Full title and description

ISO 1034:1973 — Aircraft — Ground air-conditioning connections. This International Standard specifies dimensional and functional requirements for aircraft-mounted connections used to receive air-conditioning from ground sources, defining connection sizes, basic dimensions and limits on projection beyond the sealing plane.

Abstract

Gives the requirements for 127 mm (5 in) and 203 mm (8 in) connections for the purpose of air-conditioning from ground sources. The connections comply with the basic dimensional requirements shown in the applicable figures; the ground unit must not project more than 14.0 mm beyond the sealing plane except through defined openings.

Scope

This standard applies to external aircraft connections intended for supplying conditioned (air‑conditioning) air from ground units. It specifies two nominal connection sizes (127 mm and 203 mm), the basic dimensional forms (as shown in the figures of the standard), and limits on projection of the ground unit relative to the aircraft sealing plane to ensure interchangeability and safe ground handling. ISO 1034:1973 replaces ISO/R 10:1955.

Key topics and requirements

• Two standardized connection sizes: 127 mm (5 in) and 203 mm (8 in) for aircraft ground air‑conditioning interfaces.
• Basic dimensional requirements and two figure options for connection geometry to ensure mating compatibility.
• Maximum allowed projection of ground unit components beyond the aircraft sealing plane (14.0 mm) except through defined openings.
• Requirement for mechanical compatibility between aircraft-mounted fittings and ground equipment to support safe ground conditioning operations.
• Reference to prior ISO/R 10:1955 as the document superseded by this standard.

Typical use and users

Used by aircraft manufacturers and designers, ground support equipment (GSE) manufacturers, airline maintenance organizations, airport ground handling providers and regulatory bodies concerned with ground-air interface safety and interchangeability. The standard is typically consulted when specifying or procuring aircraft air‑conditioning inlet fittings, designing ground conditioning units, or validating compatibility during aircraft modification and maintenance.

Related standards

ISO 1034:1973 replaces ISO/R 10:1955. It is related to other ground support equipment and aircraft interface standards (for example, national and regional standards on aircraft ground support equipment safety and interfaces). National bodies and standards catalogues list ISO 1034 alongside relevant GSE standards such as EN standards for aircraft ground support equipment.

FAQ

Q: What is this standard?

A: ISO 1034:1973 is an International Standard that defines standardized external connections on aircraft for receiving conditioned air from ground sources (ground air‑conditioning connections).

Q: What does it cover?

A: It covers the dimensional and basic functional requirements for two nominal connection sizes (127 mm and 203 mm), the permitted configuration forms (as shown in the figures), and limits on projection of ground units beyond the aircraft sealing plane to ensure compatibility and safe operation.

Q: Who typically uses it?

A: Aircraft manufacturers, GSE manufacturers, airlines, airport ground handlers, maintenance organizations and conformity assessors use the standard when designing, procuring or verifying aircraft/ground air‑conditioning interfaces.

Q: Is it current or superseded?

A: ISO lists ISO 1034:1973 as published and periodically reviewed; the edition published in June 1973 (Edition 1) was reviewed and confirmed in ISO's periodic review process (confirmed in recent reviews), so the 1973 text remains the current edition unless a newer edition is published.

Q: Is it part of a series?

A: ISO 1034 is not presented as a multi‑part series; it superseded the earlier ISO/R 10:1955. It falls under the purview of ISO/TC 20/SC 9 (aircraft ground support and servicing interfaces) and is related to other standards addressing ground service equipment and aircraft interfaces.

Q: What are the key keywords?

A: Aircraft, ground air‑conditioning connections, 127 mm, 203 mm, sealing plane, ground support equipment, ISO 1034:1973.
