Overview
ISO 12290:2000 - "Aerospace - Rivets, solid, in titanium or titanium alloy - Procurement specification" is an ISO procurement standard that defines the characteristics, quality assurance and acceptance requirements for solid titanium or titanium-alloy rivets used in aerospace construction. It is intended to be referenced by contract or definition documents and establishes inspection, testing and documentation practices for manufacturers and procurers.
Key topics and requirements
- Scope and definitions - Precise terminology (batch, rivet sample, rivet wire sample, critical/major/minor defects) to ensure consistent procurement and inspection.
- Manufacturer approval and quality system - Manufacturers are to conform to ISO 9002 model for quality assurance; approval is granted by certification authorities or their representative.
- Acceptance inspection and testing - Acceptance inspections are performed by the manufacturer on each batch with simple random sampling; both non‑destructive and destructive tests are covered and destructive samples may be taken from items that had prior NDT.
- Mechanical and metallurgical tests:
- Double shear strength testing per ISO 17057 (sampling plan specified).
- Drivability (upsetting) test with visual inspection for cracks.
- Hydrogen content limits are specified (measured with high accuracy instruments).
- Dimensional and visual checks - Head and shank dimensions, head angle/protrusion, and surface defects (seams, laps, cold shuts, pits) inspected visually (magnification limits noted) and measured where required.
- Surface treatment and identification - Surface finish/anodizing per definition document; product identification and marking required.
- Sampling and AQL - Sampling plans reference ISO 2859-1 (AQL-based sampling, single/double sampling plans) and include tables for different batch sizes and inspection types.
- Statistical process control (SPC) - ISO/TR 13425 and control-chart standards (ISO 7870, ISO 7966, ISO 8258) may be used to replace final lot sampling if SPC is justified, validated and audited.
- Packaging & labelling - Packaging must protect against damage/corrosion, contain single-batch rivets (max mass noted), and include durable labels with designation, quantity, manufacturer and batch number.
Applications and users
ISO 12290:2000 is used by:
- Aerospace OEMs and tier suppliers specifying solid titanium/titanium-alloy rivets for airframes and structural assemblies.
- Procurement and quality engineers who create purchase orders, definition documents and acceptance criteria.
- Manufacturing engineers and rivet producers for process control, inspection planning and supplier certification.
- Test laboratories performing mechanical/metallurgical verification on batches.
