Overview

EN ISO 15976:2002 is an international standard specifying the dimensional, mechanical, and application characteristics of closed end blind rivets with break pull mandrel and protruding head, constructed with a steel body and steel mandrel. This standard applies to rivets with nominal diameters ranging from 3.2 mm to 6.4 mm. Developed by ISO/TC 2 (Fasteners) in collaboration with CEN/TC 185, EN ISO 15976:2002 ensures uniformity and reliability across European and international fastener applications. The standard supports high-quality fastening solutions in mechanical and construction industries where secure blind riveting is critical.

Key Topics

• Scope and Application
  The standard covers blind rivets with break pull mandrel systems and protruding heads made entirely from steel (steel body and steel mandrel). The nominal diameter range is from 3.2 mm up to 6.4 mm inclusive.

• Dimensions and Tolerances
  Rivet dimensions including body length, head diameter and height, shank diameter, and grip range are precisely defined. Compliance with these ensures proper fit and mechanical performance in assembly.

• Mechanical Properties
  Minimum shear loads, tensile loads, and maximum mandrel break loads are stipulated for each nominal diameter category to guarantee rivet strength and durability when subjected to mechanical forces.

• Material and Finish
  Steel body and mandrel rivets must have a zinc plating of at least 5 µm with a c2C chromate conversion coating according to ISO 4042 and ISO 4520, providing corrosion resistance and surface protection.

• Workmanship and Quality Control
  Rivets must be free from burrs and defects, with well-formed heads and shanks. No cracking is allowed after setting, verified under magnification.

• Testing and Acceptance
  Testing for conformity follows the acceptance inspection procedures per ISO 3269 and mechanical testing per ISO 14589, ensuring consistent quality.

• Designation Format
  Example: Blind rivet ISO 15976 - 4××××12 - St/St indicates a 4 mm nominal diameter, 12 mm length, steel body, and mandrel rivet with closed end and protruding head.

Applications

EN ISO 15976 compliant rivets are widely used in:

• Automotive assembly – joining sheet metal components where access is limited to one side.
• Aircraft and aerospace manufacturing – for lightweight, secure fastening.
• Construction and infrastructure – steel frame assemblies requiring corrosion-resistant fasteners.
• Electrical and mechanical equipment – fastening of panels, enclosures, and structural supports.
• General manufacturing – any industry that demands reliable blind rivet fasteners with strict dimensional and mechanical standards.

The closed end design provides sealed fastening, preventing ingress of moisture or contaminants, enhancing durability in harsh environments.

Related Standards

This standard references and harmonizes with several key ISO norms:

• ISO 14588:2000 – Terminology and definitions for blind rivets, ensuring consistent language and understanding.
• ISO 14589:2000 – Mechanical testing methods for blind rivets, standardizing quality assessment.
• ISO 3269:2000 – Acceptance inspection procedures for fasteners.
• ISO 4042:1999 – Specifications for electroplated fasteners coatings.
• ISO 4520:1981 – Requirements for chromate conversion coatings on electroplated zinc and cadmium.

These complementary standards collectively enhance the consistency, quality, and application reliability of blind rivets specified under EN ISO 15976:2002.
