Functional clothing and protective equipment: standards you encounter
When clothing should not just look good but also protect.
Not all clothing should just fit well and look nice. Part of the clothing industry works with functional clothing and personal protective equipment — clothes that have a specific safety function and are therefore subject to technical standards in a quite different way than ordinary fashion clothes.
§EN ISO 20471 — visibility clothing
The standard EN ISO 20471 sets requirements for high-visibility clothing: clothing in bright, fluorescent colours like yellow, orange, and red, combined with retroreflective material that reflects light back towards the source in darkness. The idea is that the user should be visible all the way around (360 degrees) and under all lighting conditions, not just from the front.
| Class | Protection level |
|---|---|
| Class 1 | Lowest level — minimum area of fluorescent and reflective material |
| Class 2 | Mid-level — used where the risk of being overlooked is greater |
| Class 3 | Highest level — largest visible material area typically whole body covered |
§EN 469 — firefighter clothing
For a completely different purpose, EN 469 exists, which sets performance requirements for protective clothing for firefighters. The standard sets, among other things, requirements for protection against flames and radiant heat, water resistance and breathability, and a firefighter's suit that has been tested according to the standard is marked with a pictogram that shows its performance on these points.
§Why the two standards can meet
A firefighter suit can be designed so it simultaneously meets visibility requirements under EN ISO 20471 — for example by combining reflective and fluorescent materials that meet the area coverage requirements in both standards. This shows that functional clothing often must meet multiple standards at the same time, not just one isolated rule.
§What does it require of the craftsperson?
- 01Knowledge of what standard a given product must meet before material selection and design begins
- 02Understanding that seams stitching and accessories can also affect whether a product passes a test
- 03Care with documentation — functional clothing may require testing and approval, not just good workmanship
- 04Interest in a field where safety and technical precision weigh as heavily as design
“In functional clothing, a seam is not just a detail — it is part of what should save a life.”
