Understanding ANSI/ISEA 107 and EN ISO 20471: A Buyer’s Guide to Hi-Vis Standards

When it comes to high-visibility clothing, color and brightness aren’t enough—you also need compliance.

But with multiple standards in play—ANSI/ISEA 107 (North America) and EN ISO 20471 (Europe)—many buyers get confused.
What do the classes mean? Can one garment meet both? What if you’re buying for export?

Let’s decode both standards and help you choose the right certified gear—for the right job, and the right geography.

Why Standards Matter in Hi-Vis Clothing

High-visibility PPE is only effective if it:

• Meets minimum surface area of fluorescent and reflective material
• Uses certified color + tape brightness
• Has visible placement zones (360° visibility, torso + limbs)
• Follows design rules like placement, fit, and durability
• Passes performance testing under defined lab conditions

⚠️ A hi-vis vest from the market without a certified label might look safe but fail at night or in fog.

✅ Standards ensure your garments work in real-world danger—not just look good in photos.

What Is ANSI/ISEA 107?

🇺🇸 ANSI/ISEA 107

Standard used in the United States and Canada for high-visibility apparel.

Originally issued by the American National Standards Institute (ANSI) and managed by ISEA.

Key elements:

• 3 Performance Classes (Class 1, 2, 3)
• Type O, R, and P (based on work environment)
• Requirements for background fabric area + reflective tape area
• Focus on day/night visibility + mobility

ANSI Classes at a Glance

✅ Class 3 must have sleeves + full torso reflectivity.

What Is EN ISO 20471?

🇪🇺 EN ISO 20471

Applies across Europe and most global export markets.

Managed by ISO and CEN, it harmonizes high-visibility standards in line with the European PPE Regulation (EU) 2016/425.

Key elements:

• Defines three classes (1–3) based on visible surface area
• Specific brightness levels (cd/lux/m²) for fluorescent + retroreflective materials
• Strict design, placement, labeling, and wash durability rules
• Allows colors: yellow, orange-red, red

EN ISO 20471 Classes at a Glance

✅ Class 3 = full-body visibility from all angles.

ANSI vs EN ISO: Key Differences

✅ If you’re selling to both markets, you may need garments with dual labeling (ANSI + EN certified).

Label Reading: What to Look For

A compliant hi-vis garment should have a clear internal label that shows:

• Certification logo (ANSI 107 or EN ISO 20471)
• Class level (1/2/3)
• Color code
• Manufacturer and batch
• Washing instructions
• Minimum performance lifespan (e.g. 25 washes)

⚠️ No label = no compliance = potential audit failure or safety violation.

Export Tip: Match Your Market

✅ Always check the project spec sheet or tender document—some even require dual certification.

What to Ask Before Buying Hi-Vis Workwear

• Is this garment certified or just “compliant-looking”?
• Do you have the certificate or lab test report?
• What’s the wash durability of the reflective material?
• Does it meet both ANSI and EN standards for international projects?
• Can I get Class 2 for vests, Class 3 for jackets in the same range?

At workwearsolutions, we supply high-visibility PPE with full certification, dual-standard options, and compliance-ready documentation.

Conclusion

Hi-vis clothing is one of the most regulated forms of workwear—and for good reason.

When choosing gear:

• Match to job site risk level (Class 1, 2, or 3)
• Match to region or project (ANSI or EN)
• Check the label and certificate, not just the look
• Know when dual compliance is required

Need help interpreting a project spec, or sourcing fully certified hi-vis gear for North America, Europe, or export markets? I’ll help you get it right—from compliance to comfort.
