Full title and description

ISO 1190-1:1982 — Copper and copper alloys — Code of designation — Part 1: Designation of materials. Defines an international system for the designation of copper and copper-alloy materials based on chemical composition limits, using the prefix "ISO", international chemical symbols for base and major alloying elements, letters or numbers to indicate grade/content, and the prefix "G" for cast alloys.

Abstract

This part of ISO 1190 sets rules for forming material designations for wrought and cast coppers and copper alloys. Designations are founded on chemical-composition limits: the prefix "ISO" is applied, the base element and principal alloying elements are shown by chemical symbols, and additional letters or numbers indicate grade or nominal content; cast alloys carry a leading "G". The aim is a concise, internationally consistent designation system for procurement, specification and documentation.

General information

• Status: Published (International Standard — confirmed on periodic review).
• Publication date: 1 November 1982 (Edition 1, 1982-11).
• Publisher: International Organization for Standardization (ISO), developed by ISO/TC 26 (Copper and copper alloys).
• ICS / categories: 77.120.30 — Copper and copper alloys.
• Edition / version: Edition 1 (1982).
• Number of pages: 1 page (concise/technical specification).

Scope

Specifies rules for creating standardized designations for copper and copper-alloy materials intended for international use. The scope covers the format and elements of a designation (prefix, element symbols, grade letters or numeric content indications) and identifies how cast alloys should be distinguished. It does not itself define specific chemical composition limits for every alloy family but prescribes the code-format to be used where composition limits are available.

Key topics and requirements

• Use of the prefix "ISO" for all material designations under this code.
• Designation formation based on chemical-composition limits rather than solely trade names.
• Use of international chemical symbols to identify the base element and major alloying elements.
• Application of letters to indicate metal grade or numbers to indicate nominal alloy content.
• Prefix "G" reserved for cast alloys to distinguish them from wrought forms.
• Intended as a harmonized shorthand for specification, procurement and documentation across countries and organizations.

Typical use and users

Used by standards committees, material specification writers, metallurgists, product designers, purchasers and quality engineers who need concise, unambiguous material identifiers for copper and copper-alloy products in drawings, bills of materials, procurement documents and cross-referencing between national designations. It is primarily a designation/code reference rather than a test or product-delivery standard.

Related standards

Part 2 of the same series (ISO 1190-2:1982) dealt with designation of tempers but has been withdrawn; related family standards include ISO series on copper and copper alloys (for terms and definitions, product forms and delivery conditions) such as ISO 197 (terms/definitions) and product-specific standards like ISO 1634-1 for wrought products. National and regional adaptations and compendia (CEN/CEN-TS and national standards bodies) may also reference ISO 1190-1 for designation practice.

FAQ

Q: What is this standard?

A: ISO 1190-1:1982 is Part 1 of the ISO code of designation for copper and copper alloys; it prescribes how material designations are formed (prefixes, element symbols, grade letters/numbers).

Q: What does it cover?

A: It covers the format and rules for designating copper and copper-alloy materials based on chemical-composition limits, including use of the "ISO" and "G" prefixes and the way to indicate base and alloying elements. It does not enumerate every alloy composition.

Q: Who typically uses it?

A: Standards bodies, material specifiers, metallurgists, designers, purchasers and quality engineers who need harmonized, compact material identifiers for international procurement and documentation.

Q: Is it current or superseded?

A: ISO 1190-1:1982 remains a published international standard and has been subject to periodic review and confirmation; users should check the ISO catalogue or their national body for the current review status before assuming currency for regulatory or contractual use. (Part 2 of the series — designation of tempers — has been withdrawn.)

Q: Is it part of a series?

A: Yes — ISO 1190 is a multi-part code of designation. ISO 1190-1 covers material designation (this document); ISO 1190-2 covered designation of tempers (withdrawn). Other ISO standards covering copper and copper alloys (terms, product delivery conditions and compositions) are commonly used alongside ISO 1190 parts.

Q: What are the key keywords?

A: copper, copper alloys, designation, code of designation, ISO 1190, chemical symbols, material grade, cast alloys (G prefix).
