Overview
ISO 15982:2002 defines the dimensional, mechanical and application data for open end blind rivets with a break-pull mandrel and countersunk head, for rivets with an aluminium alloy body (AlA) and an aluminium alloy mandrel (AlA). The standard covers nominal diameters from 2.4 mm to 6.4 mm and includes requirements for dimensions, materials, mechanical performance and acceptance testing.
Key topics and requirements
- Scope & materials
- Rivet body and mandrel: aluminium alloy (AlA).
- Surface finish: plain (natural).
- Dimensions
- Nominal diameters: 2.4, 3.2, 4.0, 4.8, 6.4 mm.
- Detailed limits for shank, head diameter, head height, rivet length and recommended grip ranges are specified (see annex A design formulae).
- Clearance hole diameters for each nominal size are specified to avoid assembly problems and maintain performance.
- Mechanical properties (minimums per ISO 14589 testing):
- Shear load (N): 250 (2.4 mm), 500 (3.2 mm), 850 (4.0 mm), 1 160 (4.8 mm), 2 050 (6.4 mm).
- Tensile load (N): 350, 670, 1 020, 1 420, 2 490 respectively.
- Mandrel break load (N, max): 1 100, 1 800, 2 700, 3 700, 6 300 respectively.
- Mandrel retention & push-out
- Mandrel push-out resistance must exceed 10 N.
- Mandrel head retention test loads: 10 N (2.4 mm) up to 50 N (6.4 mm).
- Workmanship & inspection
- Rivets must be free from burrs and harmful defects; no cracking after setting when viewed at 5× magnification.
- Acceptance inspection: ISO 3269 applies unless otherwise agreed.
- Designation example
- Blind rivet ISO 15982 - 4 ×××× 12 - AlA/AlA (4 mm × 12 mm, AlA body/mandrel).
Applications and who uses this standard
ISO 15982 is used by:
- Fastener manufacturers designing and certifying aluminium open-end blind rivets.
- Product designers and mechanical engineers specifying reliable, flush fastenings in sheet assemblies and lightweight structures.
- Quality and procurement teams ensuring rivet batches meet dimensional and mechanical criteria.
- Maintenance and assembly operations that require consistent blind-fastening performance where access is only from one side.
Common practical uses include panel fastening, sheet metal joins, and applications where a countersunk, flush head is required and aluminium-to-aluminium fasteners are preferred.
