ISO 6361-1:2011

Overview

ISO 6361-1:2011 defines the technical conditions for inspection and delivery of wrought aluminium and aluminium-alloy sheets, strips and plates for general engineering applications. It applies to flat‑rolled products with a thickness over 0.15 mm up to and including 400 mm. The standard covers ordering, inspection lots, sampling, testing and delivery documentation, but explicitly excludes semi‑finished coiled reroll stock and special applications such as aerospace, can stock or fin stock.

Key search terms: ISO 6361-1, wrought aluminium sheets, aluminium strips, plates, inspection and delivery, flat‑rolled products.

Key Topics

• Scope and product definitions: clear definitions for sheet, strip and plate, inspection lots, heat‑treatment batches, samples and test pieces.
• Orders and tenders: information suppliers and purchasers must record - alloy designation, form, temper, dimensions, tolerances, quantity and any certificate/test requirements.
• Production and quality control: supplier responsibility for required inspections and tests prior to shipment; buyer option to inspect at works.
• Chemical composition and mechanical properties: chemical limits referenced to ISO 6361‑5; mechanical property requirements referenced to ISO 6361‑2 or as agreed in the order.
• Corrosion behaviour: requirements and test references for specific alloy/temper combinations (e.g., ASTM and ISO corrosion tests indicated for 5XXX, 7XXX and certain plate tempers).
• Surface finish and dimensional tolerances: products must be free from defects detrimental to use; tolerances per ISO 6361‑3 (strip) and ISO 6361‑4 (sheet/plate).
• Sampling and test procedures: specimen orientation (transverse preferred; longitudinal allowed if width < 300 mm), sampling at casting for chemical analysis, specimen marking, preparation and retest rules.
• Inspection documents and delivery: certificates of conformity, test reports, marking, packing and arbitration test provisions.

Applications and Users

Who uses ISO 6361-1:

• Aluminium sheet/strip/plate manufacturers and mill quality managers
• Procurement and specifications engineers in general engineering
• Inspection and testing laboratories preparing conformity certificates
• Suppliers and purchasers negotiating orders and tolerances

Practical benefits:

• Standardizes order content, sampling and test procedures
• Reduces disputes at delivery via defined inspection documents and arbitration tests
• Ensures traceability of heat treatments, composition and mechanical performance for general engineering uses

Related Standards

• ISO 6361 series: Part 2 (mechanical properties), Part 3 (strips tolerances), Part 4 (sheets/plates tolerances), Part 5 (chemical composition)
• Test standards referenced: ISO 6892‑1 (tensile), ISO 7438 (bend), ISO 9591/11881 and various ASTM corrosion and chemical analysis methods

Use ISO 6361-1 when specifying or accepting wrought aluminium flat products for consistent inspection, testing and delivery practices in general engineering contexts.
