EN 17353 and ANSI/ISEA 107 both deal with being seen, but they come from different markets and answer different questions. ANSI/ISEA 107 is the American high-visibility apparel standard used mainly for work. EN 17353 is the European standard for medium-risk enhanced visibility under the PPE Regulation. Exporters who sell to both markets often ask whether one certificate can cover both. The short answer is no.
Side-by-side comparison
| Point | EN 17353:2020+A1:2025 | ANSI/ISEA 107-2020 |
|---|---|---|
| Market | EU / EEA (and UK via UKCA) | United States |
| Risk focus | Medium risk: cyclists, pedestrians, low-speed environments | Occupational high visibility, from low-speed off-road work to highways |
| Classification | Types A, B1, B2, B3, AB2, AB3 by day/night use and material placement | Types O, R, P with Performance Classes 1, 2, 3 (plus Class E accessories) |
| Fluorescent colours | Seven, including yellow-green, orange and pink | Yellow-green, orange-red and red |
| Free-hanging and limb devices | Yes: Types B1 and B2 | No equivalent device classes |
| Children’s sizes | Separate lower area values for users up to 140 cm | No separate children’s area values |
| Conformity route | CE marking after EU type-examination by a notified body (Category II PPE) | Manufacturer’s declaration of compliance based on accredited third-party testing |
1. Different risk models
ANSI/ISEA 107 starts from the workplace. Type O covers off-road work such as warehouses and parking areas, Type R covers roadway and temporary traffic control, and Type P covers public safety such as police and emergency responders. Performance Classes 1 to 3 scale the amount of material with the hazard.
EN 17353 starts from the user’s visibility need. Is the risk in daylight, in darkness or both, and is it enough to recognise movement or does the user need to be recognised as a human form? High-risk workwear in Europe is a separate standard, EN ISO 20471, which is the closer counterpart to ANSI/ISEA 107.
2. Material areas
For orientation, the ANSI/ISEA 107 minimum background areas are roughly 0.14 m² for Class 1, 0.50 m² for Class 2 and 0.80 m² for Class 3, with retroreflective minimums of about 0.10, 0.13 and 0.20 m². EN 17353 asks for 0.24 m² of fluorescent material and 0.08 m² of retroreflective material for an adult AB3 garment, and lower values for children.
So an EN 17353 AB3 vest typically carries less retroreflective material than even an ANSI Class 1 garment. A product designed for EN 17353 rarely meets ANSI/ISEA 107 Class 2 without redesign.
3. Retroreflective performance
Both standards use similar photometric geometry, and both set 330 cd/(lx·m²) at 12′ observation and 5° entrance angle for new high-performance separate retroreflective material. The full angle tables, durability tests and post-wash requirements differ, so a tape test report for one standard does not automatically cover the other. Ask the supplier for reports against each standard you sell under.
4. Colours
EN 17353’s wider colour range, which adds yellow-green, yellow-orange, orange and pink boxes, is attractive for consumer and children’s products. Those colours do not satisfy ANSI/ISEA 107, which recognises fluorescent yellow-green, orange-red and red.
5. Certification and labelling
In Europe, EN 17353 products are Category II PPE. A notified body performs EU type-examination, the manufacturer issues an EU Declaration of Conformity and applies the CE mark. In the United States, ANSI/ISEA 107 compliance is declared by the manufacturer on the basis of testing by an accredited laboratory, and the label states the type and class.
Which standard should an exporter choose?
- Consumer products for Europe, such as cycling, running, children’s vests, reflectors and arm bands: EN 17353.
- Workwear for US job sites and roads: ANSI/ISEA 107, with the type and class required by the employer or highway authority.
- Workwear for high-risk European roadwork: EN ISO 20471.
- One design for both markets: possible only if the garment is designed to the stricter areas and colours, and tested separately against each standard.
FAQ
Can an ANSI Class 2 vest be sold in the EU as EN 17353?
Not without EU type-examination against EN 17353. The design may already meet the areas, but the certification, marking and user information must follow the EU route.
Is there a US equivalent of the B1 hanging reflector?
No. ANSI/ISEA 107 does not classify free-hanging reflectors or limb bands as stand-alone products.
Conclusion
EN 17353 vs ANSI/ISEA 107 is not a question of which is stricter, but of which market and which risk. Use EN 17353 for medium-risk European consumer visibility, ANSI/ISEA 107 for American occupational high visibility, and test separately when one product must serve both.
