Overview
EN ISO 14113:2013 (ISO 14113:2013) specifies requirements for rubber and plastics hoses and hose assemblies used with industrial gases up to 450 bar (45 MPa) within an ambient temperature range of −20 °C to +60 °C. The standard applies to hose assemblies that connect gas cylinders to manifolds or bundles before any pressure reduction stage. It excludes hoses for welding/cutting processes (see ISO 3821 and ISO 12170), refrigerated liquefied gases and LPG.
Key topics and technical requirements
The standard defines construction, testing and documentation requirements for high-pressure industrial gas hoses and assemblies. Major topics include:
- Scope and application: Use with compressed, liquefied and dissolved gases up to 450 bar; connection between cylinders and manifolds prior to pressure reduction.
- Materials and construction: Requirements for hose lining, cover, reinforcement and end fittings suitable for industrial gases.
- Dimensions and tolerances: Bore sizes, concentricity, cut lengths and assembly lengths following established hose sizing methods.
- Type tests (performance):
- Pressure resistance and hydrostatic testing.
- Adhesion testing for rubber hoses.
- Flexibility and low-temperature flexibility tests.
- Ozone and UV resistance for protective covers.
- Permeability to gas and electrical conductivity assessments.
- End fitting integrity and leak testing.
- Production tests: Routine pressure and leak tests for assembled hoses; cleaning and preparation requirements for oxygen service.
- Special normative annexes: Acetylene decomposition testing for high-pressure acetylene, oxygen pressure surge tests, and installation considerations for oxygen systems.
- Marking, packaging and instructions: Mandatory marking of hoses/assemblies and user instructions for safe installation and use.
Practical applications and users
EN ISO 14113:2013 is intended for organizations involved in the manufacture, testing, specification and use of high-pressure gas hose systems, including:
- Hose and fitting manufacturers
- Test laboratories and quality assurance teams
- Gas suppliers and cylinder/manifold system designers
- Safety and plant engineers specifying gas distribution components
- Procurement teams and regulatory bodies assessing compliance
Using this standard helps ensure hose assemblies are safe, compatible with gas types (including oxygen and acetylene when specified), and meet defined performance and documentation expectations.
