What ANSI/ISEA 107 and EN ISO 20471 Mean for Your Hi-Vis Clothing Order

If you've ever placed a bulk order for hi-vis clothing and found yourself staring at a product spec sheet trying to decode "Class 2, Type R" or "Class 2 EN ISO 20471," you're not alone. These standards are referenced constantly in the safety workwear industry, but they're rarely explained in plain language — and the differences between them matter enormously when you're sourcing for a specific market or industry.

This article is written for brand owners, distributors, and procurement managers who need to make informed purchasing decisions, not for compliance officers writing policy documents. Let's cut through the jargon.

Why Hi-Vis Standards Exist in the First Place

High-visibility clothing exists because people get struck by vehicles — on roads, in warehouses, at construction sites, near railway lines. The data is sobering. According to the U.S. Bureau of Labor Statistics, struck-by incidents from vehicles and mobile equipment account for a significant portion of workplace fatalities every year. Hi-vis standards exist to give garments a measurable, verifiable level of conspicuity — meaning they must be detectable at a defined distance under specific lighting conditions.

The two dominant standards you'll encounter are:

These two standards are not interchangeable. A garment certified under one does not automatically meet the other, though they share many underlying principles.

Breaking Down ANSI/ISEA 107

ANSI/ISEA 107 (latest version: 2020) classifies hi-vis garments by both Performance Class and Type. This two-axis system is what confuses most buyers.

Performance Classes (1, 2, 3)

The performance class relates to the amount of fluorescent background material and retroreflective tape on a garment. More hazardous environments require higher classes.

Types (O, R, P)

The Type designation tells you where the garment is intended to be used:

So when a spec sheet says "Class 2, Type R," it means a garment designed for roadway environments with a moderate level of visibility coverage. The majority of hi-vis vests and jackets sold to road and construction contractors in the US fall under this classification.

The E-Series Supplement

ANSI/ISEA 107-2020 introduced the "E-Series" for enhanced visibility products that include electronic elements like LED lighting. Most buyers don't need to worry about this yet, but it's worth knowing it exists.

Breaking Down EN ISO 20471

EN ISO 20471 (2013, amended 2016) is the European standard and uses a simpler Class 1, 2, 3 system without the Type designation. The minimum material requirements are defined in square metres of both fluorescent background material and retroreflective tape.

One key distinction with EN ISO 20471: it specifies both the *amount* and the *placement* of retroreflective material more precisely. The standard requires retroreflective bands to encircle the torso and limbs, ensuring visibility from all angles — not just front and back.

EN ISO 20471 also governs the photometric performance of the retroreflective material itself, specifying minimum retroreflection coefficients (measured in cd·lx⁻¹·m⁻²) at defined observation and entrance angles. This is why you can't simply slap cheap reflective tape on a vest and call it EN ISO 20471 compliant — the tape itself must meet minimum performance specifications.

Key Differences Between ANSI and EN ISO

| Feature | ANSI/ISEA 107 | EN ISO 20471 |

|---|---|---|

| Markets | US, Canada | EU, Middle East, Australia, global |

| Classification System | Class + Type | Class only |

| Material Minimums | Specified by class/type | Specified in m² |

| Retroreflective Placement | General guidance | Precise circumferential requirements |

| Third-Party Testing | Required for certification | Required for CE marking |

The practical implication for buyers: if you're sourcing for a US client, you need ANSI/ISEA 107. If you're selling into European or Middle Eastern markets, you need EN ISO 20471. If you need to serve both markets, your manufacturer needs to be capable of producing garments that meet both standards — which is possible but requires careful specification.

What to Ask Your Manufacturer

When placing a hi-vis clothing order, here are the questions that separate experienced buyers from those who end up with unusable inventory:

1. What test reports do you have? Legitimate compliance requires third-party testing. Ask for the actual test reports, not just a claim on the product label. Reputable manufacturers will have documentation from accredited labs.

2. What retroreflective tape do you use? The tape is the most critical component. 3M Scotchlite is the gold standard, but there are certified alternatives. Generic, uncertified tape is a red flag. We cover this in detail in our guide on reflective tape types and 3M Scotchlite.

3. What's the minimum background material area? For ANSI Class 2 Type R vests, the minimum fluorescent background material is 775 in² (5,000 cm²). Ask your supplier to confirm their garment meets this threshold.

4. Can you provide fabric specs? Most hi-vis garments use 100% polyester in fluorescent yellow-green, orange-red, or red. The fluorescent dye must maintain its photometric performance after multiple wash cycles — ask for wash fastness data.

5. Do you offer both ANSI and EN ISO options? If you serve multiple markets, a manufacturer who can produce to both standards will save you enormous logistics headaches.

Common Sourcing Mistakes

After years in the workwear supply chain, these are the mistakes that come up repeatedly:

Assuming a Class 2 garment is always Class 2. The class printed on the label only means something if it's backed by third-party testing. Plenty of cheap imports claim compliance without the paperwork to prove it. When a distributor's client gets audited on a jobsite, a garment with an unverifiable compliance claim is worthless — and the brand that sold it takes the reputational hit.

Not specifying the standard in the purchase order. "Hi-vis vest, fluorescent yellow" is not a specification. Your PO needs to state the standard (ANSI/ISEA 107-2020 or EN ISO 20471:2013), the class, and for ANSI, the type. Any reputable manufacturer will ask you for this — if they don't, that tells you something.

Ordering one-size construction. Hi-vis garments need to be worn *over* other clothing. A vest that fits a worker in a t-shirt will be too small over a winter jacket. Size your orders to account for seasonal layering.

Ignoring retroreflective tape width. EN ISO 20471 requires a minimum 50mm tape width for Class 2 and 3. ANSI is more flexible, but narrower tape provides less retroreflection area. Some cheaper manufacturers use 25mm tape and technically meet the letter of the standard while providing meaningfully less visibility.

Certification Markings

For EN ISO 20471 garments sold in Europe, you'll see a CE marking along with a four-digit notified body number. This indicates third-party assessment. For ANSI/ISEA 107, there's no government-mandated CE equivalent — but reputable manufacturers will still provide lab test reports from ANSI-accredited testing laboratories like SGS, Bureau Veritas, or Intertek.

Always ask for the test report. Not the certificate. The actual report, with test results, sample descriptions, and accreditation details.

Planning Your Order

Once you've got the standards sorted, work backwards from your end-user requirements:

1. Identify the regulatory environment — OSHA/MUTCD for US, CE marking for Europe

2. Determine the risk level — what class is required?

3. Specify garment type — vest, jacket, coverall, polo?

4. Confirm reflective tape spec — width, retroreflection coefficient, manufacturer

5. Specify background material — color (yellow-green vs orange-red), fabric weight, mesh vs solid

6. Define branding requirements — will you be adding logos via embroidery or printing?
