Full title and description

ISO 1022:1988 — Aerospace — Gaseous oxygen replenishment connection for use in fluid systems (old type) — Dimensions (Inch series). Defines mating dimensions and required access clearance for an older style of gaseous-oxygen replenishment coupling intended for aerospace fluid systems; marked as not applicable to new designs.

Abstract

This International Standard specifies the mating dimensions, thread form, plugging of orifice and the access clearances for the older (inch-series) gaseous-oxygen replenishment connection used in aerospace fluid systems. The document is brief (3 pages) and is intended to provide dimensional interchangeability for maintenance and legacy equipment; it is not applicable for new designs and was later superseded.

Scope

Specifies dimensional requirements and access clearances for the older inch-series gaseous-oxygen replenishment coupling used in aerospace fluid systems. The standard covers mating dimensions, thread details and provisions for plugging of the orifice to ensure correct mating and safe serviceability of legacy equipment; it explicitly states it is not applicable for use in new designs.

Key topics and requirements

• Defined mating dimensions for coupling components (inch-series).
• Specification of thread form and fit for mating parts.
• Requirements for plugging orifices and ensuring access clearance for service/inspection.
• Dimensional tolerances and interchangeability requirements for legacy aerospace oxygen replenishment connections.
• Statement limiting applicability — not valid for new designs (for new designs, users are directed to the superseding standard).

Typical use and users

This standard was primarily used by aerospace manufacturers, maintenance and repair organizations, aircraft operators maintaining legacy fleets, design engineers working on retrofits or spares for older systems, and standards/quality engineers responsible for parts interchangeability in oxygen fluid systems.

Related standards

ISO 1022:1988 was later withdrawn and revised by ISO 8775:1988; users working on new designs or seeking currently applicable requirements should refer to the superseding document and other current aerospace oxygen-system standards.

FAQ

Q: What is this standard?

A: ISO 1022:1988 is an International Standard that specified the dimensional and design details for an older (inch-series) gaseous-oxygen replenishment connection used in aerospace fluid systems.

Q: What does it cover?

A: It covers mating dimensions, thread particulars, plugging of the orifice and access clearances needed to ensure proper mating and serviceability of the specified older connector type; it does not apply to new designs.

Q: Who typically uses it?

A: Organizations maintaining or supplying parts for legacy aerospace systems — aircraft OEMs working with legacy components, maintenance/repair facilities, operators of older fleets, and standards/quality engineers concerned with interchangeability and spares.

Q: Is it current or superseded?

A: The standard is withdrawn (published January 1988, Edition 1) and was revised by ISO 8775:1988; it is not current for new designs.

Q: Is it part of a series?

A: It is an aerospace equipment standard produced under ISO/TC 20/SC 10 and is related to other ISO standards addressing oxygen system components and coupling dimensions; ISO 8775:1988 is the direct successor for updated requirements.

Q: What are the key keywords?

A: Aerospace, gaseous oxygen, replenishment connection, coupling dimensions, inch series, mating dimensions, access clearance, legacy connector.
