ISO 13469:2014

Overview

ISO 13469:2014 - Mechanical joining: form-fit / interference-fit blind rivets and (lock) bolt joints - specifies requirements and qualification of testing procedures for joints made from metallic and non‑metallic materials (including extrusions, cast materials, plastics and fibre‑reinforced plastics such as carbon and glass). The standard defines how to prepare, test and report destructive and non‑destructive examinations of rivet and lock‑bolt joints used in assemblies, excluding civil engineering applications (metal building and steel construction).

Key topics and requirements

• Scope & applicability: Applies to interference‑fit/form‑fit blind rivets and lock bolts for metallic and non‑metallic parent materials; civil engineering structures are excluded.
• Joining Procedure Specification (JPS): Tests must be agreed before testing. A JPS must record variables that affect joint performance: hole and fastener diameters, sheet thicknesses, material properties, clearance/interference, assembly methods, machine type and tolerances.
• Sample size & specimens: At least two samples shall be evaluated. Prefer purpose‑made test specimens (dimensions referenced to ISO 12996, ISO/DIS 16237, ISO 14270, ISO 18592 as applicable).
• Examinations & tests:
  • Visual examination for alignment and obvious defects.
  • Macro‑section/macroscopic examination to verify clearance or elimination of radial play; sections normal to fastener axis should be taken 0.5 mm from the faying surface or mid‑thickness, whichever is smaller.
  • Tensile shear tests (single or double shear) with recording of force vs. elongation to detect slippage and maximum load.
  • Cross‑tension, mechanized peel, fatigue/endurance tests as required by performance needs.
• Reporting & evaluation: Test results and a single joint specimen test report (JPQR) must document loads, failure modes, and any slippage or endurance behaviour.

Practical applications & who uses it

• Users: fastener manufacturers, OEM design and assembly engineers, aerospace, automotive, marine and rail engineers, composite fabricators, testing laboratories and quality assurance teams.
• Use cases: qualifying riveting or lock‑bolt joining procedures, validating joint designs for assemblies with mixed materials, establishing inspection/test protocols for production or prototype validation, and creating traceable JPS documentation for procurement and certification.
