Aircraft - Ground air-conditioning connections
Gives the requirements for 127 mm and 203 mm connections for the purpose of air-conditioning from ground sources. The conncetions shall comply with the basic dimensional requirements shown in either figure 1 or figure 2 as appropriate. The ground unit must not project more than 14,O mm beyond the sealing plane except through defined openings.

Overview
ISO 1034:1973 specifies mechanical requirements for aircraft ground air‑conditioning connections. It covers the two standard coupling sizes used to supply air‑conditioning from ground sources to aircraft: 127 mm (5 in) and 203 mm (8 in) connections. The standard defines the basic dimensional requirements (shown in Figures 1 and 2 of the document), sealing‑plane limits and interface features to ensure safe, repeatable mating between aircraft receptacles and ground support equipment (GSE).
Key topics and requirements
- Connection sizes: Defines the two nominal couplings - 127 mm and 203 mm - with their basic interface geometry described in the standard figures.
- Dimensional conformity: Aircraft connection openings and sealing areas must comply with the basic dimensions shown in the applicable figure (Figure 1 for 127 mm, Figure 2 for 203 mm).
- Sealing plane and projection limit: The ground unit must not project more than 14.0 mm (0.55 in) beyond the sealing plane except through defined openings, protecting aircraft skin and seal integrity.
- Mechanical engagement: Details bayonet/claw engagement characteristics (including clearance and engagement sectors) to ensure reliable coupling and alignment; bayonet faces may be located symmetrically within a ±30° sector relative to the transverse center line.
- Clearance and bolt/claw provisions: Specifies minimum clearances for ground units and sealing areas, opening diameters, and locations for bolts or claws to secure the connection.
Applications
ISO 1034 is essential for ensuring interoperability and safety where aircraft receive conditioned air from ground units. Typical uses:
- Design and manufacture of aircraft air‑conditioning inlet fittings and doors.
- Specification and production of ground support equipment (GSE) hose connections, adapters and couplings.
- Maintenance, inspection and repair procedures for aircraft environmental control system (ECS) interfaces.
- Procurement and quality control: ensuring supplier parts match standardized aircraft interfaces.
- Airports, airlines and MROs use the standard to ensure compatibility between diverse fleets and GSE vendors.
Who uses this standard
- Aircraft OEMs and component designers
- GSE manufacturers and suppliers
- Airline engineering and maintenance teams
- Airport technical operations and ground handling providers
- Regulatory and certification authorities focusing on aircraft ground interfaces
Related standards (general)
For complete integration, users typically consult other ISO and industry standards covering aircraft connectors, ground support equipment interfaces, environmental control systems and general coupling/dimension standards. Refer to ISO technical committees and aviation guidance for current related documents.

IS0 (the International Organization for Standardization) is a worldwide federation
of national standards institutes (IS0 Member Bodies). The work of developing
International Standards is carried out through IS0 Technical Committees. Every
Member Body interested in a subject for which a Technical Committee has been set
up has the right to be represented on that Committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the Technical Committees are circulated
to the Member Bodies for approval before their acceptance as International
Standards by the IS0 Council.
Prior to 1972, the results of the work of the Technical Committees were published
as IS0 Recommendations; these documents are now in the process of being
transformed into International Standards. As part of this process, International
Standard IS0 1034 replaces IS0 Recommendation R 1034-1969 drawn up by
Technical Committee lSO/TC 20, Aircraft and space vehicles.
The Member Bodies of the following countries approved the Recommendation :
Belgium Greece Switzerland
