TS EN ISO 7369

TS EN ISO 7369 is a vocabulary standard that harmonises the terms used for metal hoses, metal hose assemblies and their component parts in pipework. Standards of this type help designers, suppliers and technical writers use the same terms with the same meaning in drawings, specifications and technical documents.

Core terminology for metal hoses

In general technical use, a metal hose is a flexible element used where a rigid pipe cannot accommodate movement, vibration or alignment variations. A hose assembly is the complete product, typically combining the hose body with end fittings. That distinction matters because the hose, the fittings and any protective or lining layers may each contribute different functional characteristics and naming conventions.

The scope of this document covers stripwound metal hoses and corrugated metal hoses, together with their assemblies. It also notes that these hoses may be braided, covered or lined. This gives a common terminology framework for several structural variants within the same product family.

What this vocabulary standard contributes

• It defines current terms used in the field.
• It clarifies naming for metal hoses, hose assemblies and component parts.
• It provides equivalent terms in English, French, German and Dutch.
• It brings stripwound and corrugated hose types into one terminological system.

More broadly, vocabulary standards reduce ambiguity in engineering communication and support consistent use of terms across design, procurement, maintenance and quality documentation. Because metal hoses are used in general fluid systems and industrial pipework, clear terminology is especially useful when selecting components and describing their construction.
