EN ISO 11611 welding apron
Updated: 18 October 2026
An amazon.co.uk title says flame resistant, the photographs show thick leather and the star average looks reassuring. None of that establishes an EN ISO 11611 welding apron. The exact garment needs a label and supporting documentation identifying the standard, performance class and flame-spread code. Class 2 is the higher spatter and radiant-heat class. A1 refers to surface ignition testing, while A2 refers to edge ignition. In our [welding apron comparison](/hub/soldering-and-welding/welding-apron), none of the twelve Amazon listing files states EN ISO 11611. One Portwest model has separate trade documentation, but that claim must remain separate from the unmarked Amazon row.

What EN ISO 11611 covers and what it does not
EN ISO 11611 is the protective-clothing standard for welding and allied processes. It addresses hazards including small splashes of molten metal, short contact with flame, radiant heat from the arc and optical radiation. Garments can include full clothing as well as partial protective items such as aprons, sleeves and gaiters. A leather apron can therefore carry a class, but it still covers only the area under the panel.
The standard does not turn an apron into complete PPE. Hands, face and feet fall outside its clothing coverage, and a front panel leaves arms and much of the legs and back exposed. Welding fume is an inhalation hazard requiring effective extraction and, where necessary, respiratory protective equipment. HSE guidance also expects suitable gloves, eye and face protection, and clothing covering arms and legs.
Nor should the electrical statement be overstated. ISO 11611:2015 includes limited protection against brief, accidental contact with live electrical conductors at voltages of approximately 100 V DC under specified conditions. It is not protection against electric shock in general. HSE warns that damp, dirty or otherwise conductive clothing increases risk, so keep the garment dry and do not rely on leather as electrical insulation.
The adopted UK reference is commonly shown as BS EN ISO 11611:2015. A newer ISO 11611:2024 edition exists, but that does not automatically make every correctly certified 2015-labelled garment invalid. Check the applicable declaration, purchasing specification and current UK requirements rather than crossing out an older date on sight.
Class 1, Class 2, A1 and A2
Class 1 is the lower of the two performance classes. Buyer-facing guidance associates it with less hazardous techniques and conditions, including gas welding, TIG, low-current MIG, microplasma work and MMA welding with rutile-covered electrodes. Typical environments provide relatively low levels of spatter and radiant heat. It may be appropriate for lighter bench work when the full risk assessment agrees.
Class 2 is the higher class, intended for techniques and situations producing more spatter or radiant heat. Examples commonly include MMA with basic or cellulose-covered electrodes, MAG, high-current MIG, self-shielded flux-cored welding, plasma or oxygen cutting, gouging, overhead work and confined spaces. The class is not a licence to ignore coverage: a Class 2 apron still leaves body areas outside the panel.
The letter-number code addresses limited flame spread. A1 indicates surface ignition testing and A2 indicates edge ignition testing under the related test method. Some garments carry A1, while others state A1+A2. Do not infer the missing code or assume that two products with similar-looking leather have the same result.
The Portwest UK declaration for the SW10 model identifies EN ISO 11611 Class 2 (A1) under the UK PPE framework. A separate Micronclean declaration for one leather apron also states Class 2 A1 and instructs users to wear it over a suit of at least Class 1. That instruction belongs to that product. Always follow the exact manufacturer's instructions supplied with your apron.
What an unmarked Amazon listing has not proved
Every product row in this comparison records class stated: not stated. Several titles use phrases such as flame resistant, heat resistant or Kevlar stitching, but those are not class markings. A heavy stated weight is not enough either: the AOUCHI says 1 kg and the LeaSeek cross-back bib says 998 g, yet neither Amazon file states EN ISO 11611. Weight helps compare likely substance, not tested performance.
The Portwest SW10TAR requires particular care. Its Amazon shelf price was £16.98 in the supplied file, which names the model but does not print the standard or class. Separate Portwest and UK trade sources describe the SW10 as Class 2 A1. That is relevant model-level evidence, but before buying for a class requirement you should confirm that the exact seller's item carries the correct label and comes with the matching declaration.
Review averages cannot fill this gap. Eight of the twelve files have one ASIN in the product URL and another in the product-details line, so their displayed review counts are flagged rather than clean. Even a perfectly matched 5.0 average would report customer satisfaction, not a notified or approved-body test. One listing, B0H2T53658, has no brand line and no customer reviews at all.
Use the leather welding apron buying guide for fit, weight and pocket trade-offs, but obtain technical documentation when the class matters. Look for a durable garment label, the manufacturer and model, the standard and class, care instructions and a declaration that identifies the same product. If those pieces do not line up, ask the supplier rather than reconstructing a claim from search results.
When you need the label
An employer selecting PPE must assess the risk and provide suitable equipment under the Personal Protective Equipment at Work Regulations 1992, with duties extended to limb (b) workers from 2022. That does not mean every welding task automatically demands the same class. It means the chosen clothing, its coverage and its demonstrated performance must be suitable for the actual process and conditions.
A hobbyist working privately is not in the same employment-duty position, but the hazard does not disappear. If you use high-current MIG, flux-cored wire, cutting or gouging, work overhead or enter a confined space, seek competent advice and do not rely on an unmarked marketplace title. The best welding apron UK picks do not crown a certification winner because the Amazon files do not supply the required class evidence.
Shape remains a separate decision. A certified bib and a certified split-leg garment can share a class while covering the body differently. Read our bib versus split-leg welding apron guide after defining the required class, then check that the chosen panel covers the spark path in your real posture.

Common questions
What is the difference between Class 1 and Class 2?
Class 1 covers lower levels of spatter and radiant heat associated with lighter welding conditions. Class 2 is the higher performance class for more hazardous techniques and environments. Match the class to a competent risk assessment. Do not choose Class 1 merely because the work is occasional.
What does A1 mean next to the class?
A1 identifies limited-flame-spread performance using surface ignition. A2 refers to edge ignition, and some garments show A1+A2. The code is separate from Class 1 or Class 2, so read the complete marking rather than treating any single number or letter as the whole result.
Is a 2015 label obsolete because a 2024 edition exists?
Not automatically. BS EN ISO 11611:2015 remains visible in UK product documentation, and the appearance of a later international edition does not by itself void genuine existing certification. Check the declaration, current purchasing requirement and applicable conformity route for the exact product.
Does flame resistant prove compliance?
No. It is not a substitute for the standard, class and supporting declaration. The same applies to heat resistant, leather thickness or Kevlar-stitch claims. These may be useful features, but they do not let you assign Class 1, Class 2, A1 or A2.
Does the Portwest SW10 on Amazon state Class 2?
The Amazon file used for this comparison does not state the class. A separate Portwest declaration for the SW10 model states Class 2 A1. Verify the label and declaration supplied by the exact seller before treating the purchased item as meeting a class requirement.
Can an apron be my only welding PPE?
No. It is partial body protection. You still need clothing for exposed arms and legs, suitable gloves, footwear, and eye and face protection, plus controls for fume. The exact system depends on the process, position, current, consumable and workplace conditions.
Who supplies suitable PPE at work?
Employers have duties under the PPE at Work Regulations to provide suitable PPE to employees, with the 2022 changes extending relevant duties to limb (b) workers. Selection must follow the risk assessment and include compatibility, fit, training, maintenance and replacement, not merely the purchase of a labelled apron.
