ISO 8207:2026 - Gas welding equipment — Specification for hose assemblies for equipment for welding, cutting and allied processes
ISO 8207:2026 - Matériel de soudage au gaz — Spécifications relatives aux flexibles pour matériel de soudage, coupage et techniques connexes
Overview
ISO 8207: Gas welding equipment - Specification for hose assemblies for equipment for welding, cutting, and allied processes is an international standard developed by ISO/TC 44/SC 8. This standard defines the requirements for hose assemblies using rubber hoses for gas welding, cutting, and related processes. It specifies performance criteria and test methods to ensure safe, reliable connections throughout industrial gas distribution systems, excluding use upstream of the pressure regulators.
The latest edition updates definitions, revises construction requirements, and adds new hose sizes and axial load criteria, ensuring the standard remains aligned with industry needs and related ISO standards such as ISO 3821 and ISO 8330.
Key Topics
Scope and Applicability
- Applies to hose assemblies fabricated from rubber hoses up to nominal size 20.0, for use in gas welding, cutting, and similar allied processes.
- Not applicable to hose assemblies on the supply side (upstream) of gas pressure regulators.
Construction Requirements
- Hose assemblies must use rubber hoses compliant with ISO 3821.
- All fittings and clamping devices must be corrosion-resistant or protected appropriately.
- Hose tail and clamping device designs should prevent hose damage and ensure secure attachment.
Marking and Identification
- Assemblies must be clearly and durably marked with manufacturer details and reference to ISO 8207, typically on the end fitting or a band next to it.
- Optional marking may include date of assembly.
Performance and Testing
- Requirements include gas tightness, resistance to separation under pressure, and resistance under axial load.
- Sample assemblies are subjected to hydrostatic pressure, leak checks, and axial tension tests in accordance with referenced test methods (such as ISO 9090).
Kink Protection
- The standard provides design examples for optional kink protection to prevent hose failure at connection points, enhancing both safety and durability.
Applications
ISO 8207 serves as a key reference for manufacturers, suppliers, and users of gas welding equipment. Its requirements are essential across industries such as:
- Welding and Metal Fabrication
- Ensuring hose assemblies are robust and safe for delivering gases (e.g. oxygen, acetylene) under various pressures in critical metal working operations.
- Industrial Gas Distribution
- Providing confidence in equipment safety, particularly in oxy-fuel welding, cutting, and allied processes that require reliable gas transfer.
- Equipment Manufacturing
- Standardizing hose and fitting construction and testing simplifies compliance and enhances international trade for equipment manufacturers.
- Maintenance and Safety Compliance
- Facilities managers and safety inspectors rely on conformance to ISO 8207 to minimize risks of leaks or hose failures during operation.
Related Standards
To meet the requirements of ISO 8207 and related gas welding safety protocols, the following standards are often referenced:
- ISO 3821 – Gas welding equipment - 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 – Gas welding equipment - Hose connections for equipment for welding, cutting and allied processes
By adhering to ISO 8207, companies and professionals enhance safety, durability, and compliance in gas welding operations, supporting reliability and globalization of welding equipment markets.
