Overview - EN ISO 10380:2012 (Pipework - Corrugated metal hoses and hose assemblies)
EN ISO 10380:2012 specifies the minimum requirements for the design, manufacture, testing and installation of corrugated metal hoses and metal hose assemblies. Prepared under CEN in collaboration with ISO, this standard establishes a harmonized baseline for materials, construction, performance testing and conformity assessment for pressure‑tight corrugated hoses (helical or annular) and their assemblies.
Key topics and technical requirements
The standard covers technical subjects needed to ensure safe, reliable corrugated metal hoses and hose assemblies:
- Scope and definitions - standardized terms (e.g., corrugated metal hose, DN nominal size, metal hose assembly).
- Design requirements - requirements for nominal sizes, overall length, hose geometry (helical/annular), materials, braiding, and end fittings.
- Material and fabrication - referenced material specifications and welding/brazing qualification standards.
- Operational limits - pressure, temperature, corrosion considerations, flow velocity, and electrical conductivity.
- Protection and joining - additional protection measures, hose joining and attachment of end fittings.
- Performance tests - mandatory tests such as leaktightness, pressure resistance, burst pressure, elongation, pliability, fatigue and electrical continuity testing.
- Conformity and quality control - initial and subsequent type testing, factory production control (FPC), certification/evaluation of conformity.
- Installation, marking and documentation - installation instructions, packaging, designation and marking requirements.
Practical applications and users
EN ISO 10380 is a base standard for general‑purpose corrugated metal hoses used where flexibility, pressure containment and durability are required. Typical practical uses and beneficiaries:
- Manufacturers and fabricators - design, produce and test hoses and assemblies to meet minimum safety and performance standards.
- Design engineers and specifiers - select appropriate hose types, sizes and materials for piping systems.
- Procurement and quality managers - ensure supplier compliance via required test reports, FPC and certification.
- Installation and maintenance teams - follow installation instructions and marking for safe assembly and replacement.
- Testing laboratories and certifiers - perform type tests and conformity assessments.
Common application sectors include oil & gas, chemical processing, power generation, marine/shipbuilding, HVAC and industrial process systems where flexible metal connections are needed.
Related standards
EN ISO 10380 references and aligns with other standards for materials, welding/brazing, testing and documentation, for example:
- ISO material standards (e.g., ISO 6208, ISO 9328‑7)
- Welding and brazing qualifications (ISO 13585, ISO 15614‑1, EN 287‑1)
- Non‑destructive testing and inspection documents (EN 1779, EN 10204)
Using EN ISO 10380:2012 in specifications helps ensure consistent, tested and certifiable corrugated metal hoses and hose assemblies across industries.
