Overview
EN ISO 15977:2002 specifies the requirements for open end blind rivets with break pull mandrel and protruding head, made with an aluminium alloy body and a steel mandrel. These fasteners are designed for secure assembly of components where access is limited to one side only. The standard covers rivets with nominal diameters from 2.4 mm up to and including 6.4 mm, detailing dimensional properties, mechanical performance, application data, and acceptance testing procedures.
By standardizing the characteristics of aluminium-steel blind rivets, EN ISO 15977:2002 supports quality assurance, interchangeability, and reliability in manufacturing and assembly processes across a range of industries.
Key Topics
-
Rivet Design and Construction
- Open end blind rivet structure with a break pull mandrel
- Protruding (domed) head form for effective load distribution
- Aluminium alloy body combined with steel mandrel for strength and corrosion resistance
-
Dimensional Specifications
- Nominal diameters specified: 2.4 mm - 6.4 mm
- Defined length and grip range options for various assembly requirements
- Toleranced shank and head diameters for precise fit
-
Mechanical Characteristics
- Minimum shear and tensile load requirements for two strength grades (Low and High)
- Mandrel break and push-out resistance
- Mandrel head retention under specified test loads
- Surface finish and material combination for performance and durability
-
Acceptance and Workmanship
- Inspection procedures aligned with ISO 3269
- Criteria for finished rivet appearance and freedom from defects
- Recommended hole sizes for proper installation and maintenance of performance values
Applications
Open end blind rivets with break pull mandrels and protruding heads, as defined in EN ISO 15977:2002, are widely used in various applications, including:
These blind rivets are preferred for their ease of installation, reliable load performance, and consistent retention in demanding environments.
