ECE 104

ECE 104 is the regulation outlining the technical requirements to approved retroreflective marking tapes for trucks and trailers in Europe.

The materials are divided in 3 classes:

Class "C": Material for contour marking
Class "D": Material for distinctive markings/graphics intended for a limited area
Class "E": Material for distinctive markings/graphics for an extended area 

In terms of reflectivity, Class "C" is the highest grade and Class "E" the lowest.

ECE 104 does not include any details about the actual application of the tapes on the vehicles - this information is found in Regulation 48.

ORAFOL, with the Reflexite brand, is the original inventer of the technology used for ECE 104 approved safety marking tapes, and today  is one of the world's leading producers in this market.

Note: When ECE 104 was included into Regulation 48, Annex 9 which previously contained application guidelines, was deleted from the regulation.

Regulation 48

Regulation 48 includes the mandate for Regulation ECE 104 markings, and specifies the conditions for this, i.e. which vehicle types must comply, which colours should be used, etc. In other words, all of the technical aspects relating to the application of the tapes, which must be approved according to the technical requirements in ECE 104.

Regulation 48 only includes the Class "C" conspicuity markings.

Because Regulation 48 deals with lighting and light-signalling devices, the classes "D" and "E" of ECE 104 are not included into, or dealt with, in this regulation. The use of these materials is left to the National authorities. Previously, when ECE 104 included application guidelines, it was a requirement that graphics made with Class D or E materials had to be placed within a full contour marking. Today, this is not a requirement in Regulation 48, but something which is decided at a national level. This means that it is something you will need to check in your own National Lighting Regulation.
