ANSI/ISEA 107: Types, Classes and What US Buyers Must Check

ANSI/ISEA 107 is the American national standard for high-visibility safety apparel. It answers two separate questions, and buyers routinely conflate them: who is the wearer exposed to (the Type), and how much visible material does the garment provide (the Class).

A garment can be the highest class available and still be the wrong Type for the job. A supplier can sell you the brightest tape on the market and still leave your garment non-compliant, because the standard regulates the finished garment's visible area and performance after care — not the roll of trim.

This guide is for US-facing workwear brands, distributors and uniform programmes specifying retroreflective trim. It explains the structure of the standard, how the Type and Class decisions differ, and what evidence to request. It is not a substitute for the standard text or your risk assessment.

What Does ANSI/ISEA 107 Cover?

The standard specifies requirements for high-visibility apparel intended to make the wearer visually conspicuous in hazardous situations, typically where vehicles or mobile equipment operate.

It covers:

• the performance of the fluorescent background material;
• the performance of the retroreflective material;
• the minimum area and configuration of both on the garment;
• performance after care, including laundering as claimed on the label;
• product marking and instructions.

It does not cover protective properties such as flame resistance, arc ratings or chemical resistance, each of which lives in its own standard. Nor does it cover traffic-sign sheeting, which is evaluated as sign material under a different framework; a sign film is not apparel trim.

What Is the Difference Between Type and Class?

These are two independent axes.

Type describes the work environment and therefore what the wearer must be visible against:

• Type O — off-road. For workers not exposed to public traffic or equipment moving at speed: warehouse, yard, parking, utility work away from the roadway.
• Type R — roadway. For workers exposed to public traffic and to construction equipment on or near the road.
• Type P — public safety. For police, fire, emergency medical and other responders whose duties involve exposure to traffic, often with additional requirements reflecting the tasks and equipment of those roles.

Class describes how much visible material the garment provides, in increasing order from Class 1 to Class 3. The class is determined by the minimum area of background and retroreflective material, and by how that material is arranged — whether it forms recognizable bands around the torso, arms and legs.

Class does not measure quality. A Class 3 garment built from ordinary trim is still Class 3 by area. A Class 1 garment built from the best trim available is still Class 1.

What Is Supplemental Class E?

Class E is a supplementary classification for lower-body garments — trousers, shorts, gaiters — that do not qualify as a standalone performance class but add visible area when worn with a compliant Class 2 or Class 3 upper garment.

The practical consequence: a Class E trouser does not make a wearer compliant on its own. It contributes area to an outfit that already meets a class through its upper garment. Confirm the combination rule rather than treating Class E as a class in its own right.

Why the Area Rules Matter More Than the Tape

The standard sets minimum visible area for each class, measured on the garment as designed. That means:

• Pockets, logos, straps and contrasting yokes reduce compliant area even though the trim is physically present.
• Reflective bands must be visible, not covered by a tool belt, radio harness or a backpack strap in normal use.
• Segmented or narrow trim contributes less continuous area than a wide band, and the arithmetic has to work.
• The class of the garment, not the width of the tape, is what a compliance officer or a customer's safety manager will check.

This is why the productive conversation with a trim supplier is about layout and area, not only about brightness.

How Does Testing Work in the United States?

Two things are tested, and they are tested separately.

Retroreflective performance is measured as a coefficient of retroreflection in candelas per lux per square metre, cd/(lx·m²), at defined observation and entrance angles, and then again after the conditioning sequence the standard requires — abrasion, flexing, cold fold, and laundering or dry cleaning as applicable. The fluorescent background is assessed for colour and colourfastness.

The conformity model differs from Europe. Under Regulation (EU) 2016/425 a high-visibility garment typically goes through EU type-examination by a notified body, with the certificate naming the garment. In the US model, the standard is consensus-based: the manufacturer or supplier declares conformity, supported by testing — commonly third-party testing at an accredited laboratory — and is responsible for the accuracy of the claim and the marking.

That difference has a commercial consequence for buyers: the paperwork you receive is the claim. Ask which edition of the standard the report references, which laboratory produced it, which garment model it covers, and whether the reported values are before or after care.

ANSI/ISEA 107 and EN ISO 20471: Can One Garment Serve Both?

The two standards share a purpose and much of their test logic, but they are not identical and are not automatically mutually acceptable. Differences exist in the type structure, the area requirements and the conformity route.

If you sell into both markets, design for the stricter of the two on area, test against both, and keep the documentation separate. Do not present an EN ISO 20471 certificate as evidence of ANSI/ISEA 107 conformity, or the reverse.

Our garment-side requirements guide covers the European framework: EN ISO 20471 requirements for reflective tape.

What Should US Buyers Verify Before Ordering?

1. The edition. Confirm the report cites the current edition of ANSI/ISEA 107 and not an earlier revision.
2. The Type. Match Type O, R or P to the actual work environment, not to what is in stock.
3. The Class and the area. Ask for the garment's visible area calculation, not just the tape's brightness.
4. Post-care values. Confirm the laundering cycle count the values refer to, and that your care label matches it.
5. The laboratory and the model. A report for a similar garment is not a report for your garment.
6. Trim specification. Product reference, width, attachment method and the trim's own test data.
7. Class E logic, if trousers are part of the outfit.

How Our Trim Maps to These Requirements

We supply the retroreflective component; the garment assessment belongs to the finished product.

• Continuous bands for Class 2 and 3 configurations — micro prismatic PVC tape in 1–15 cm widths and four thicknesses, sew-on, over 300 cd/(lx·m²).
• Wide panels where area is tight — glass-bead taffeta up to 140 cm wide, over 330 cd/(lx·m²).
• High-output programmes — industrial-wash heat transfer tape at over 420 cd/(lx·m²) after more than 50 ISO 15797 cycles, for garments with demanding laundering.
• Trim for curves and stretch panels — segmented piping and stretch piping where a rigid band cannot follow the seam.
• Flame-resistant end uses — FR heat transfer tape and two-tone FR tape where the garment standard also requires flame performance.

Frequently Asked Questions

Is a Class 3 vest always the right choice?

No. Class is matched to risk and to the work environment. A Class 3 garment in a low-risk indoor setting can be unnecessary and uncomfortable, and comfort drives whether it is actually worn.

Can I upgrade a Class 2 vest to Class 3 by adding tape?

Only if the resulting garment meets the Class 3 area and configuration requirements and is assessed as such. Adding trim without reassessment does not change the declared class.

Does an ANSI-compliant garment also satisfy EN ISO 20471?

Not automatically. Test and document separately for each market.

Do I need a notified body for the US market?

The US conformity model relies on manufacturer declaration supported by testing, not on EU-style type-examination. That places more weight on the quality of the test report you hold.

Request Trim for a US Programme

Send the garment design, the Type and Class you are targeting, the fabric, the trim width, the attachment method, the laundering regime and the order quantity. We will propose trims that fit the layout, supply angle-specific and post-care data for the exact products, and prepare samples for your own testing and for your laboratory submission.

Start from the hi-vis workwear range, the PPE material range, or the reflective materials overview.
