Full title and description

St ISO 1894-1979 — General purpose series 1 freight containers — Minimum internal dimensions. This short ISO publication specifies the minimum internal lengths, widths and heights for ISO series‑1 general‑purpose freight containers and was published as the 1979 edition of ISO 1894.

Abstract

ISO 1894:1979 defines minimum internal dimensional requirements for series‑1 (ISO) general‑purpose freight containers so that internal usable space and door opening clearances meet a common, internationally agreed baseline. These minimum internal dimensions were later incorporated into the broader Series‑1 container specifications and testing documents.

General information

• Status: Withdrawn / historical.
• Publication date: 1979 (July 1979 edition).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 55.180.10 (General purpose containers).
• Edition / version: 1979 edition (replaced an earlier 1975 edition).
• Number of pages: Very short document (published as a 1‑page technical specification in ISO catalog listings / vendors).

Scope

The standard covers minimum internal length, width and height values for ISO series‑1 general‑purpose freight containers, and the ways those minimums are to be measured (typically at a reference temperature). It was intended to ensure compatibility of internal cargo space across manufacturers and modes of transport; these internal‑dimension requirements were later absorbed into broader ISO container specifications.

Key topics and requirements

• Minimum internal length, width and height values for series‑1 general‑purpose containers.
• Reference conditions and measurement conventions for internal dimensions (e.g., measurement temperature and points to measure to avoid counting projecting fittings).
• Door opening and usable internal space considerations — ensuring minimum clearances for cargo handling and interchangeability.
• Compatibility with series‑1 classification and subsequent container specification standards (so manufacturers and users can plan internal load arrangements consistently).

Typical use and users

Primary users include container designers and manufacturers, freight and logistics engineers, shipper/forwarder specification teams, port and terminal planners, and standards bodies updating container dimensional and testing requirements. The information is typically used when specifying container internal volumes, designing unit loads, and ensuring interchangeability for multimodal transport.

Related standards

ISO 1894:1979 is historically related to and later superseded in practice by the ISO series covering container classification and specifications, notably ISO 1496‑1 (Series 1 freight containers — specification and testing) and ISO 668 (Series 1 freight containers — classification, dimensions and ratings). Other related standards often referenced alongside internal dimensions include ISO 6346 (container marking) and ISO 1161 (corner fittings).

FAQ

Q: What is this standard?

A: ISO 1894:1979 specifies minimum internal dimensions for ISO series‑1 general‑purpose freight containers — a short technical specification published by ISO in 1979.

Q: What does it cover?

A: It covers the minimum internal length, width and height values and the conventions for measuring those internal dimensions so that containers manufactured to ISO series‑1 designations provide consistent usable internal space.

Q: Who typically uses it?

A: Container manufacturers, shipping and logistics specifiers, port/terminal planners, and standards committees concerned with container dimensional compatibility and unit‑load planning.

Q: Is it current or superseded?

A: ISO 1894:1979 has been withdrawn as a standalone document. Its internal‑dimension content was incorporated into later, broader container specifications (notably ISO 1496‑1 for series‑1 containers) and into the series/classification documents (ISO 668). It is therefore a historical/withdrawn standard and not the current source for container specifications.

Q: Is it part of a series?

A: Yes — ISO 1894 addressed minimum internal dimensions for the ISO series‑1 family of freight containers and is linked to the family of standards maintained by ISO/TC 104 (series/classification, specifications and testing such as ISO 668 and ISO 1496‑1).

Q: What are the key keywords?

A: Minimum internal dimensions, series‑1, freight containers, ISO 1894, container dimensions, interchangeability, ISO/TC 104.
