Full title and description
ISO 1023:1974 — Aircraft — High pressure air charging valves. This International Standard specifies the basic dimensions, coupling details and access clearances for high-pressure air charging valves used on aircraft.
Abstract
The standard defines coupling dimensions, the required access clearance and the screw thread at the coupling end for aircraft high-pressure air charging valves. It presents the valve basic dimensions and provides tabulated values for the specified valve types. The original publication is a short technical specification (2 pages).
General information
- Status: Withdrawn (original edition published 1974; formal withdrawal recorded in ISO life cycle).
- Publication date: July 1974 (Edition 1, 1974-07).
- Publisher: International Organization for Standardization (ISO).
- ICS / categories: 49.080, 49.100 (aircraft equipment and related categories).
- Edition / version: Edition 1 (ISO 1023:1974).
- Number of pages: 2 pages (short technical standard).
Scope
Specifies the geometry and interfacing details for aircraft high-pressure air charging valves: the basic valve dimensions, the required access clearance around the valve, the thread form and dimensions at the coupling end, and tabulated nominal sizes for the valve family. The intent is to ensure mechanical interchangeability and proper access for charging operations on aircraft systems.
Key topics and requirements
- Defined basic dimensions for valve bodies and couplings to ensure interchangeability.
- Specified access clearance requirements to allow safe connection/disconnection and maintenance.
- Thread requirements at the coupling end (screw thread form and dimensions) for secure fittings.
- Tabulated valve sizes and dimensional tolerances for the range covered by the standard.
- Provision for compatibility with aircraft charging equipment and procedures.
Typical use and users
Used historically by aircraft designers, hydraulic/pneumatic systems engineers, maintenance organizations, component manufacturers and procurement specialists involved with aircraft high-pressure charging systems. Although the 1974 edition is withdrawn, historical copies can inform legacy system maintenance, part replacement decisions and verification of older equipment conformity.

FAQ
Q: What is this standard?
A: ISO 1023:1974 is an International Standard titled "Aircraft — High pressure air charging valves" that specifies dimensions, coupling details and access clearances for aircraft high-pressure air charging valves.
Q: What does it cover?
A: It covers the basic valve and coupling dimensions, the required access clearance for charging operations, the screw thread at the coupling end, and tabulated valve sizes and tolerances to enable mechanical interchangeability.
Q: Who typically uses it?
A: Aircraft designers, systems and maintenance engineers, manufacturers of aircraft valves and charging equipment, and procurement/specification teams involved with aircraft pneumatic systems — particularly when dealing with legacy equipment that cites the 1974 specification.
Q: Is it current or superseded?
A: The 1974 edition of ISO 1023 is recorded as Withdrawn in the ISO lifecycle; it is not an active current standard. For contemporary design and certification requirements, users should consult the ISO catalogue and current standards from ISO/TC 20 or relevant aviation authorities.
Q: Is it part of a series?
A: ISO 1023:1974 is a standalone International Standard addressing a specific aircraft component type. Related documents exist within the body of ISO standards for aircraft equipment and pneumatic fittings, but ISO 1023 itself is a single-part standard (Edition 1, 1974).
Q: What are the key keywords?
A: Aircraft, high-pressure charging valve, coupling dimensions, access clearance, valve thread, interchangeability, ISO 1023:1974.
