Overview
EN 1256:2006 is a European Standard issued by CEN that specifies performance and test requirements for hose assemblies used in gas welding, cutting, and allied processes. It applies specifically to hose assemblies supplied in assembled condition using rubber hoses compliant with EN 559. This standard ensures safety, reliability, and quality in hose assemblies for gas welding equipment, focusing on hose assembly construction, testing, and marking.
This standard supersedes EN 1256:1996 and guides manufacturers, suppliers, and users of hose assemblies in the welding and cutting industry across the European Union.
Key Topics
Scope and Applicability
EN 1256:2006 covers hose assemblies made from rubber hoses compliant with EN 559. It excludes hose assemblies using non-compliant hoses such as high-pressure hoses.Materials and Construction
Hose assemblies must use:- Hose connections per EN 560
- Rubber hoses per EN 559
- Corrosion-resistant materials for hose mounting devices (e.g., ferrules or hose clips) compliant with EN 29539
Greases or pastes are prohibited in assembly manufacture.
Design Requirements
- Hose tails must have smooth profiles without sharp edges to prevent damage during assembly or use.
- The mounting area must securely hold hose mounting devices (ferrules or hose clips), which must provide reproducible, non-detachable crimping.
- No worm screw or detachable clips are permitted for securing hoses.
- Kinking protection may be added to prevent hose damage near the coupling.
Performance Testing
Hose assemblies undergo rigorous testing to ensure:- Gas Tightness: Leakage not exceeding 4 cm³/hour at maximum operating pressure (tested as per EN 29090).
- Resistance to Separation Under Pressure: No hose separation from hose tails under hydrostatic pressure three times the maximum operating pressure.
- Resistance to Axial Load: The hose assembly withstands specific axial loads without separation or component failure. Post-test gas tightness must be maintained.
Marking Requirements
Hose assemblies must be durably marked with:- Manufacturer name or trademark
- Reference to EN 1256 standard
Markings can be on the hose mounting device or a separate band near the coupling.
Informative Annexes
- Annex A: Guidance on recommended hose tail dimensions for optimal hose assembly and manufacturing.
- Annex B: Examples of design for kinking protection to prevent hose damage in critical areas.
Applications
EN 1256:2006 is essential for industries and professionals involved in:
- Gas welding and cutting operations
- Manufacturing and assembly of gas welding equipment components
- Quality assurance and compliance testing of hose assemblies
- Safety management in industrial welding environments
- Design and supply of welding accessories, including hoses and connectors
By adopting EN 1256:2006, organizations ensure that hose assemblies meet European safety and performance standards, minimizing risks such as gas leaks, hose failures, and operational hazards.
Related Standards
For comprehensive compliance and compatibility, EN 1256 references and aligns with the following standards:
- EN 559: Rubber hoses for welding, cutting, and allied processes – essential for hose compliance.
- EN 560: Hose connections for equipment used in welding and cutting – defines coupling parts like hose tails.
- EN 29090: Testing of gas tightness for welding equipment – outlines leakage test procedures.
- EN 29539: Material requirements for gas welding and cutting equipment components – ensures chemical and mechanical suitability.
Summary
EN 1256:2006 provides clear specifications and testing protocols for hose assemblies used in gas welding and cutting, focusing on safety, durability, and interoperability. It ensures that hose assemblies made with EN 559 compliant rubber hoses and compatible connections are constructed and tested to withstand operational stresses without risk of leakage or failure.
This standard is vital for manufacturers, safety inspectors, engineers, and end-users aiming to meet European regulatory requirements and maintain high safety standards in gas welding equipment. Implementing EN 1256 ensures long-lasting, secure hose assemblies that support effective welding, cutting, and allied gas processes.
