EN ISO 14116

EN ISO 14116 is a European and international standard for flame-limited protective clothing. It applies to garments designed to reduce the spread of flame when briefly exposed to fire, rather than providing full flame or heat protection.

The standard is typically used for workwear worn in environments where there is an occasional, low-level risk of flame contact — or as part of a layered PPE system alongside higher-level protective garments.

EN ISO 14116 focuses on flame spread only. It ensures that fabrics do not continue to burn, melt, or drip after brief exposure to flame, helping to reduce injury severity.

EN ISO 11612, by contrast, is designed for higher-risk environments and covers protection against heat and flame across multiple performance areas. In simple terms, EN ISO 14116 is suitable for lower-risk or layering applications, whilst EN ISO 11612 is required where direct heat or flame exposure is expected.

EN ISO 14116 garments are classified using an index system that reflects their level of flame-limited performance.

Index 1 offers the lowest level of protection and is often used where flame exposure is unlikely but possible. Index 2 and Index 3 provide increasing levels of flame resistance, with stricter performance requirements during testing.

Crucially, Index 1 garments must not be worn next to the skin unless combined with higher-index layers, as they may ignite during exposure.

EN ISO 14116 is suitable for workers in industries where there is a risk of brief, accidental contact with flame — but not sustained heat exposure.

This can include maintenance teams, engineers, transport and logistics workers, and industrial staff who require everyday workwear with added flame-limited properties, often as part of a layered PPE approach.

Yes — layering is one of the most common applications for EN ISO 14116 clothing.

EN ISO 14116-certified garments are frequently worn beneath or over other PPE, such as EN ISO 11612 flame-resistant outerwear or arc flash protection. When layered correctly, they help improve overall safety by ensuring each garment in the system contributes to flame protection rather than increasing risk.

It does. The standard can be applied to base layers, mid-layers, and outer garments, depending on the index level and intended use.

At alsico, we consider how garments will be worn in real working conditions — ensuring base layers, coveralls, jackets, or overshirts are specified correctly to support safe layering and compliance.

Choosing the correct index depends on your workplace risk assessment, including the likelihood of flame exposure and whether garments will be worn next to the skin.

Our team works closely with customers to understand their operational risks, existing PPE systems, and compliance requirements. This allows us to recommend the most appropriate index rating — without over- or under-specifying protection.

Yes. alsico supplies EN ISO 14116-certified garments at scale for national and multi-site operations.

With in-house expertise, robust supply chains, and long-standing experience supporting complex PPE contracts, we ensure consistency, compliance, and reliability across every order.

Absolutely. EN ISO 14116 garments can be customised with company branding, colours, and design features — provided all modifications maintain compliance with the standard.

At alsico, branding is carefully integrated to ensure it does not compromise flame performance, giving you workwear that is both compliant and clearly aligned with your brand.
