prEN ISO 8207:2025 – Gas Welding Equipment Hose Assemblies Specification

Overview

The prEN ISO 8207:2025 standard, developed by CEN and aligned with ISO/DIS 8207:2025, specifies the performance and test requirements for hose assemblies used in gas welding, cutting, and allied processes. These assemblies utilize rubber hoses compliant with ISO 3821 and are intended for assembled hose conditions connected downstream of pressure regulators. The document provides essential guidelines on materials, construction, marking, and rigorous testing to ensure safety, reliability, and gas-tight integrity under operational stresses.

Key Topics

• Scope and Application
  This standard applies specifically to rubber hose assemblies with nominal sizes up to 20.0 mm, excluding high-pressure assemblies upstream of regulators. It is relevant for equipment used in gas welding, flame cutting, and related processes.

• Materials and Construction

  • Hose assemblies must be manufactured from hoses conforming to ISO 3821.
  • All components contacting the gas supply must meet ISO 9539 corrosion resistance requirements.
  • The hose tail must have a smooth, rounded profile to prevent damage during use and ensure secure hose mounting.
  • Hose fittings must be permanently secured by compatible mounting devices that prevent detachment under pressure or axial load - worm drive and detachable clamps are not permitted.

• Marking Requirements
  Durable markings are mandatory, including the manufacturer’s name or trademark and a reference to the ISO 8207 standard. Additional markings may include assembly date codes to help track production batches for quality assurance.

• Performance and Testing Criteria
  Ensuring safety and integrity through:

  • Gas Tightness Test: Conducted per ISO 9090, hose assemblies must meet strict leakage thresholds.
  • Resistance to Separation Under Pressure: Tested at three times the hose's maximum working pressure for at least one minute with no separation allowed.
  • Axial Load Resistance: The hose assembly must withstand specified axial loads (ranging from 450 N to 1700 N depending on nominal hose size) without component separation or gas tightness failure.

• Kinking Protection Design
  Annex A provides guidance on optional kinking protection features to prevent hose damage where it exits the hose tail, enhancing durability in demanding environments.

Applications

• Industrial Gas Welding and Cutting
  The standard ensures that hose assemblies used in welding and cutting operations are safe and reliable, minimizing risks of gas leakage and hose failure during critical tasks.

• Maintenance and Equipment Safety
  Companies can use ISO 8207-compliant hoses to maintain high standards of operational safety and meet regulatory requirements for gas welding equipment.

• Quality Control and Procurement
  Incorporating this standard into procurement specifications helps manufacturers, suppliers, and end-users verify the quality and performance of hose assemblies before deployment.

Related Standards

• ISO 3821 – Rubber hoses for welding, cutting, and allied processes
• ISO 9090 – Gas tightness testing procedures for welding equipment
• ISO 9539 – Material requirements for gas welding equipment components
• ISO 8330 – Vocabulary for rubber and plastics hoses and hose assemblies

By adhering to prEN ISO 8207:2025, stakeholders in the gas welding industry can ensure the reliability, safety, and regulatory compliance of hose assemblies essential for effective welding and cutting operations. This standard supports best practices in the design, manufacture, and testing of critical gas supply components.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
