Overview
EN ISO 7369:2020 - Pipework: Metal hoses and hose assemblies - Vocabulary is the harmonized CEN/ISO vocabulary for metal hoses used in pipework. The standard defines current terms for metal hoses, metal hose assemblies and their component parts. It applies specifically to:
- Stripwound metal hoses and hose assemblies, and
- Corrugated metal hoses and hose assemblies.
Notes clarify that these hoses may be braided, covered or lined, and Annex A provides equivalent terminology in English, French, German and Dutch. EN ISO 7369:2020 supersedes the 2004 edition and reflects technical updates and new definitions.
Key topics
This vocabulary standard establishes unambiguous definitions used across design, manufacture, testing and procurement of metal hose systems. Core terms include:
- metal hose, stripwound metal hose, corrugated metal hose
- metal hose assembly, end fitting, ferrule, attachment
- Size and pressure designations: nominal size (DN), nominal pressure (PN), design pressure, maximum allowable pressure, maximum operating pressure
- Performance and testing terms: burst pressure, test pressure
- Mechanical attributes: flexibility, pliability, bend radius, minimum bend radius
- Construction and protection: strip, packing, profile, pitch of hose profile, braid, metal braid strand, external/internal protection, coiling
The document also introduces or revises definitions for items such as design pressure, metal braid strand, braided braid, and nominal size of metal hose assembly, and updates guidance on temperature-related definitions.
Applications
EN ISO 7369:2020 is a foundational reference wherever clear, consistent terminology is needed for metal hose systems:
- Technical specifications and product datasheets for metal hoses and hose assemblies
- Engineering design and pipework documentation for industrial fluids, HVAC, chemical plants, power stations and marine systems
- Manufacturing, quality control and testing procedures (to ensure consistent interpretation of test and design pressures)
- Procurement and contract language to avoid ambiguity in orders and compliance checks
- Standards writers and regulatory bodies aligning national standards with ISO/CEN terminology
Who uses this standard
- Hose and fitting manufacturers and suppliers
- Mechanical, piping and process engineers
- Test laboratories and inspection bodies
- Standards committees and technical writers
- Procurement and maintenance teams specifying hose assemblies
Related standards
- ISO 7369:2020 is an ISO International Standard adopted by CEN as EN ISO 7369:2020 and replaces the 2004 edition. For related dimension and pressure conventions, users should reference the normative standards cited in sector-specific documents (e.g., ISO 6708 for DN and ISO 7268 for PN references). Annex A in EN ISO 7369:2020 provides multilingual term equivalents for cross-border projects.
