ISO 17057:1999

Overview

ISO 17057:1999 - Aerospace - Rivets, solid - Test method specifies a standardized test method for solid rivets used in aerospace construction. The International Standard defines the required test device, fixture characteristics, and test procedure for determining rivet shear performance when used in conjunction with the relevant procurement specification that references this standard.

Keywords: ISO 17057, solid rivets, aerospace rivets, test method, rivet shear test, rivet inspection

Key topics and technical requirements

• Scope: Applies to solid rivets intended for aerospace construction where the procurement specification refers to ISO 17057.
• Test type: Double shear inspection and test using a purpose-designed fixture.
• Testing machine: Machine accuracy must be verified to ISO 7500-1:1999 (class of testing machine range 1,0). The machine shall be calibrated as specified in Annex A.
• Test fixture: Made of steel with a minimum hardness of 530 HV30; dimensions conform to the figure provided in the standard. Machined steel bolts and polished interfaces are required to minimize distortion and wear.
• Procedure:
  • Place rivet or riveting wire so full bearing surface contacts the fixture.
  • Record the maximum load F at fracture (or stop once required minimum ultimate test load is reached).
  • Calculate shear strength from the measured peak load and the actual rivet diameter at the shear zone (the standard provides the formula and defines d as the actual diameter).
• Test speed: ≤ 20 mm/min (0.75 in/min).
• Calibration and traceability: Annex A requires periodic calibration of test apparatus at intervals not exceeding 12 months, performed by a national official body, an organization controlled by such a body, or using standards traceable to a national standards body.

Practical applications

• Quality assurance and acceptance testing of solid rivets used in aircraft and spacecraft structures.
• Verifying rivet shear strength for procurement, incoming inspection, and production control.
• Supporting aerospace fastener qualification and compliance with contract or regulatory requirements.

Who should use this standard

• Aerospace manufacturers and structural assembly shops
• Fastener suppliers and inspectors
• Materials and test laboratories performing mechanical testing on rivets
• Procurement and quality assurance engineers specifying rivet acceptance criteria

Related standards

• ISO 7500-1:1999 - Metallic materials: verification of static uniaxial testing machines (tension/compression) - verification and calibration of force-measuring systems
• Procurement specifications for aerospace rivets that reference ISO 17057

Using ISO 17057 ensures consistent, reproducible rivet shear testing and helps organizations demonstrate compliance with aerospace fastener performance requirements.
