Overview
EN ISO 5172:2006/A2:2015 is a European amendment to the international standard ISO 5172:2006, focused on gas welding equipment, specifically blowpipes used for gas welding, heating, and cutting. Prepared by ISO/TC 44 in collaboration with CEN/TC 121, this amendment updates specifications and testing methods to align with recent developments in gas marking protocols. Adopted by CEN members across multiple European countries, this standard serves as a critical reference for ensuring the safety, quality, and interoperability of blowpipe equipment in gas welding processes.
Key Topics
- Blowpipe Specifications: Defines dimensional and performance requirements for blowpipes used in gas welding, heating, and cutting operations.
- Testing Procedures: Details mandatory tests to verify equipment durability, performance, and safety, ensuring conformity to high-quality standards.
- Gas Marking System: Updates marking protocols in line with the gas letter codes specified in ISO 10225, providing clear identification for fuel gases and oxygen.
- Modification Highlights:
- Replacement of table references for clarity.
- Incorporation of ISO 10225 for consistent gas equipment marking.
- Revised marking clause mandating the use of gas letter codes when chemical names/symbols cannot be displayed.
- Updated marking system table for improved clarity.
Applications
EN ISO 5172:2006/A2:2015 applies to manufacturers, suppliers, and users of gas welding equipment including:
- Industrial Fabrication: Ensuring blowpipes meet standardized safety and performance levels for cutting, welding, and heating metals.
- Maintenance and Repair: Supporting maintenance operations with standardized equipment specifications for replacement and testing.
- Safety Compliance: Helping regulatory bodies verify equipment marking and performance in workplaces handling flammable gases.
- Quality Assurance: Facilitating conformity assessment by providing clear test criteria and marking standards to reduce operational risks.
