EN ISO 20471 (Europe) certifies garments on photometric performance and minimum material areas across Classes 1–3, while ANSI/ISEA 107 (US) defines garment Types (O, R, P) and Performance Classes with prescribed tape geometry. Class numbers look similar but do not map directly — a US Class 2 is not an EU Class 2. Multi-market programs need separate certification per standard.
If you're sourcing hi-vis workwear for both European and North American operations, you've likely run into this problem: the same garment can't be certified to both EN ISO 20471 and ANSI/ISEA 107. They're not just different labels — they're fundamentally different standards, with different testing methods, different design rules, and different legal force.
The Core Difference: Photometric Performance vs Design Geometry
EN ISO 20471 (Europe) is primarily a photometric standard. It measures how much light the fluorescent material and retroreflective tape return to the source — the actual brightness. The design requirements (where the tape goes, how much background material) are secondary to the performance numbers.
ANSI/ISEA 107 (US/Canada) is primarily a design standard. It specifies exactly where reflective tape must be placed, how wide it must be, and what configuration it must form — with less emphasis on the raw photometric values.
This means:
- A garment can pass EN ISO 20471 with minimal tape if the tape is extremely bright
- A garment can fail ANSI/ISEA 107 even with very bright tape if the tape is in the wrong position or wrong width
Key Design Differences at a Glance
| Feature | EN ISO 20471 | ANSI/ISEA 107 |
- EN Class 3 ≈ ANSI Type R Class 3 (roughly equivalent)
- But the design requirements differ, so a garment certified to EN Class 3 may not meet ANSI Type R Class 3 tape configuration rules
Practical Sourcing Advice
If you need both certifications:
1. Design to ANSI first. ANSI's prescriptive tape placement is harder to satisfy than EN's performance-based approach. Meet ANSI's geometry, then verify the materials meet EN's photometric minimums.
2. Specify combined-performance tape. Some tape manufacturers offer products tested to both standards — the tape itself carries dual certification.
3. Test the finished garment, not just the materials. Both standards require garment-level testing. Material certificates alone don't certify the finished product.
4. Document everything. For EN, you need a Declaration of Conformity and CE marking. For ANSI, you need test reports from an accredited lab. Both require ongoing production quality control.
What This Means for Your Supply Chain
At Fujian Rising Outdoor Products, we manufacture hi-vis apparel to both standards — often for the same client operating in multiple markets. The key is starting with the right design blocks:
- Our EU production line uses patterns optimized for EN ISO 20471's performance approach
- Our US/Canada production line uses ANSI/ISEA 107's prescriptive tape geometry
- For clients needing both, we run parallel certification programs with SGS and Intertek
The result: garments that pass both standards, with full documentation for both regulatory frameworks.

| -------- | -------------- | --------------- |
| Background material | Minimum 0.5 m² (Class 3) | Minimum 0.31 m² (Class 3) |
| Reflective tape width | Minimum 50 mm | Minimum 50 mm (2") |
| Tape configuration | Two horizontal bands around torso, or one band + braces | Specific "H" or "X" patterns on back |
| Sleeve coverage | Encouraged but not mandatory | Class 3 requires sleeves with tape |
| Fluorescent colors | Yellow, orange-red, red | Yellow-green, orange-red |
The Class Systems Don't Map Directly
EN ISO 20471 uses Class 1, 2, 3 — with Class 3 being the highest visibility.
ANSI/ISEA 107 uses Type R (Roadway), Type P (Public Safety), Type O (Off-road) — each with Class 1, 2, 3.
The critical mistake buyers make: assuming EN Class 2 = ANSI Class 2. It doesn't.
- EN Class 2 ≈ ANSI Type R Class 2 (roughly equivalent for roadway work)
Frequently Asked Questions
Is ANSI Class 2 the same as EN ISO 20471 Class 2?+
No. The class systems do not map directly: minimum background and retroreflective areas differ, tape placement rules differ, and ANSI adds garment Types (O off-road, R roadway, P public safety) that EN does not use. Always state which standard and which class — never just Class 2.
Which standard should I specify for a European customer?+
EN ISO 20471 — it is the harmonized standard under the EU PPE Regulation, and CE-marked hi-vis for professional use is tested against it. Specify the class from the risk assessment: Class 1 low risk, Class 2 most general industry, Class 3 high-risk and high-speed traffic environments.
Can one garment meet both EN ISO 20471 and ANSI/ISEA 107?+
Yes, if designed to the stricter requirement of each: the higher minimum background area, tape geometry satisfying both layouts, and colours accepted by both (fluorescent yellow and orange-red work for both). It still needs two test programs and two sets of documentation.
What should I check on a factory’s EN ISO 20471 certificate?+
Which edition of the standard the certificate references, whether test reports come from an accredited lab, the certified class and wash-cycle count, and whether the certificate covers the garment as produced — including its logo placements and colour variant — not just a prototype.
