Overview

EN ISO 15979:2002 specifies requirements for open end blind rivets with break pull mandrel and protruding head made of steel body / steel mandrel (St/St). The standard covers dimensional limits, mechanical characteristics and application data for nominal diameters from 2.4 mm to 6.4 mm. It is intended for manufacturers, designers and quality personnel working with blind rivet fastening systems.

Key topics and technical requirements

• Scope and materials
  • Applies to open end blind rivets with break pull mandrel and protruding head, steel body (St) and steel mandrel (St), nominal diameters 2.4–6.4 mm.
• Dimensions and tolerances
  • Defines rivet body, head and shank dimensions and recommended grip ranges. Clearance hole diameters for the component(s) are specified (see table values for each nominal d).
  • Design formulae for shank, head diameter and head height are given (Annex A).
• Surface finish
  • Rivet body: zinc plated (minimum 5 µm) with chromate conversion c2C (finish designation Fe/Zn5c2C).
  • Mandrel finish at manufacturer’s discretion (oil, phosphate+oil, or zinc).
• Mechanical properties and testing
  • Minimum shear and tensile loads and maximum mandrel break loads are specified by nominal diameter (see Table 3). Example values: for d = 4 mm, shear ≥ 1 700 N, tensile ≥ 2 200 N; for d = 6.4 mm, shear ≥ 4 900 N, tensile ≥ 5 700 N.
  • Mandrel push‑out resistance: load to push out mandrel must exceed 10 N.
  • Mandrel head retention: specified retention test loads by diameter (e.g., 40 N for 4 mm).
  • Mechanical testing references: ISO 14589 (blind rivet testing).
• Workmanship and acceptance
  • Rivets must be free from burrs and defects; no cracking after setting when viewed at 5× magnification.
  • Acceptance inspection per ISO 3269.

Applications and who uses EN ISO 15979:2002

• Primary users:
  • Fastener manufacturers and suppliers (production, specification, marking)
  • Design and mechanical engineers (joint design, material selection)
  • Quality inspectors and test labs (acceptance testing, compliance)
  • Procurement and standards teams specifying fasteners for assemblies
• Typical industries:
  • General metal fabrication, construction, HVAC, electronics enclosures, automotive aftermarket and light engineering where blind rivets are used to join sheets or assemblies that are accessible from one side.
• Practical value:
  • Ensures interchangeability, predictable mechanical performance (shear/tensile), correct hole sizing and reliable corrosion protection for open end blind rivets used in single‑side access applications.

Related standards

• ISO 14588 - Terminology and definitions for blind rivets
• ISO 14589 - Blind rivet mechanical testing
• ISO 3269 - Fasteners acceptance inspection
• ISO 4042, ISO 4520 - Coating and conversion finish requirements

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
