Overview

SIST EN ISO 15981:2003 is a comprehensive standard published by CEN that specifies the dimensional and mechanical characteristics of open-end blind rivets with break pull mandrels and protruding heads. These rivets have an aluminium alloy body (AlA) and an aluminium alloy mandrel (AlA), suitable for various fastening applications. The standard covers nominal diameters ranging from 2.4 mm to 6.4 mm, ensuring compatibility and performance across a broad spectrum of fastening needs in industrial and manufacturing settings.

Key Topics

• Rivet Dimensions: The standard defines detailed dimensional specifications including nominal diameters, head diameter, shank diameter, rivet body length, and grip ranges. For instance, nominal diameters span from 2.4 mm to 6.4 mm with corresponding clearances for optimized fit and assembly ease.
• Mechanical Characteristics: EN ISO 15981 specifies minimum shear and tensile loads for each rivet size, ensuring structural integrity under stress. For example, a 4.8 mm rivet must withstand minimum shear loads of 1,160 N and tensile loads of 1,420 N, with maximum mandrel break loads defined to prevent premature failure.
• Material Specifications: The rivet body and mandrel must both be made from aluminium alloys (AlA), delivered in a natural finish to ensure corrosion resistance and mechanical reliability.
• Clearance Hole Dimensions: Recommended diameters for clearance holes are outlined to facilitate proper rivet insertion without compromising strength. The standard advises permissible tolerances and the impact of enlarged holes on shear and tensile strength.
• Testing and Inspection: The standard refers to ISO 14589 for mechanical testing and ISO 3269 for acceptance inspection, ensuring rivets meet quality benchmarks regarding durability, mandrel retention, and absence of defects after installation.
• Workmanship: Rivets must be free from burrs and other harmful defects, with well-formed heads and shanks to ensure safe and consistent performance.

Applications

SIST EN ISO 15981:2003 rivets are widely used in industries where reliable and lightweight fastening is critical, including:

• Automotive manufacturing: Fastening body panels and components where aluminium alloys are preferred for weight reduction.
• Aerospace and aviation: Securing non-structural components requiring high strength-to-weight ratios.
• Electronics and appliances: Assembly of enclosures and internal components needing durable, corrosion-resistant fasteners.
• Construction and metal fabrication: Joining thin sheet metals or securing components where blind access is necessary.
• General manufacturing: Fastening applications in machinery and equipment where standardized rivet dimensions and mechanical characteristics streamline production and maintain safety compliance.

Related Standards

SIST EN ISO 15981:2003 aligns and references multiple related standards to ensure comprehensive quality and compatibility:

• ISO 14588:2000 - Terminology and definitions related to blind rivets, ensuring consistent understanding across documents and industries.
• ISO 14589:2000 - Mechanical testing methods for blind rivets, used to verify conformity with strength and mandrel retention requirements.
• ISO 3269:2000 - Acceptance inspection procedures for fasteners, guiding quality assurance processes.
• ISO 14580 Series - Covers various aspects of rivet fasteners that may complement the application of EN ISO 15981 rivets.
