Overview

EN 14294:2010 - "Adhesives for leather and footwear materials - Preparation of bonded test pieces by moulding‑on processes" (CEN) defines standardized laboratory procedures to prepare test specimens in which an adhesive‑coated leather or other upper material has a soling material moulded directly onto it. The methods simulate common footwear manufacturing processes: direct vulcanising (rubber), injection moulding (thermoplastics) and reaction moulding (polyurethane). Prepared specimens are intended for bond strength testing according to EN 1392 and for evaluation against the requirements of EN 15307.

Key topics and requirements

• Scope and intent: Procedures produce flat moulded assemblies (soling bonded to upper material) suitable for subsequent peel and creep tests.
• Procedure steps: Surface preparation of upper materials; cutting and conditioning of strips; adhesive application and curing/drying intervals; placement in mould; moulding and curing of soling material; conditioning and sampling of test pieces.
• Materials and identification: Mandatory reporting of adhesive and material details (designation, manufacturer, batch/lot, polymer type, colour). Special note for two‑part adhesives, crosslinkers and reference test adhesives.
• Moulding processes covered:
  • Direct vulcanising (uncured rubber compounds)
  • Injection moulding (thermoplastic compounds such as PVC or SBSR)
  • Reaction moulding (polyurethane prepolymers/resins)
• Apparatus and preparation: Lists typical laboratory equipment (moulds, presses, injection moulder, ovens, applicators, cutting tools) and handling precautions relevant to each moulding method.
• Test piece requirements: Produced specimens must comply with EN 1392 dimensional and conditioning rules for peel and creep tests; number of specimens and reporting requirements are specified.
• Safety and environmental notes: Users must follow lab safety practices and local waste disposal regulations; some permitted materials may have environmental impacts.

Applications and practical value

• Quality control: Allows footwear manufacturers and adhesive suppliers to simulate factory moulding‑on processes under repeatable laboratory conditions to assess sole‑upper bond performance.
• R&D and product development: Useful for developing adhesives and soling compounds tailored to vulcanising, injection or reaction moulding.
• Compliance and certification: Produces specimens usable with EN 1392 testing and EN 15307 evaluation for regulatory or procurement specifications.
• Supplier verification: Standardized method for incoming material checks and batch comparisons.

Who should use this standard

• Adhesive manufacturers and formulators for leather and footwear
• Footwear laboratories and test houses
• R&D teams in shoe and components manufacturing
• Quality assurance and compliance professionals

Introduction EN 15307 and EN 1392 specify methods of testing and evaluation of adhesives for leather and footwear materials in "stuck-on" assemblies. Most footwear produced in Europe is manufactured using stuck-on processes, but a significant proportion is produced by "moulding-on" processes such as vulcanising, injection moulding and reaction moulding. This document specifies the preparation of bonded test pieces by moulding-on processes. The form and dimensions of the test pieces produced allows testing according to the test methods specified in EN 1392, and evaluation of the bond strength obtained according to EN 15307. This document therefore complements the above mentioned series of documents, and together they allow the simulation, testing and evaluation of almost all bonds occurring in common footwear constructions.
