Wrought aluminium and aluminium alloys - Sheets, strips and plates - Part 4: Sheets and plates: Tolerances on shape and dimensions

ISO 6361-4:2014 specifies the tolerances on shape and dimensions for wrought aluminium and aluminium alloy sheet and plate by hot-rolling or cold-rolling for general engineering applications. It applies to products with a thickness over 0,15 mm up to and including 203 mm. It does not apply to semi-finished rolled products in coiled form to be subjected to further rolling (reroll stock) or to special products, such as those that are corrugated or embossed. Technical conditions for inspection and delivery of products covered by ISO 6361-4:2014 are specified in ISO 6361‑1.

Overview

ISO 6361-4:2014 - "Wrought aluminium and aluminium alloys - Sheets and plates: Tolerances on shape and dimensions" - defines dimensional and shape tolerances for hot-rolled and cold-rolled aluminium sheet and plate for general engineering applications. The standard applies to products with a thickness > 0.15 mm and ≤ 203 mm, and excludes reroll stock (coiled semi‑finished products) and special forms (corrugated, embossed). Technical conditions for inspection and delivery are specified in ISO 6361‑1.

Key topics and technical requirements

• Thickness tolerances: Detailed tabulated tolerances for cold-rolled and hot-rolled products (see Tables 1–4). Values depend on alloy group, specified thickness and width. Note: when a tolerance is given as an "all plus" or "all minus" side, the numerical value is doubled.
• Width tolerances: Separate limits for sheared and sawed sheet/plate (Tables 5–6). Width is measured at room temperature during cutting.
• Length tolerances: Separate limits for sheared and sawed sheet/plate (Tables 7–8). Length is measured at room temperature during cutting.
• Shape tolerances: Requirements for lateral curvature, flatness and squareness are provided (Section 4), including flatness tolerances and permissible lateral curvature.
• Temperature correction: Measurement dimensional allowance of 0.23 mm per 1 000 mm for a 10 °C deviation from the reference temperature (20 °C).
• Scope limits: Tolerances outside the published ranges (thickness/width) must be agreed between purchaser and supplier.
• Application note: Hot‑rolled tables reference products in temper grade H112 and those finished in hot‑rolled condition.

Practical applications

• Use ISO 6361-4 to specify acceptance criteria in purchase orders and technical drawings for aluminium sheets and plates.
• Apply the tolerances in quality control, incoming inspection, and vendor qualification to ensure parts meet dimensional and flatness requirements.
• Support manufacturing process control (rolling, cutting, sawing) and downstream operations (forming, machining, assembly) by providing consistent dimensional baselines.
• Relevant in industries such as aerospace, automotive, marine, building and construction, and general engineering where predictable dimensional performance of aluminium sheet/plate is required.

Who uses this standard

• Aluminium mill producers and processors
• Purchasing and procurement teams specifying material
• Quality inspectors and metrology labs
• Design and mechanical engineers specifying tolerances
• Fabricators, stampers and finishers who require consistent feedstock

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
