EN ISO 11611: Protective Clothing for Welding & Allied Processes

Understand classes, coverage and how to choose the right welder’s PPE for your team.

What is EN ISO 11611?

EN ISO 11611 defines the safety requirements for garments worn during welding and related hot work (cutting, gouging, grinding and similar). It ensures the clothing helps protect against small splashes of molten metal (spatter), brief contact with flame, and radiant heat from the welding arc. The standard also requires clothing construction that reduces snag and burn risk in welding conditions.

It covers garments like coveralls, jackets, trousers, and certain accessories (e.g., hoods, aprons, sleeves, gaiters) designed to protect the body in welding work. Protection for hands, face, eyes and most footwear is covered by other PPE standards and must be selected separately.

Who is it for?

Typical users include professionals engaged in:

  • MMA/MIG/MAG/TIG welding in fabrication, shipyards and heavy industry
  • Plasma and oxy‑fuel cutting, gouging and thermal spraying
  • Workshop & field repairs involving sparks, hot slag and radiant heat

For electric arc flash hazards in electrical work, use garments certified to IEC 61482‑2 (arc protection). For broader heat/flame risks beyond welding, consider EN ISO 11612.

How to read an EN ISO 11611 label

Labels typically show the standard, the class (1 or 2) and the flame‑spread test(s) achieved:
EN ISO 11611 Class 2 A1/A2

  • Class 1 – For less hazardous techniques and conditions (lower spatter, lower radiant heat)
  • Class 2 – For more hazardous techniques and conditions (higher spatter, higher radiant heat)
  • A1/A2 – Limited flame spread (A1 = surface ignition; A2 = edge ignition). Many garments achieve both.

Always check the garment’s pictogram and full CE label for the exact class and any additional certifications (e.g., high‑vis, anti‑static, rain or arc standards).

Performance classes at a glance

Class Typical processes Hazard profile
Class 1 Gas welding, TIG, low‑current MIG, micro‑plasma, brazing, spot welding; machine operations with limited spatter Lower levels of spatter and radiant heat; general bench or positional work
Class 2 MMA with basic/cellulose electrodes, MAG/MIG with higher current, self‑shielded flux‑cored, plasma/oxy‑fuel cutting, gouging, thermal spraying Higher spatter/radiant heat; overhead, confined, or difficult positions

Choose Class 2 where there is frequent heavy spatter, high heat load, or awkward positions that increase exposure.

Minimum construction & design expectations

  • Flame‑spread performance: Garments must achieve A1 and/or A2 limited flame spread.
  • Coverage & closures: Design avoids catch points and limits entry/retention of spatter—e.g., covered front closures, protected pockets, no exposed metal contacting the skin.
  • Durability: Materials and seams are evaluated for strength and heat exposure relevant to welding tasks.
  • Layering: Multi‑layer or accessory items (aprons, sleeves, hoods, gaiters) can be used to boost protection where exposure is highest.

How to choose the right EN ISO 11611 garment

  1. Map your processes: Identify welding processes, current, positions (overhead/confined) and duration of exposure.
  2. Pick the class: Use Class 1 for lighter techniques; upgrade to Class 2 for heavy spatter/high radiant heat tasks.
  3. Check A1/A2: Prefer garments that achieve both A1 and A2 flame‑spread tests where possible.
  4. Combine standards: If you also need high‑visibility, rain or arc protection, select multi‑norm garments with the required additional certifications.
  5. Fit & mobility: Ensure correct sizing for overlap and movement, especially for crouching or overhead work.

Care, laundering & lifetime

  • Follow the care label. Incorrect washing can degrade flame resistance, coatings and seam integrity.
  • Keep clean & repair promptly. Oil, slag and metal dust can affect performance and increase ignition risk; repair or replace if damaged.
  • Use compatible layers. Only add FR base/mid‑layers approved by the manufacturer for use under EN ISO 11611 garments.

Limitations & related standards

  • Arc flash: EN ISO 11611 is not an electric arc standard. For arc hazards, select garments certified to IEC 61482‑2.
  • Additional PPE needed: Gloves, boots, face and eye protection must be selected separately for welding tasks.

Typical selections by welding task

  • TIG / precision bench work: Class 1, A1/A2 jacket & trousers; add FR sleeves or apron for occasional higher exposure.
  • MIG/MAG structural welding: Class 2, A1/A2 coverall or jacket & trousers; add hood/apron/gaiters for heavy spatter zones.
  • Overhead / confined: Class 2, A1/A2 with extended coverage and accessories; ensure secure closures and minimal snag points.

FAQ

Is Class 2 always better than Class 1?
Class 2 offers higher protection for heavier techniques and positions with greater spatter/radiant heat, but may be heavier/warmer. Choose the class that matches your actual process risks.
Do EN ISO 11611 garments protect from electric shock?
They help minimize the possibility of shock from brief, accidental contact with low‑voltage live conductors during normal welding conditions, but they are not electrical PPE. Use appropriate electrical safety controls and arc‑rated PPE when required.
Should I add an apron or sleeves?
Yes—accessories like aprons, sleeves, hoods and gaiters can reinforce protection at high‑exposure areas (front torso, forearms, head/neck, lower legs/feet), especially in Class 2 tasks.
