Overview
ISO 15980:2002 is an international standard specifying the dimensional, mechanical, and application requirements for open end blind rivets with break pull mandrels and countersunk heads, composed entirely of steel. These rivets feature a steel body and a steel mandrel, with nominal diameters ranging from 2.4 mm up to and including 6.4 mm. The standard ensures consistency in manufacturing and performance for these fasteners, which are critical components in mechanical assembly industries.
The standard covers all essential aspects such as dimensions, mechanical properties, surface finish, testing, and quality control to guarantee reliable performance and interoperability of steel open end blind rivets in various applications.
Key Topics
-
Dimensional Specifications:
Defines the exact sizes for rivet diameters (2.4 mm to 6.4 mm), lengths, head dimensions, and hole diameters needed for proper assembly, following formulas and tolerances to guarantee fit and function.
-
Material and Surface Finish:
Mandates the rivet body and mandrel be made of steel (St/St) with corrosion-resistant zinc coatings (minimum 5 μm zinc thickness) and chromate conversion layers (designation c2C) in compliance with ISO 4042 and ISO 4520.
-
Mechanical Characteristics:
Specifies minimum shear loads, tensile strength, and mandrel break forces for each nominal diameter, ensuring rivets can withstand designated mechanical stresses during use.
-
Testing and Quality Assurance:
Includes requirements for mechanical testing according to ISO 14589, as well as acceptance inspection procedures based on ISO 3269 for reception control. Rivets must be free of burrs and defects, with properly formed heads and shanks.
-
Installation Parameters:
Provides recommended grip ranges (material thicknesses to be fastened) and allowable hole diameter tolerances to optimize assembly quality and load capacity.
-
Standardized Nomenclature:
Example designation format:
Rivet aveugle [ISO 15980](/search?q=ISO%2015980) - 4×××× 12 - St/St, indicating diameter, length, and materials per the standard.
Applications
ISO 15980 blind rivets are widely used in applications requiring:
- Reliable and Strong Permanent Fastening: Especially where access is restricted to one side of the assembly (blind installation).
- Steel Assemblies: Suitable for fastening steel sheets and components, typically in automotive, aerospace, electronics, construction, and appliance manufacturing.
- Corrosion-Resistant Joints: With zinc plating and chromate treatment, these rivets are ideal for assembly environments exposed to moisture and mild corrosive conditions.
- Precision Engineering: Compliance with tight dimensional tolerances makes these rivets suitable for demand-critical fastening requiring repeatable quality and durability.
