Overview
EN ISO 15980:2002 specifies requirements for open end blind rivets with a break‑pull mandrel and countersunk (protruding) head, with both rivet body and mandrel made of steel (St/St). The standard covers dimensional, mechanical and application data for nominal diameters from 2.4 mm up to and including 6.4 mm, and defines surface finish, testing and acceptance criteria for these blind rivets.
Key topics and technical requirements
- Scope and sizes: Nominal diameters d = 2.4 mm to 6.4 mm; recommended grip ranges and nominal lengths are specified.
- Dimensions: Detailed rivet geometry (head diameter, head height, shank diameter, blind length) and clearance hole guidance; clearance hole diameter h1 = nominal + 0.1 mm (min) to + 0.2 mm (max).
- Materials and finish: Rivet body and mandrel made of steel (St/St). Rivet body must be zinc plated ≥ 5 µm with chromate conversion coating c2C (designated Fe/Zn5c2C); mandrel finish at manufacturer’s discretion.
- Mechanical properties: Minimum shear and tensile loads and maximum mandrel break loads are specified per nominal diameter. For the range covered, shear spans about 650 N to 4 900 N, tensile 700 N to 5 700 N, and mandrel break load 2 000 N to 13 000 N (values given per size in the standard).
- Performance tests: Mechanical testing, mandrel push‑out resistance (>10 N), and mandrel head retention test loads are required (tests referenced to ISO 14589).
- Workmanship and acceptance: Rivets must be free of burrs and cracking (inspection at 5× magnification); acceptance inspection follows ISO 3269.
Applications
EN ISO 15980:2002 applies to design, manufacture, procurement and quality assurance of steel open‑end blind rivets used where a countersunk head is required on the accessible side. Typical uses include:
- Structural and sheet‑metal assembly in construction, transport, HVAC and metal fabrication
- Equipment and appliance assembly where blind fastening from one side is needed
- Retrofitting and field repairs where access to only one side of the joint is available
Who uses this standard
- Fastener manufacturers and tooling suppliers
- Design and mechanical engineers specifying fasteners
- Procurement and quality inspectors verifying conformity
- Test laboratories performing mechanical tests and acceptance inspections
