Full title and description

ISO 1023:1974 — Aircraft — High pressure air charging valves. Specifies coupling dimensions, access clearances, basic valve dimensions and the coupling-end screw thread; valves are given in tabulated forms. Russian-language PDF editions and translations are available from standards distributors.

Abstract

This international standard (first edition, 1974) defines the dimensional and interfacing requirements for high-pressure air charging valves used on aircraft, including required coupling dimensions, access clearances, basic valve geometry and the screw thread at the coupling end; characteristic data are presented in tables. The document was published in 1974 and later withdrawn from the ISO catalogue.

General information

• Status: Withdrawn (withdrawal recorded in the ISO catalogue).
• Publication date: July 1974 (1974-07).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 49.080, 49.100 (aircraft equipment and ground support).
• Edition / version: Edition 1 (1974).
• Number of pages: ISO catalogue lists 2 pages for the published International Standard; some distributor copies (including Russian-language editions) show 4 pages (cover/translation variations).

Scope

Applies to high-pressure air charging valves used on aircraft and to the associated coupling interfaces. The standard sets dimensional requirements for the valve body and the access clearance to be provided in aircraft installations, specifies the screw thread at the coupling end and presents the valve types and sizes in tables so manufacturers and airframe designers can ensure mechanical interchangeability and safe access for ground charging equipment.

Key topics and requirements

• Coupling dimensions and mating clearances required for high-pressure charging connections.
• Basic valve overall dimensions and recommended access clearance around the valve.
• Specification of the screw thread form and dimensions at the coupling end.
• Tabulated valve types, sizes and key dimensional data for manufacturer and maintenance reference.
• Intended to ensure mechanical compatibility between aircraft-installed valves and ground charging equipment.

Typical use and users

Used by aircraft designers, systems engineers, component and valve manufacturers, maintenance, repair and overhaul (MRO) organizations, ground support equipment manufacturers and regulatory/airworthiness authorities when specifying, producing or servicing high-pressure air charging valves and their interfaces. Russian-language or translated PDFs are used by Russian-speaking stakeholders and distributors.

Related standards

Related documents include other ISO standards and industry specifications for aircraft ground support connections and pneumatic fittings, and additional ISO aircraft equipment standards produced by ISO/TC 20 and its subcommittees. National adoptions or translations (including Russian editions) and supplier-specific data sheets are often used alongside ISO 1023:1974 for procurement and installation details.

FAQ

Q: What is this standard?

A: ISO 1023:1974 is an International Standard that defined the dimensional and interfacing requirements for aircraft high-pressure air charging valves (first edition, published July 1974).

Q: What does it cover?

A: It covers coupling dimensions, required access clearance, basic valve dimensions, the screw thread at the coupling end and tabulated valve data to ensure mechanical interchangeability between aircraft valves and ground charging equipment.

Q: Who typically uses it?

A: Aircraft designers and systems engineers, valve and ground-equipment manufacturers, MRO organizations, and airworthiness/regulatory authorities; translated or Russian PDF editions are used by Russian-speaking stakeholders and distributors.

Q: Is it current or superseded?

A: The ISO catalogue lists ISO 1023:1974 as Withdrawn. The ISO entry does not list a direct replacement in the catalogue entry; users should check the latest ISO catalogue or relevant national adoption for any successor documents before relying on the withdrawn standard in new designs.

Q: Is it part of a series?

A: It is an ISO aircraft-equipment standard prepared under ISO/TC 20 (aircraft) and its subcommittees; while not a multi-part series itself, it is related to other ISO standards addressing aircraft fittings, connections and ground-support interfaces.
