Full title and description
ISO 24568:2021 — Aerospace — Metric series pipe coupling 8°30' up to 28 000 kPa dynamic beam seal — Technical specification. Specifies a technical specification for metric-series 8°30′ dynamic beam-seal pipe couplings intended for aerospace applications, including required characteristics and procurement requirements.
Abstract
This document specifies the required characteristics, inspection and test methods, quality assurance and procurement requirements for metric series 8°30′ dynamic beam seal pipe couplings for temperature ranges Type II and III (as defined in ISO 6771) and for nominal pressure up to 28 000 kPa. It covers materials, dimensions, marking, surface condition, threads and acceptance/inspection methods.

Scope
ISO 24568:2021 applies to metric-series pipe couplings with an 8°30′ dynamic beam seal used in aerospace fluid systems where rated nominal pressure does not exceed 28 000 kPa and where temperature ranges correspond to Type II and Type III as defined by ISO 6771. The standard sets out product characteristics, inspection and test methods, quality assurance and procurement requirements to ensure interchangeability and performance in service.
Key topics and requirements
- Definition of the metric-series 8°30′ dynamic beam-seal coupling geometry and dimensional tolerances.
- Material requirements and conformity documentation (material certificates/chemical analysis requirements).
- Inspection and test methods: dimensional checks, fluid passage verification, surface roughness, visual inspection for defects, thread examination and applicable non‑destructive testing.
- Surface treatment, marking and batch identification requirements for traceability.
- Quality assurance and acceptance criteria for qualification and routine inspection (qualification and acceptance sampling where applicable).
- Requirements referenced to related standards for temperature classification and surface/specification references (e.g., ISO 6771 for temperature types, and common reference practices for surface roughness and material certificates).
Primary technical coverage and test/inspection examples are described in the main text and in tabulated requirement-to-test mappings.
Typical use and users
Used by aerospace component manufacturers, suppliers of fluid system fittings and couplings, quality and procurement teams in aerospace OEMs and MRO organisations, engineering design teams specifying fluid-system hardware, and conformity/inspection laboratories performing acceptance testing. The standard is intended for procurement specifications, design verification and supplier quality control.
Related standards
Standards commonly referenced alongside ISO 24568:2021 include ISO 6771 (temperature classification for couplings/seals), standards for material certification (e.g., EN ISO 10204 formats), surface specification standards such as ISO 1302, and other ISO/TC 20/SC 10 deliverables for aerospace fittings and fluid systems. Users should check those referenced documents for normative requirements.

FAQ
Q: What is this standard?
A: ISO 24568:2021 is an international technical specification that defines the requirements, inspection and test methods, and procurement/quality requirements for metric-series 8°30′ dynamic beam-seal pipe couplings used in aerospace fluid systems.
Q: What does it cover?
A: It covers component characteristics (materials, dimensions, threads, surface condition), inspection and testing procedures (dimensional checks, fluid passage verification, surface roughness, visual and non‑destructive inspection), marking and traceability, and acceptance criteria up to nominal pressures of 28 000 kPa and for specified temperature ranges.
Q: Who typically uses it?
A: Aerospace manufacturers and suppliers of couplings and fittings, design engineers, procurement and quality teams at OEMs and maintenance organisations, and test/inspection laboratories. It is used to define procurement specs and to verify conformance of delivered parts.
Q: Is it current or superseded?
A: As published on 12 July 2021, ISO 24568:2021 is the current edition (Edition 1). Users should consult ISO or their national standards body for any subsequent confirmations, amendments, reviews or revisions.
Q: Is it part of a series?
A: The document sits within ISO/TC 20/SC 10 work on aerospace fittings and fluid-system components and references related ISO documents (for example ISO 6771 for temperature classification). It should be considered alongside related aerospace component standards rather than as a standalone series.
