ISO 10380:2012

Overview

ISO 10380:2012 - Pipework: Corrugated metal hoses and hose assemblies - specifies the minimum requirements for design, manufacture, testing and installation of corrugated metal hoses and metal hose assemblies. The third edition (2012) is a base international standard intended to ensure safe, long-term operation of pressure‑tight corrugated metal hoses (helical or annular corrugations) and their assemblies when properly installed and used under typical chemical, mechanical and thermal conditions.

Keywords: ISO 10380:2012, corrugated metal hose, metal hose assemblies, pipework standard, hose testing, design requirements.

Key Topics

• Scope and definitions: establishes terms such as corrugated metal hose, nominal size (DN), nominal pressure (PN), maximum allowable pressure (PS), active live length and test pressure.
• Design requirements: covers materials, hose profile (helical “h” or annular “a”), nominal sizes, overall/active live length, braiding, attachments and end fittings, additional protection and electrical conductivity.
• Performance requirements and tests: leaktightness, pressure resistance, elongation, burst pressure, pliability, fatigue (fatigue life classifications: type 1-50, 1-10, 2-10, 3), and electrical conductivity testing.
• Operating limits: guidance on pressure, temperature and corrosion considerations; flow velocity and cleanliness requirements.
• Conformity and certification: procedures for initial and subsequent type testing, factory production control (FPC), third‑party conformity assessment and final assessment.
• Installation and marking: instructions for installation, packaging, designation and marking of hose assemblies.

Applications

ISO 10380:2012 is relevant for applications where flexible metal hoses are required to accommodate movement, vibration, thermal expansion, or to provide pressure‑tight connections. Typical uses include:

• Industrial process piping and plant equipment
• HVAC and steam systems
• Chemical and petrochemical installations
• Power generation and marine systems
• Any system requiring braided or unbraided corrugated metal hoses for pressure containment

Who uses this standard:

• Designers and engineers specifying hose assemblies
• Manufacturers and assemblers of corrugated metal hoses and end fittings
• Test laboratories and quality managers implementing FPC and conformity assessment
• Suppliers, installers and importers ensuring compliance and safe installation
