulate end‑use environments.
