Overview
ISO 12288:2000 is an International Standard from ISO that defines procurement, quality and inspection requirements for solid rivets made from nickel alloy used in aerospace construction. It specifies the characteristics, acceptance inspection methods, sampling plans and quality assurance obligations that apply whenever a definition document (drawing, product standard or in‑house spec) references this procurement specification.
Key topics and requirements
- Material and dimensions
Material must comply with the referenced product or material standard; dimensions are checked per the product standard with projection measurement as reference in case of dispute.
- Quality assurance and manufacturer approval
Manufacturers are required to have a quality system (reference to ISO 9002 in the standard) and must be approved by the certification authority or prime contractor.
- Acceptance inspection and sampling
Acceptance tests are carried out per batch with simple random sampling. Sampling plans reference ISO 2859-1 (AQL sampling) and specific tables in ISO 12288 for visual, dimensional and mechanical tests.
- Mechanical and metallurgical tests
Double shear strength is verified (test method ISO 17057). Grain size must be finer than size 5 per ASTM E112. Drivability (upsetting) tests are defined and must show no cracking.
- Surface treatment, packaging and labelling
Surface treatments must follow the product/definition document. Packaging must protect rivets, contain only one batch (max package mass 25 kg unless specified otherwise) and include a delivery note. Labels must include designation, quantity, manufacturer and batch number.
- Statistical process control (SPC)
ISO 12288 allows substitution of final sampling by SPC if the manufacturer justifies its process control using ISO/TR 13425 and control chart standards (ISO 7966, ISO 7870, ISO 8258).
Practical applications
- Procurement teams use ISO 12288 to write purchase specifications and ensure purchased nickel‑alloy solid rivets meet aerospace requirements.
- Quality and inspection engineers use the standard to design acceptance tests, sampling plans and records for rivet batches.
- Fastener manufacturers use it to structure production, heat treatment, metallurgical testing and marking for compliance.
- Certification authorities and prime contractors use the document to approve suppliers and audit conformance.
Who should use this standard
- Aerospace OEMs and suppliers, fastener manufacturers, procurement engineers, quality assurance personnel, and certification bodies involved in the production, purchase or approval of nickel‑alloy solid rivets.
