EN ISO 20471

High Visibility Clothing Standard

EN ISO 20471:2013+A1:2016 specifies requirements for high-visibility clothing intended to make the wearer conspicuous to vehicle and mechanized-equipment operators in daylight and under headlights in darkness. The current edition remains valid while a revision is under development.

Purpose — High-visibility protective clothing in a real worksite environment
01

Purpose

EN ISO 20471:2013+A1:2016 specifies requirements for high-visibility clothing intended to make the wearer conspicuous to vehicle and mechanized-equipment operators in daylight and under headlights in darkness. The current edition remains valid while a revision is under development.

Typical use — High-visibility protective clothing in a real worksite environment
02

Typical use

Traffic, road work, logistics, vehicle-movement areas and tasks where wearer conspicuity is critical.

What to look for? — High-visibility protective clothing in a real worksite environment
03

What to look for?

Verify EN ISO 20471 marking and garment class; visibility class relates to the areas of fluorescent and retroreflective material.

CLASSES & SELECTION LOGIC

Technical classes in this standard

A class code is not a selection decision by itself. Interpret it together with task-specific risk assessment and manufacturer data.

Lowest visibility area — High-visibility protective clothing in a real worksite environment
CLASS 1

Lowest visibility area

Lowest minimum area class for fluorescent/retroreflective material.

Intermediate level — High-visibility protective clothing in a real worksite environment
CLASS 2

Intermediate level

Class requiring a larger area of visibility materials.

Highest level — High-visibility protective clothing in a real worksite environment
CLASS 3

Highest level

Class requiring the highest minimum area of visibility materials.

READ THE PRODUCT IN THE FIELD

Where is the standard marking found?

Location varies by manufacturer and design. These are the first places to check; final verification must use the actual product and manufacturer documentation.

1
Standard and class marking on garment inner label

The marking should be legible, durable and match the product.

2
Manufacturer care/wash instructions

The marking should be legible, durable and match the product.

STANDARD FAMILY

Standards often reviewed together

EN ISO 20471:2013+A1:2016

High-visibility warning clothing

EN 17353

Enhanced visibility equipment for medium-risk situations is a different standard

COMMONLY CONFUSED

They are not the same thing

Reflective strip ≠ automatic EN ISO 20471 compliance

Garment class depends on minimum fluorescent and retroreflective material areas.

WRONG-SELECTION EXAMPLE

A typical field mistake

Treating every reflective vest as EN ISO 20471 Class 3 for high-risk traffic areas.
Why is this a problem?

Class must be verified from product marking and garment design areas.

Better approach

Determine risk level and verify the EN ISO 20471 class on the product label.

HSE FIELD CHECK

30-second field check

Use for quick pre-checks. It does not replace certification, competent inspection or task-specific risk assessment.

CHECK FOCUS

Does garment class match site risk?

CRITICAL MISTAKE

Treating every reflective vest as EN ISO 20471 Class 3 for high-risk traffic areas.

BETTER APPROACH

Determine risk level and verify the EN ISO 20471 class on the product label.

1

Does garment class match site risk?

2

Are retroreflective bands cut, detached or heavily soiled?

3

Has fluorescent fabric faded or lost conspicuity?

4

Are wash/care limits within manufacturer instructions?
