Overview

EN ISO 15236-1:2016 (adopted by CEN) specifies performance, constructional and mechanical requirements for steel cord conveyor belts used for general-purpose material handling. It covers belts reinforced with longitudinal steel cords and defines requirements applicable to individual belts and complete belt type series (see ISO 15236‑2 for preferred types). The document is intended for use in design, testing, procurement and quality control of steel-cord belting across industries that handle bulk materials.

Key Topics

The standard organizes technical requirements into clear design and verification topics, including:

• Belt design and dimensions

  • Standard belt types, belt core design and belt widths
  • Edge width and supporting belt width considerations
  • Cord pitch, number of cords and overall belt thickness

• Mechanical requirements

  • Breaking strength of steel cords and how it applies to belt performance
  • Positioning of steel cords (horizontal and vertical placement) within the belt construction
  • Cord joints: number, spacing and allowed joint arrangements
  • Cord pull-out force and tests to ensure cords remain embedded under load
  • Adhesion between covers and core (bond tests and requirements)

• Covers and durability

  • Cover quality classification and abrasion/aging considerations
  • Ageing of covers (thermal and environmental resistance)
  • Troughability (transverse flexibility) and suitability for conveyor profiles
  • Transverse reinforcements such as breakers and weft layers where applicable

• Safety, testing and conformity

  • Tracking and safety requirements, sampling procedures, designation, ordering data and marking conventions
  • Normative test methods referenced (e.g., ISO tests for traction, adhesion, abrasion, electrical conductivity and flammability)

Applications

EN ISO 15236-1 is practical for professionals who specify, design, manufacture, test or maintain conveyor systems, including:

• Conveyor belt manufacturers and R&D teams
• Mechanical and conveyor system designers/engineers
• Plant and maintenance engineers in mining, bulk material handling, ports, quarrying and recycling
• Procurement/specification writers who need standardized belt performance clauses
• Testing and quality assurance laboratories

Use cases include writing procurement specifications, verifying supplier conformity, designing belt constructions for specific loads and environments, and setting acceptance criteria for delivered belts.

Related Standards

• ISO 15236-2: Preferred belt types (complements Part 1)
• ISO 15236-3: Special safety requirements for underground installations
• ISO 15236-4: Vulcanized belt joints
• Referenced test standards: ISO 7622‑2 (tensile), ISO 7623 (cord-to-coating bond), ISO 8094 (adhesion), ISO 703 (troughability), ISO 10247 (cover classification), plus EN safety and flammability rules

Keywords: steel cord conveyor belts, ISO 15236-1, conveyor belt design, mechanical requirements, belt specifications, cord pull-out, troughability, cover abrasion.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
