Full title and description

ISO 1000:1992/Amd 1:1998 — SI units and recommendations for the use of their multiples and of certain other units (Amendment 1). This 1998 amendment updates the 1992 ISO 1000 edition with short technical changes and recommendations relating to the presentation and use of SI units, their multiples and certain other commonly used units.

Abstract

This document is Amendment 1 to ISO 1000:1992. It is a brief (2-page) amendment that makes targeted updates to the International Standard on SI units and recommendations for the use of their multiples and of certain other units. The amendment was published in November 1998 and has since been withdrawn and incorporated into later consolidated standards (notably ISO 80000 series).

General information

• Status: Withdrawn.
• Publication date: November 1998 (Amendment published 1998-11).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 01.060 (Quantities and units).
• Edition / version: Edition 3 — Amendment 1 (1998).
• Number of pages: 2 pages.

Scope

This amendment applies to ISO 1000:1992 and provides concise changes and recommendations related to the International System of Units (SI), guidance on the use of multiples and prefixes, and the treatment of certain other units used alongside SI. It is intended to clarify and correct specific points of usage in the parent standard; the amendment itself is short and was later withdrawn as its content was incorporated into subsequent consolidated standards in the ISO 80000 series.

Key topics and requirements

• Clarifications to recommended usage of SI units and their symbols.
• Updates or corrections to prefixes and multiples for SI units.
• Guidance on use of certain other (non-SI) units in conjunction with SI.
• Editorial/technical amendments intended to align ISO 1000 with evolving practice prior to consolidation into ISO 80000-series standards.

Typical use and users

Used by national standards bodies, metrologists, technical editors, engineers, scientific publishers, educators, and organisations that require authoritative guidance on unit notation and the correct use of SI units and multiples. Because the amendment is withdrawn, users requiring current rules should consult the ISO 80000-1 series (and later revisions) for up-to-date requirements.
