Overview
SIST EN ISO 15974:2002 specifies the requirements for closed end blind rivets with break pull mandrel and countersunk head (AIA/St). Developed by CEN and aligned with ISO 15974:2000, this standard ensures consistency and reliability in the design and application of these specific types of blind rivets. These fasteners are extensively used where high strength and flush surface finishes are required, making them crucial for modern manufacturing, construction, and industrial assembly processes.
Key Topics
- Design and Dimensions: The standard covers the structural design of closed end blind rivets, including precise measurements for the countersunk head and break pull mandrel features.
- Material Specifications: SIST EN ISO 15974:2002 applies to rivets made from aluminum alloys and steel, ensuring durability and compatibility with diverse applications.
- Mechanical Properties: Requirements include minimum tensile and shear strength, providing assurances of performance under operational stresses.
- Performance Criteria: Defines the acceptable levels for break load, mandrel retention, and resistance to environmental factors.
- Identification and Marking: Specifies guideline for rivet identification, including head marking for traceability and quality control.
Applications
Closed end blind rivets with break pull mandrel and countersunk head offer widespread industrial advantages due to their strength, ease of installation, and clean finish. Practical applications include:
- Aerospace and Automotive: Securing metal panels or structural parts where a flush finish is critical and access to only one side is possible.
- Construction: Joining metal frameworks, beams, or facades requiring high load-bearing capacity and visual appeal.
- Electronics Enclosures: Assembly of housings and casings, where watertightness or vibration resistance is necessary.
- General Manufacturing: Used in furniture, appliances, and equipment where reliable fastening and aesthetic appearance are both priorities.
These rivets are valued for their secure locking mechanism and sealed end, which prevents ingress of liquids, dust, or gases - vital in harsh environments.
