ISO 2119-1972 PDF

Full title and description

ISO 2119:1972 — Magnesium‑zinc‑zirconium alloy castings — Chemical composition. This International Standard specified the permitted chemical composition for castings made from magnesium‑zinc‑zirconium alloys.

Abstract

Short (one‑page) specification published in February 1972 that defined chemical‑composition limits for magnesium‑zinc‑zirconium castings. The standard was later withdrawn and its subject matter incorporated into a subsequent ISO standard (ISO 3115:1981) that extended the scope to include mechanical properties.

General information

• Status: Withdrawn / Annulled (withdrawal of the International Standard).
• Publication date: February 1972 (Edition 1).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 77.150.20; 77.150.60 (magnesium products; lead, zinc and tin products).
• Edition / version: Edition 1 (1972).
• Number of pages: 1 page.

Scope

Specified chemical composition requirements for castings produced from magnesium alloys containing zinc and zirconium. The scope was narrowly focused on compositional limits for specific alloy grades used in castings rather than on dimensional, processing or broad mechanical requirements; those broader items were addressed in later revisions and related standards.

Key topics and requirements

• Permitted ranges and maximums for primary alloying elements (magnesium, zinc, zirconium) and principal impurities.
• Definition of alloy designations and identification for castings made from Mg‑Zn‑Zr systems.
• Requirements for verification of chemical composition (sampling and test pieces as referenced by related ISO methods).
• Reference to committee practice and harmonization with subsequent ISO standards that combined composition with mechanical property limits.

Typical use and users

Used historically by foundries, material and metallurgical engineers, product designers, quality and compliance teams in industries specifying magnesium castings (automotive, aerospace, consumer products). Today it is primarily of archival or historical interest because its content has been superseded by later ISO standards.

Related standards

Primary successor: ISO 3115:1981 (Castings in magnesium alloys containing zirconium — Chemical composition and mechanical properties), which incorporated and expanded the content of ISO 2119:1972. Later revisions covering magnesium alloy castings include ISO 16220 series. Relevant test and reference standards (e.g., ISO 2377 for reference test bars) are also associated.

FAQ

Q: What is this standard?

A: ISO 2119:1972 is an International Standard that specified the chemical composition of magnesium‑zinc‑zirconium alloy castings. It was a short (one‑page) specification published by ISO in February 1972.

Q: What does it cover?

A: It covered permitted chemical composition limits and alloy designation for castings in magnesium‑zinc‑zirconium systems (i.e., which elements and maximum/minimum contents apply to specified casting grades). Broader mechanical property requirements were not the primary focus of this short standard.

Q: Who typically uses it?

A: Historically, foundries, metallurgists, quality engineers and product designers working with magnesium castings used the standard to specify and verify alloy composition. Since it has been withdrawn, practitioners now refer to its successors for current requirements.

Q: Is it current or superseded?

A: It is withdrawn (no longer current). The content was superseded by ISO 3115:1981, which in turn has later been revised/replaced by subsequent standards in the ISO series for magnesium alloys.

Q: Is it part of a series?

A: Yes — it falls within ISO technical work on magnesium and light‑metal alloys (ISO/TC 79/SC 5). Its subject matter was rolled into ISO 3115 and later into ISO 16220 series and related documents that together cover composition, designation and mechanical properties for magnesium castings.

Q: What are the key keywords?

A: Magnesium, zinc, zirconium, alloy, castings, chemical composition, ISO 2119, ISO 3115, withdrawn.
