Overview

ISO 8207:2026 is an International Standard for gas welding equipment that specifies the performance and test requirements for hose assemblies supplied in assembled condition. It applies to hose assemblies using rubber hose according to ISO 3821 up to and including nominal size 20,0 for welding, cutting, and allied processes.

This standard is especially relevant for manufacturers, suppliers, and users who need clear requirements for gas hose assembly safety, gas tightness, and resistance to separation. It helps support consistent quality in gas welding systems and promotes dependable hose assembly design for industrial applications.

The document does not apply to high-pressure hose assemblies upstream of pressure regulators.

Key Topics

ISO 8207:2026 focuses on practical requirements that support safe and reliable hose assembly performance:

  • Construction requirements

    • Hose assemblies shall use hoses conforming to ISO 3821
    • Components in direct contact with gas supply shall conform to ISO 9539
    • Hose clamping device materials shall be corrosion resistant or protected against corrosion
    • No greases or pastes shall be used in manufacturing
  • Design considerations

    • Hose tail profiles shall avoid sharp edges that could damage the hose
    • Hose fittings shall provide secure mounting for the hose clamping device
    • Worm drive screw clips or similar detachable clamps shall not be used to secure the hose to the hose tail
    • Annex A gives examples of kinking protection design
  • Marking requirements

    • Durable marking shall include the manufacturer name or trade mark
    • Marking shall also reference ISO 8207
    • Optional date coding may be added for traceability
  • Performance and test methods

    • Gas tightness is verified in accordance with ISO 9090
    • Resistance to separation under pressure
    • Resistance to separation under axial load
    • Type testing is used to confirm compliance

Applications

ISO 8207:2026 supports a wide range of gas welding and cutting equipment applications where hose assemblies must remain secure and leak-resistant. Typical uses include:

  • Gas welding operations
  • Gas cutting equipment
  • Allied thermal processes
  • Hose assembly production and quality control
  • Product conformity assessment and supplier verification

For industry stakeholders, the standard provides a practical basis for evaluating hose assembly reliability, improving product consistency, and supporting safer equipment selection in welding environments.

Related Standards

ISO 8207:2026 is closely connected with other standards in the gas welding equipment family:

  • ISO 3821 - Rubber hoses for welding, cutting and allied processes
  • ISO 8330 - Rubber and plastics hoses and hose assemblies - Vocabulary
  • ISO 9090 - Gas tightness of equipment for gas welding and allied processes
  • ISO 9539 - Materials for equipment used in gas welding, cutting and allied processes
  • ISO 15296 - Gas welding equipment - Vocabulary
  • ISO/TR 28821 - Hose connections for equipment for welding, cutting and allied processes

Together, these standards support a structured approach to welding hose assembly specification, test methods, and equipment safety within the ISO welding standards framework.
