ISO R 209-1971 rus PDF

Full title and description

Composition of wrought products of aluminium and aluminium alloys — Chemical composition (per cent). This is the ISO recommendation issued in 1971 (ISO/R 209:1971) that specified chemical-composition limits and related designation practice for wrought aluminium products and alloys; a Russian-language edition/transcription exists under the title St ISO R 209-1971 rus.

Abstract

ISO/R 209:1971 provided tabulated chemical-composition limits expressed in percent for wrought aluminium and aluminium alloys, together with the designation approach used at the time for identifying alloy compositions. The document is a short legacy recommendation that has since been withdrawn and incorporated into later ISO 209 family publications.

General information

• Status: Withdrawn (legacy ISO Recommendation).
• Publication date: 1971 (ISO/R 209:1971).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 77.150.10 — Aluminium and aluminium alloys (wrought products).
• Edition / version: ISO/R edition issued 1971 (ISO recommendation form).
• Number of pages: Very short technical note — typically 1–2 pages in the published paper copy (catalogue entries list 2 pages).

Scope

Defines chemical-composition values (percent by mass) for wrought aluminium products and alloys and establishes designation practice applicable to those compositions as published in ISO/R 209:1971. The recommendation applied to wrought product forms and served as a reference for manufacturers, inspection bodies and standards committees until it was superseded by later parts and consolidated ISO 209 publications.

Key topics and requirements

• Chemical-composition tables for wrought aluminium and wrought alloys (percent by mass).
• Designation rules for indicating alloy chemistry used at the time (basis for later ISO designation guidance).
• Short format legacy recommendation intended as a catalogue/reference note for producers and standards bodies.
• Formation of the basis for subsequent ISO 209 parts and consolidated ISO 209 standards (see revisions and replacements).

Typical use and users

Historic reference for metallurgists, materials engineers, standards librarians and organizations working with wrought aluminium products. Today it is used mainly for historical traceability, cross-referencing older specifications, and understanding the evolution of ISO alloy-designation and composition rules prior to the consolidated ISO 209 series.

Related standards

ISO/R 209:1971 was later replaced and consolidated into the ISO 209 family. Key related documents include ISO 209-1:1989 (Part 1 — chemical composition), subsequent consolidated editions such as ISO 209:2007, and the most recent consolidated ISO 209 editions (ISO 209:2024 and its amendments). For up-to-date chemical composition limits and designation rules refer to the current ISO 209 series.

FAQ

Q: What is this standard?

A: ISO/R 209:1971 is an ISO recommendation titled "Composition of wrought products of aluminium and aluminium alloys — Chemical composition (per cent)". It is a short legacy document that listed chemical-composition limits for wrought aluminium products.

Q: What does it cover?

A: It covers chemical-composition values expressed as percentages for wrought aluminium and aluminium alloys and the designation practice used at the time. It does not provide extensive test methods or mechanical-property tables — those topics are covered in other ISO documents.

Q: Who typically uses it?

A: Historically used by aluminium manufacturers, material engineers, quality/inspection labs and standards committees. Today it is primarily of interest for historical reference, standards research, and cross-referencing older technical documents.

Q: Is it current or superseded?

A: ISO/R 209:1971 has been withdrawn and superseded through the ISO 209 series (for example ISO 209-1:1989, ISO 209:2007) and ultimately by the consolidated ISO 209 editions (latest: ISO 209:2024). Users requiring current chemical-composition limits should consult the current ISO 209 publications.

Q: Is it part of a series?

A: Yes — ISO/R 209:1971 formed an early element of what later became the ISO 209 family addressing chemical composition and product forms for wrought aluminium and alloys; the family has been maintained and updated in later parts and consolidated editions.

Q: What are the key keywords?

A: aluminium, aluminium alloys, wrought products, chemical composition, percent, alloy designation, ISO/R 209.
