EN ISO 20471 certified high-visibility vests are critical personal protective equipment that make workers visible in hazardous environments. İlke Textiles manufactures Class 1, 2, and 3 hi-vis vests with retroreflective tape that maintains performance through 50+ industrial wash cycles. CE marked and ready for export.
EN ISO 20471 defines three performance classes based on the minimum area of visible materials.
Minimum 0.14 m² fluorescent material + 0.10 m² retroreflective tape. Suitable for low-traffic environments, parking areas, and supervised work zones.
Minimum 0.50 m² fluorescent material + 0.13 m² retroreflective tape. The most common class for construction sites, warehouses, logistics, and roadside operations.
Minimum 0.80 m² fluorescent material + 0.20 m² retroreflective tape. Required for high-speed traffic zones, highway construction, airport aprons, and complex hazard areas.
EN ISO 20471:2013 (High-visibility clothing — Test methods and requirements) is the internationally recognized standard that defines how high-visibility warning garments must perform to protect workers in environments where they risk being struck by vehicles or mobile machinery. This standard replaced the earlier EN 471:2003+A1:2007 and is harmonized across the European Union as part of PPE Regulation (EU) 2016/425. For procurement managers sourcing hi-vis vests for their organizations, understanding this standard is essential to ensuring legal compliance and genuine worker protection.
The fluorescent background material is what makes workers visible during daylight hours. EN ISO 20471 specifies that this material must fall within defined chromaticity coordinates — essentially restricting the allowable colors to fluorescent yellow, fluorescent orange-red, and fluorescent red. These specific hues are scientifically chosen because they contrast most strongly against typical workplace backgrounds (grey concrete, dark asphalt, green vegetation, brown earth) under daylight conditions.
İlke Textiles sources fluorescent fabrics from certified European and Turkish mills that undergo regular color consistency testing. Each fabric batch is verified against the standard's chromaticity requirements before entering production. This batch-level control ensures that every vest we ship meets the precise color specification — not just the first production run, but every subsequent repeat order as well.
Retroreflective tape is the component that makes workers visible at night when illuminated by vehicle headlights or machinery lighting. EN ISO 20471 specifies minimum coefficients of retroreflection (measured in cd/lx/m²) at specific entrance and observation angles. The tape must perform effectively when light strikes it from various directions — not just head-on — because real-world visibility scenarios involve vehicles approaching from different angles.
Our factory uses retroreflective tape from leading manufacturers including 3M Scotchlite and equivalent certified suppliers. We apply tape using both heat-seal bonding and industrial stitching methods, depending on the garment design and end-use requirements. Heat-sealed tape provides a cleaner appearance and excellent wash durability, while sewn tape offers additional mechanical security for heavy-duty applications. All tape application follows the standard's placement rules: horizontal bands around the torso, with specific minimum widths (50mm recommended) and spacing requirements to ensure the wearer is recognizable as a person from all angles.
One of the most critical aspects of EN ISO 20471 is the requirement that garments maintain their performance properties through a defined number of wash cycles. The standard requires testing after a minimum number of cleaning cycles (typically 25 for basic and 50 for professional use) to verify that both the fluorescent color and retroreflective performance remain within specification. İlke Textiles tests all certified products to 50 wash cycles at 60°C in accordance with ISO 6330, verifying both color fastness and retroreflective coefficient retention. This testing is conducted by accredited third-party laboratories, and test reports are available upon request.
Hi-vis vests sold within the EU must carry CE marking and be accompanied by a Declaration of Conformity (DoC) issued by the manufacturer. As a CE-marked manufacturer, İlke Textiles provides complete documentation packages for every hi-vis product including the EU Declaration of Conformity referencing EN ISO 20471:2013, type examination certificates from notified bodies, technical file documentation, user information and care labeling in the required languages, and test reports from accredited laboratories. This documentation package ensures that our customers face no compliance issues when importing hi-vis vests into EU, Balkan, or other markets that recognize CE marking.
Selecting the correct hi-vis class depends on your specific operational environment. For road construction and highway maintenance, Class 3 garments are typically mandated by national regulations. For warehouse and logistics operations, Class 2 provides the right balance of visibility and wearability. For visitor identification in controlled environments, Class 1 often meets the minimum requirement.

Learn More →EN ISO 20471:2013 is the European standard for high-visibility warning clothing. It specifies requirements for the color, retroreflective performance, minimum areas of visible materials, and placement of these materials on garments. Compliance ensures that workers are visible in all lighting conditions, significantly reducing accident risk in traffic, construction, and industrial environments.
The classes differ in the minimum area of fluorescent background material and retroreflective tape. Class 1 requires 0.14 m² background and 0.10 m² retroreflective — suitable for low-risk environments. Class 2 requires 0.50 m² background and 0.13 m² tape — the standard for most industrial applications. Class 3 requires 0.80 m² background and 0.20 m² tape — mandated for high-speed traffic zones and complex hazards.
Our EN ISO 20471 certified vests maintain their retroreflective performance and fluorescent color intensity through a minimum of 50 industrial wash cycles at 60°C, as verified through laboratory testing per the standard's requirements. We recommend avoiding bleach and fabric softeners to maximize garment lifespan.
EN ISO 20471 specifies three permitted fluorescent background colors: fluorescent yellow (the most common), fluorescent orange-red, and fluorescent red. These specific colors meet the standard's chromaticity requirements for maximum visibility. Contrast trim colors (navy, black, grey) can be added to non-critical zones.
While technically possible, we strongly recommend ordering vests with tape integrated during manufacturing. Factory-applied tape is positioned to meet EN ISO 20471 placement and area requirements, with bonding methods that ensure durability through industrial washing. Retrofitted tape often fails to meet the standard's specifications.
