High Visibility clothing

This standard specifies PPE Clothing used where the wearer needs to be visible at day and night and where there is a risk from moving vehicles or processes. 

This standard has three different levels covering three different risks and the maximum level is class 3. The figure by the symbol indicates the area of fluorescent and reflective material within the garment. To certify and CE mark the garment with this symbol, it has to achieve one of these levels. The design of the garment is also a parameter in the CE marking of High Visibility garments. The American Standard for High-Visibility clothing is called ANSI/ISEA 107. EN ISO 20471 is an international standard also approved by the US.

Combined certification - Class 3 system

If a garment doesn´t reach EN ISO 20471 class 3, it can be combined with other Tranemo High Visibility garments to reach the highest class of certification - a Class 3 system. For example a jacket that only reaches class 2 can be worn together with a class 1 or class 2 trousers / bib & brace to reach a Class 3 system. A number of Tranemo jackets and T-shirts are approved to different EN ISO 20471 classes for various sizes and they can also be combined to a Class 3 system for all sizes. If a garment is certified as a Class 3 system it is indicated in the product description of the garment. It is also indicated on the inside CE-label of the garment.

The table below shows the Tranemo combined certification for what class the system is approved for.

Tops must be worn over a bib & brace to meet the standard requirements for combined certifications.

Tops combined with shorts or 3/4 length trousers will not be able to achieve higher than EN ISO 20471 class 2.
