Overview - EN ISO 17706:2018 (Footwear uppers tensile test)

EN ISO 17706:2018 (adoption of ISO 17706:2003) is a CEN standard that specifies a laboratory test method for determining the force required to break test specimens taken from footwear uppers, regardless of material. The method measures both breaking strength (N/mm) and tensile elongation (%), providing objective data to assess upper material suitability for end use.

Key topics and technical requirements

• Scope: Uppers including complete upper assemblies (visible outer materials); excludes toe puffs and stiffeners.
• Specimen geometry:
  • Length: 160 mm ± 10 mm.
  • Width: materials that can fray - cut to 35 mm ± 2 mm, then remove threads to reduce to 25.0 mm ± 0.5 mm; non-fraying materials - 25 mm ± 0.5 mm.
  • Six specimens: three along (longitudinal) and three across (transverse) the material.
• Conditioning and sampling:
  • Avoid seams/perforations when cutting specimens.
  • Condition specimens in a standard atmosphere per EN 12222 for at least 48 hours before testing.
  • For leather sampling, refer to prEN 12987 for butt/side selection and backbone direction.
• Apparatus:
  • Tensile testing machine with jaw separation rate 100 mm/min ± 5 mm/min and initial jaw gap 100 mm ± 1 mm.
  • Force-measuring accuracy better than 2% (machine class 2 per EN ISO 7500‑1). Typical force ranges: <1 kN for textiles/coated textiles; up to ~5 kN for thick leather (>2 mm).
  • Cutting tool (press knife), and distance measuring device (accuracy 0.5 mm).
• Test procedure & acceptance:
  • Clamp specimen with 100 mm gauge length; pull until failure.
  • Reject results if specimen slips >2 mm in jaws or fails within 5 mm of a jaw (with exceptions noted).
  • Record breaking force (F) and elongation at break (E).
• Calculations:
  • Breaking strength = F (N) / specimen width (mm) → N/mm.
  • Tensile elongation (%) = (E / GL) × 100, where GL is initial jaw separation (mm).
• Reporting: Include mean breaking strength and mean tensile elongation for each test direction plus test conditions and specimen details.

Applications - who uses this standard

• Footwear manufacturers and component suppliers for material selection and quality control.
• Independent testing laboratories for compliance and comparative performance testing.
• Product development and R&D teams evaluating new upper materials or constructions.
• Procurement and specification writers who require objective tensile strength/elongation data.

Related standards

• EN 12222 - standard atmospheres for conditioning/testing footwear.
• EN ISO 7500‑1 - verification/calibration of tensile testing machines.
• EN 13400 - sampling location and conditioning of samples.
• prEN 12987 - leather sampling guidance.
• ISO 17706:2003 - original international text adopted as EN ISO 17706:2018.

Keywords: EN ISO 17706:2018, footwear, uppers, tensile strength, elongation, test method, breaking strength, tensile testing machine, conditioning, sampling.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 17706 was prepared by CEN (as EN 13522:2001) and was adopted, under a special “fast-track
procedure”, by Technical Committee ISO/TC 216, Footwear, in parallel with its approval by the ISO member
bodies.
For the purposes of international standardization, a list of corresponding International and European
Standards for which equivalents are not given in EN 13522 has been added as Annex ZZ.
