EN ISO 11611
European standard for protective clothing used in welding and allied processes.
EN ISO 11611 sets the standard for protective clothing designed for welding and related tasks, guarding against heat, sparks, and molten metal splash. Alsico manufactures garments that meet and exceed EN ISO 11611 requirements, ensuring safety, comfort, and compliance for workers in fabrication, maintenance, and heavy industry.
what is EN ISO 11611?
EN ISO 11611 is an international safety standard specifying minimum performance requirements for protective clothing worn during welding and allied processes. The standard covers resistance to flame, heat transfer, and molten metal splash, helping protect workers from serious burns and injuries. Alsico’s garments are tested and certified to ISO 11611, ensuring reliable protection without compromising on comfort or functionality.
EN ISO 11611: protective standards for welding PPE
EN ISO 11611 sets the benchmark for protective clothing used in welding, metal cutting, grinding, and other high-heat processes. The standard ensures that workers are shielded from molten metal, radiant heat, and accidental contact with flames, helping safety managers maintain compliance and minimise workplace risk.

how alsico tests for EN ISO 11611 compliance
Every relevant alsico garment undergoes extensive testing to meet the requirements of EN ISO 11611. Our procedures assess resistance to ignition, molten metal splash, radiant heat, and seam strength, ensuring our protective clothing performs reliably in real-world welding and fabrication environments.
testing procedures
- Resistance to ignition – fabrics are tested to ensure they do not catch fire easily when exposed to sparks or flames.
- Molten metal splash – garments are evaluated for protection against molten droplets from welding, cutting, or grinding processes.
- Radiant heat – clothing is tested to withstand exposure to heat radiating from welding arcs or hot surfaces.
- Seam strength – reinforced seams are checked for durability to prevent garment failure under movement and strain.
additional quality checks
- Fabric integrity – ensures no compromise in flame-resistant finishes after repeated wear and laundering.
- Comfort and fit – garments are assessed to allow freedom of movement while maintaining protective coverage.
- Certification verification – each batch is checked against EN ISO 11611 standards before being released to customers.
This rigorous approach guarantees that alsico’s EN ISO 11611 clothing not only meets international safety standards but also provides peace of mind for procurement and safety managers alike.

frequently asked questions
EN ISO 11611 is an European and international standard for protective clothing used in welding, cutting, and similar high-heat processes. It ensures garments provide reliable protection against molten metal, sparks, radiant heat, and accidental flame contact.
While EN ISO 11611 focuses on protection for welding and allied processes, EN ISO 11612 is designed for general heat and flame-resistant clothing used in industries such as petrochemical, metalwork, and foundries. EN ISO 11612 garments protect against radiant, convective, and contact heat, whereas EN ISO 11611 is specifically tailored to welding hazards.
Any worker exposed to welding, cutting, grinding, or similar processes requires EN ISO 11611-certified clothing. This includes welders, fabricators, metalworkers, and technicians operating in environments with sparks, molten metal, or high heat exposure.
- Class 1 – suitable for less hazardous welding tasks, offering protection against lower levels of spatter and radiant heat.
- Class 2 – intended for higher-risk welding techniques, providing enhanced protection against intense spatter, radiant heat, and flame exposure.
Garments are tested for resistance to ignition, molten metal splash, radiant heat, seam strength, fabric integrity, and overall durability. This ensures they perform reliably in real-world welding and fabrication conditions while complying with international standards.
