Overview

ISO 8755:2001 - Commercial road vehicles - 40 mm drawbar eye - Interchangeability defines the dimensional and performance characteristics required for 40 mm drawbar eyes to ensure safe interchangeability of coupling components between towing vehicles and trailers. The standard applies to mechanical connections for commercial vehicles and trailers with a maximum total mass above 3.5 t. It ensures compatibility between drawbar eyes and corresponding C 40 drawbar couplings, preventing axial rotation and standardizing identification.

Key topics and requirements

  • Scope and applicability
    • Covers 40 mm drawbar eyes used on commercial road vehicles and trailers > 3.5 t.
  • Designation and marking
    • Drawbar eyes are identified by reference to the standard and code (e.g., Drawbar eye ISO 8755 D 40, or D 40-C for classified types).
  • Dimensional requirements
    • Characteristic dimensions are given (figures and tables). Example limits include maximum characteristic dimensions for non-classified D 40 (see ISO text for exact values).
    • Drawbar eyes with sleeves must meet specific sleeve dimensions (slotted or non‑slotted).
  • Classes and characteristic values
    • Classified types D 40-A, D 40-B, D 40-C have defined dimensional variants and minimum characteristic performance values (Table 3 in the standard), with D 40‑C having higher vertical load capability.
  • Mechanical performance and testing
    • All 40 mm drawbar eyes must be tested according to ISO 8718 or ISO 12357 (strength tests for hinged and rigid drawbars respectively).
  • Interchangeability requirements
    • Specifies that D 40 eyes must mate with C 40 couplings and restrict axial rotation to ensure safe, interchangeable coupling.

Applications and users

  • Manufacturers of drawbar eyes, drawbar couplings and trailer components use ISO 8755:2001 to design parts that are dimensionally compatible and certifiable for international markets.
  • OEMs and trailer builders adopt the standard to ensure replacement and aftermarket parts fit consistently and safely.
  • Testing laboratories and certification bodies apply the specified strength tests and verification criteria.
  • Fleet operators and maintenance shops rely on the standard for correct part selection, safe replacements and compliance with interoperability requirements.
  • Regulators and homologation authorities reference the standard when setting vehicle coupling safety requirements.

Related standards

  • ISO 8718 - Drawbar couplings and eyes (strength tests, hinged drawbars)
  • ISO 12357 - Drawbar couplings and eyes (strength tests, rigid drawbars)
  • ISO 3584 - Drawbar couplings - Interchangeability
  • ISO 11406 / ISO 11407 - Operating clearance and mechanical coupling interchangeability for specific trailer/towing arrangements

ISO 8755:2001 is essential for ensuring safety, interchangeability and international compatibility of 40 mm drawbar eye couplings used on commercial road vehicles.

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 3.
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 International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 8755 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee
SC 15, Interchangeability of components of commercial vehicles and buses.
This second edition cancels and replaces the first edition (ISO 8755:1986), which has been technically revised.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée aux
comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du comité
technique créé à cet effet. Les organisations internationales, gouvernementales et non gouvernementales, en
liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec la Commission
électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI, Partie 3.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur publication
comme Normes internationales requiert l'approbation de 75 % au moins des comités membres votants.
L’attention est appelée sur le fait que certains des éléments de la présente Norme internationale peuvent faire
l’objet de droits de propriété intellectuelle ou de droits analogues. L’ISO ne saurait être tenue pour responsable de
ne pas avoir identifié de tels droits de propriété et averti de leur existence.
La Norme internationale ISO 8755 a été élaborée par le comité technique ISO/TC 22, Véhicules routiers,
sous-comité SC 15, Interchangeabilité des composants des véhicules utilitaires et autobus.
Cette deuxième édition annule et remplace la première édition (ISO 8755:1986), qui a fait l'objet d'une révision
