Overview
EN ISO 15982:2002 (adopted by CEN) specifies dimensional, mechanical and application data for open end blind rivets with break pull mandrel and countersunk head made of aluminium alloy (AlA/AlA). The standard covers rivets with nominal diameters from 2.4 mm up to and including 6.4 mm, and defines material, finish, acceptance and testing requirements for reliable blind-side fastening.
Key topics and technical requirements
- Rivet types and materials
- Open end blind rivets with a break pull mandrel and countersunk head.
- Rivet body and mandrel both made of aluminium alloy (AlA/AlA); plain (natural) finish.
- Dimensions and grip ranges
- Nominal diameters: 2.4, 3.2, 4.0, 4.8, 6.4 mm.
- Detailed dimensional tables (head diameter, head height, shank limits, recommended grip ranges) are specified; design formulae for head and shank dimensions are given in Annex A.
- Clearance holes
- Specified clearance hole diameters (dh1) for each nominal rivet size; non‑conformance can impair assembly and reduce mechanical performance.
- Option to enlarge the access-side hole for alignment is noted, with potential strength implications.
- Mechanical properties and testing
- Minimum shear and tensile loads and maximum mandrel break loads are tabulated per nominal size (e.g., 4.0 mm: shear min 850 N, tensile min 1 020 N, mandrel break max 2 700 N).
- Mandrel push-out resistance must exceed 10 N.
- Mandrel head retention test loads are specified by rivet size.
- Mechanical testing and acceptance inspection are to be performed in accordance with ISO 14589 and ISO 3269.
- Workmanship and acceptance
- Rivets must be free from burrs/defects; after setting no cracking visible at 5× magnification.
- Acceptance inspection follows ISO 3269 if not otherwise agreed.
Applications
- Designed for blind-side fastening where only one side of the assembly is accessible.
- Typical use cases include fastening thin sheet materials, enclosure assembly, panels and other applications requiring a flush/countersunk head finish.
- Useful wherever lightweight aluminium fasteners are required and controlled mechanical performance and dimensional interchangeability are important.
Who uses this standard
- Fastener manufacturers and quality control laboratories
- Design and mechanical engineers specifying blind fasteners
- Procurement and compliance teams ensuring parts meet EN ISO 15982:2002
- Assemblers and maintenance teams needing correct hole sizes and installation data
