Overview
EN ISO 15984:2002 (ISO 15984:2002) specifies dimensional, mechanical and application data for open end blind rivets with break pull mandrel and countersunk head, manufactured from austenitic stainless steel A2/A2. The standard covers nominal diameters from 3 mm to 5 mm and defines geometry, material, mechanical properties and acceptance/testing references for these blind fasteners.
Key topics and requirements
- Scope and materials
- Rivet body and mandrel both A2 (austenitic stainless steel) in accordance with ISO 3506‑1.
- Plain (natural) finish required.
- Dimensions and tolerances
- Nominal diameters: 3; 3.2; 4; 4.8; 5 mm.
- Detailed head, shank and length dimensions plus recommended grip ranges are provided (see Table 1 and Figure 1 in the standard).
- Clearance hole diameters (h1) are specified to avoid assembly problems and strength reductions.
- Mechanical performance
- Minimum shear and tensile loads and maximum mandrel break loads are specified and tested per ISO 14589. Examples:
- 3 mm: shear ≥ 1 800 N, tensile ≥ 2 200 N, mandrel break ≤ 4 100 N
- 4 mm: shear ≥ 2 700 N, tensile ≥ 3 500 N, mandrel break ≤ 6 500 N
- 5 mm: shear ≥ 4 700 N, tensile ≥ 5 800 N, mandrel break ≤ 9 000 N
- Mandrel push‑out resistance must exceed 10 N.
- Mandrel head retention test loads are specified (e.g., 35 N for 3/3.2 mm, 40 N for 4 mm, 45 N for 4.8/5 mm).
- Quality and acceptance
- Workmanship rules: burr‑free, well‑formed heads/shanks, no cracking after setting (5× magnification).
- Acceptance inspection defaults to ISO 3269 unless otherwise agreed.
- Designation
- Example: Blind rivet ISO 15984 - 4 ×××× 12 - A2/A2
Applications and who uses it
- Typical use: blind fastening where only one side of an assembly is accessible (sheet metal assemblies, enclosures, HVAC, building façade panels, general manufacturing).
- Benefits of the A2/A2 combination: corrosion resistance and compatibility where stainless fasteners are needed and a countersunk head for flush finish is required.
- Primary users:
- Fastener manufacturers and product designers specifying rivet geometry and performance
- Mechanical and structural engineers specifying blind fasteners for assemblies
- Quality inspectors and test laboratories performing acceptance testing
- Procurement teams ensuring conformity to EN ISO 15984 for stainless steel countersunk blind rivets
